Introduction

The journey from coffee cherry to morning brew spans thousands of miles and countless decisions. For home baristas, understanding coffee origins extends far beyond marking a country on a map – it provides practical insights that influence our daily brewing choices. Whether you’re pulling shots on a Sage Dual Boiler in Manchester or crafting pour-overs with a Chemex in Edinburgh, the characteristics of your chosen origin affect every step of the brewing process.

When browsing your local roaster’s offerings, you’ll notice distinct patterns. Ethiopian beans often command premium prices and feature prominently in speciality coffee shops, while Brazilian coffees form the backbone of many espresso blends. These patterns emerge from the unique growing conditions of each region, translating directly into the cup qualities we experience at home.

Consider a typical morning espresso scenario: beans from Guatemala’s Huehuetenango region might require a slightly finer grind and lower brew temperature than your usual Brazilian Santos. This isn’t coffee snobbery – it’s practical knowledge that helps extract the best from your beans. The dense, high-altitude Guatemalan beans contain different compounds and cellular structures compared to their Brazilian counterparts, demanding subtle but important adjustments to your brewing approach.

The key characteristics that define a coffee’s origin include:

• Growing altitude (metres above sea level)
• Annual rainfall patterns
• Soil mineral content
• Traditional processing methods
• Typical varietals grown

Understanding these elements helps decode the information often found on UK coffee packaging. When a roaster describes their Ethiopian Yirgacheffe as “grown at 1,900 metres in red volcanic soil,” this translates to practical brewing guidance. These conditions typically produce dense beans requiring longer extraction times and higher temperatures to fully develop their characteristic floral notes.

For the UK home barista, origin knowledge proves particularly valuable when adapting to our water composition. London’s hard water might require different brewing adjustments for a delicate Kenyan coffee compared to the soft water found in Manchester. This guide will explore these regional characteristics in detail, providing practical insights for improving your daily brewing routine.

Through understanding origins, we develop more than just knowledge – we gain practical tools for consistently better coffee. The following sections will examine each major growing region, translating their unique characteristics into actionable brewing advice for the UK home barista.

Understanding Coffee Growing Fundamentals

The environment where coffee grows shapes its fundamental characteristics long before it reaches your grinder in Brighton or Belfast. These growing conditions create distinct patterns in the bean’s cellular structure, density, and chemical composition – factors that directly influence your brewing decisions at home.

Altitude’s Influence

Altitude plays perhaps the most crucial role in coffee development. As elevation increases, temperatures drop and growth slows, allowing more time for complex flavour compounds to develop within the bean. A coffee plant growing at 1,800 metres experiences vastly different conditions from one at 800 metres, even on the same mountainside.

For home brewing, altitude typically correlates with these key characteristics:

• Higher density beans (above 1,500m)
• Increased acidity (above 1,700m)
• Greater flavour complexity (above 1,600m)
• Harder bean structure (above 1,400m)
• Higher concentration of sugars (above 1,500m)

These characteristics demand specific adjustments in your brewing approach. Higher-grown coffees typically require finer grinding, higher brewing temperatures, and often benefit from longer extraction times. For example, when brewing a high-altitude Colombian Supremo on your V60, you might find better results with water at 96°C rather than the standard 94°C recommendation.

Climate Factors

Coffee grows in what’s known as the “bean belt” – the tropical and subtropical regions between the Tropics of Cancer and Capricorn. However, significant variations exist within this belt. The alternating wet and dry seasons of Ethiopia’s Sidamo region create different growing conditions from the more consistent rainfall patterns of Colombia’s coffee triangle.

These seasonal patterns influence bean development and harvesting times. In regions with distinct wet and dry seasons, coffee cherries often ripen more uniformly, leading to more consistent beans. This translates to more predictable brewing behaviour in your kitchen – particularly important when dialling in espresso shots.

Soil Composition

Soil composition affects both the plant’s nutrition and the minerals available during bean development. Volcanic soils, common in parts of Central America and East Africa, provide distinct mineral profiles that influence flavour development. The iron-rich red soils of Brazil’s Minas Gerais region create different growing conditions from the volcanic loam of Guatemala’s Antigua Valley.

Understanding soil types helps predict a coffee’s likely characteristics:

• Volcanic soil (bright, clean acidity)
• Clay-rich soil (fuller body)
• Sandy soil (lighter body)
• Limestone-rich soil (sweet, complex)

This knowledge proves particularly relevant when adjusting extraction parameters. Coffees from volcanic soils often benefit from slightly longer brewing times to fully develop their characteristic brightness, while those from clay-rich soils might require shorter extractions to avoid over-extracted bitter notes.

Processing Methods

While not strictly a growing condition, processing methods typically follow regional patterns and significantly influence how we approach brewing. The tradition of natural processing in Ethiopia’s Sidamo region creates fundamentally different beans from the washed coffees of neighbouring Kenya.

Processing affects internal bean structure and requires specific brewing adjustments:

• Natural process: Lower temperatures, coarser grind
• Washed process: Higher temperatures, finer grind
• Honey process: Medium temperatures, medium-fine grind

For the home barista, these fundamentals provide a framework for approaching new coffees. When your local roaster offers a new natural-processed Ethiopian coffee, you can start with slightly lower brewing temperatures and adjust from there, rather than beginning from scratch with your recipe development.

Understanding these growing fundamentals helps decode the information provided by UK roasters and translates directly into practical brewing adjustments. These factors create a foundation for exploring specific growing regions and their characteristics in more detail.

Major Growing Regions

Central America

Central American coffees maintain a strong presence in UK speciality coffee shops, particularly for espresso-based drinks, owing to their consistent flavour profiles and versatile brewing characteristics. The region’s volcanic soil, high altitudes, and established processing infrastructure create distinct coffee characteristics that work well with British brewing water and common home equipment.

Guatemala stands out for its diverse growing regions, each with unique profiles. The Antigua Valley, surrounded by three volcanoes, produces coffees with remarkable complexity. When brewing Antigua coffees on a typical home espresso machine, starting parameters often align well with standard settings:

• Brewing temperature: 93-94°C
• Extraction time: 25-28 seconds
• Brew ratio: 1:2 (coffee to water)
• Grind: Medium-fine
• Rest period: 7-10 days post-roast

Costa Rican coffees, particularly those from the Tarrazu region, demonstrate remarkable consistency in the cup. The strict government controls on coffee production translate into predictable brewing behaviour – particularly valuable when learning to dial in espresso. These coffees often require slightly higher temperatures than their Guatemalan counterparts to fully develop their characteristic bright acidity.

Honduran coffees, increasingly available through UK speciality roasters, offer excellent value while maintaining high quality. The Santa Barbara region produces particularly notable coffees, though they often benefit from slightly longer rest periods post-roast compared to other Central American origins. When brewing Honduran coffees as filter, extend your usual blooming time by 10-15 seconds to aid even extraction.

El Salvador’s bourbon-variety coffees, despite lower growing altitudes than some neighbours, produce excellent results in milk-based drinks. Their characteristic caramel sweetness cuts through milk particularly well, making them popular choices for home baristas who enjoy flat whites or cappuccinos. The dense bean structure often requires a finer grind than you might expect for the altitude.

Regional processing methods significantly influence brewing approaches. While most Central American coffees undergo washed processing, variations exist. The honey process, popular in Costa Rica, creates beans requiring specific adjustments:

• Lower brewing temperatures
• Coarser grind settings
• Shorter extraction times
• Extended degassing periods
• Gentler tamping pressure

For filter brewing, Central American coffees typically excel with paper filters rather than metal, as the cleaner cup profile highlights their subtle complexity. When using a V60 or Chemex, maintain a consistent pour pattern and pay particular attention to bed levelness during drawdown – these coffees can be sensitive to channeling due to their dense bean structure.

The region’s fairly consistent harvest season, typically December through March, means UK roasters often receive fresh crop arrivals in late spring. This timing allows for optimal bean development before the coffee reaches your grinder. When purchasing Central American coffees, check the harvest dates usually provided on speciality roasters’ websites – beans from the previous year’s harvest might require brewing adjustments as they age.

Understanding water composition becomes particularly relevant with Central American coffees. Their balanced acid structure interacts notably with mineral content. For London’s hard water, consider reducing brew temperature by 1°C from your standard parameters. Conversely, in soft water areas like Manchester or Glasgow, you might need to increase temperature slightly to achieve optimal extraction.

These regional characteristics create a reliable foundation for home brewing, particularly valuable for those new to speciality coffee. Central American coffees provide consistent, predictable results while offering enough complexity to reward experimentation with brewing parameters. The next section will explore South American growing regions, where different climatic conditions create distinct challenges and opportunities for the home barista.

South America

Brazil

Brazil’s vast coffee-growing regions produce nearly a third of the world’s coffee, significantly influencing UK coffee culture through their prominence in espresso blends. The lower-altitude growing conditions and distinct processing methods create beans with particular brewing requirements that differ notably from other origins.

The Minas Gerais region, Brazil’s largest coffee producer, typically grows coffee between 800-1,200 metres. These relatively low altitudes create less dense beans with prominent chocolate and nut characteristics. When brewing Brazilian coffees as espresso, typical starting parameters often differ from other origins:

• Brewing temperature: 91-92°C
• Grind setting: Slightly coarser
• Extraction time: 23-25 seconds
• Pre-infusion time: 3-4 seconds
• Brew ratio: 1:2.2

Natural processing dominates Brazilian coffee production, particularly in the Sul de Minas region. This process creates beans requiring specific storage and brewing considerations. Brazilian naturals often benefit from longer rest periods post-roast, typically 10-14 days before optimal flavour development for espresso. The beans’ cellular structure changes more significantly during roasting, requiring careful grinder adjustment as they age.

Colombia

Colombian coffee’s reputation for consistency stems from the country’s unique agricultural infrastructure and varying harvest seasons. The main regions of Huila, Nariño, and Caldas offer distinct profiles while maintaining characteristic Colombian attributes. Growing altitudes typically range from 1,200 to 2,000 metres, creating denser beans that require specific brewing approaches.

When brewing Colombian coffee through filter methods, water chemistry plays a crucial role. The high mineral content of many UK water supplies, particularly in the south east, can overshadow Colombian coffee’s subtle acidity. Consider these water adjustments for optimal results:

• Total Hardness: 75-125 ppm
• Alkalinity: 40-50 ppm
• pH: 7.0-7.2
• Temperature: 94-96°C
• Total Dissolved Solids: 150-200 ppm

The Colombian Coffee Growers Federation’s strict quality controls create remarkably consistent beans. This consistency allows home baristas to develop reliable brewing recipes. For pour-over brewing, Colombian coffees often excel with a specific approach focused on even extraction:

Keep these pour-over parameters consistent:

• Total brew time: 2:45-3:15
• Bloom phase: 45 seconds
• Water additions: 3-4 pours
• Final bed depth: 2.5-3cm
• Drawdown time: 45-60 seconds

Peru

Peruvian coffees, increasingly available through UK speciality roasters, offer unique challenges and opportunities for home brewing. The high growing altitudes of regions like Cajamarca (1,500-2,100 metres) create extremely dense beans requiring specific grinding and brewing adjustments.

When brewing Peruvian coffees as filter, conventional wisdom about grind size often needs revision. The extreme density of these high-grown beans means that even apparently coarse grounds can restrict flow rate. Start with a slightly coarser grind than usual for any given brewing method, then adjust based on taste rather than visual assessment of the grounds.

Ecuador

Ecuadorian speciality coffee, though less common in UK shops, offers distinctive characteristics particularly suited to modern light-roast filter brewing. The volcanic soils of the Pichincha region create beans with high mineral content that interact uniquely with different water compositions.

For optimal results with Ecuadorian coffees, consider adjusting standard filter brewing parameters. The beans’ high density and mineral content often benefit from higher brewing temperatures and longer contact times than typically recommended. When using hard water, common in many UK regions, extend the bloom time to 45-60 seconds to help neutralise the impact of high mineral content on extraction.

South American coffees, particularly from Brazil and Colombia, form the backbone of many UK roasters’ offerings. Understanding their distinct characteristics and required brewing adjustments helps achieve consistent results at home. These origins often prove especially forgiving when learning to dial in espresso or perfecting pour-over technique, making them excellent choices for developing your coffee brewing skills.

Africa

Ethiopia

Ethiopian coffees occupy a unique position in UK speciality coffee culture, particularly among filter coffee enthusiasts. The birthplace of coffee offers distinct regional variations that require specific brewing approaches to fully express their characteristics. The primary growing regions of Yirgacheffe, Sidamo, and Guji each present different challenges for the home barista.

Yirgacheffe coffees, grown at altitudes between 1,800-2,200 metres, produce notably dense beans with complex floral and citrus notes. When brewing these coffees as filter, conventional parameters often need adjustment. The high density and complex acid structure typically require higher brewing temperatures and longer contact times than coffees from other origins.

For V60 brewing of Yirgacheffe coffees, consider these starting parameters:

• Water temperature: 96-98°C
• Total brew time: 3:15-3:45
• Bloom duration: 45-60 seconds
• Coffee to water ratio: 1:16.5
• Filter paper: Bleached

Natural processed Ethiopian coffees, particularly common from Sidamo, behave differently from their washed counterparts. The processing method creates more porous beans that extract more readily. When brewing natural Ethiopians, reduce your water temperature by 2-3°C from your usual parameters and consider a slightly coarser grind to prevent over-extraction.

Kenya

Kenyan coffees present unique challenges for UK home baristas, particularly regarding water chemistry. The distinctive phosphoric acid content of Kenyan beans interacts notably with mineral-rich water, common in many UK regions. This interaction often requires specific adjustments to achieve optimal extraction.

The SL28 and SL34 varieties, common in Kenyan coffee, produce beans with high acid content. When brewing these coffees in hard water areas like London or Bath, consider these water adjustments:

• Reduce mineral content (use filter)
• Lower brewing temperature: 92-94°C
• Increase brew ratio slightly: 1:17
• Extended bloom time: 45 seconds
• Gentler pouring technique

Rwanda

Rwandan coffees, increasingly available through UK speciality roasters, offer excellent brewing characteristics particularly suited to modern filter methods. The high growing altitudes (1,700-2,000 metres) create dense beans that benefit from specific grinding approaches.

The Bourbon variety, common in Rwanda, produces particularly hard beans that often require grinder adjustments. When using a typical home grinder like the Wilfa Uniform or Fellow Ode, you might need to adjust 2-3 settings finer than your usual filter setting. The dense bean structure also benefits from slightly higher brewing temperatures to ensure proper extraction.

Tanzania

Tanzanian coffees from the northern regions near Kilimanjaro demonstrate particular sensitivity to brewing water temperature. The peaberry variety, common in UK speciality shops, requires specific brewing adjustments due to its unique bean morphology.

When brewing Tanzanian peaberry coffees, standard parameters often need revision:

• Grind size: One step finer
• Water temperature: 94-95°C
• Brew ratio: 1:15.5
• Pour pattern: Gentler, more pulses
• Total brew time: 2:45-3:15

Uganda

Ugandan speciality coffee, though less common in UK shops, offers distinct characteristics that reward careful brewing attention. The natural Bugisu coffees, in particular, require specific adjustments to typical brewing parameters. These coffees often display more body than other East African origins, requiring careful attention to filtration methods.

The relatively young speciality coffee sector in Uganda produces beans that often benefit from extended rest periods post-roast. When brewing these coffees, particularly as filter, allow 10-14 days from roast date before expecting optimal results. The cellular structure continues to stabilise during this period, affecting extraction patterns and flavour development.

African coffees present some of the most distinctive and rewarding brewing experiences for UK home baristas. Their unique characteristics often require more precise brewing control than coffees from other origins, but this attention to detail typically yields excellent results. Understanding these regional variations helps develop more precise brewing techniques applicable across all origins.

Asia Pacific

Indonesia

Indonesian coffees present unique challenges for UK home baristas, largely due to their distinctive processing methods and growing conditions. The wet-hulled process, known locally as ‘Giling Basah’, creates beans with specific brewing requirements that differ significantly from other origins.

Sumatran coffees, particularly those from the Mandheling region, typically display lower acidity and heavier body than other origins. These characteristics require specific brewing adjustments for optimal extraction. When brewing Sumatran coffees as filter, conventional wisdom about brewing temperature often needs revision. The cellular structure of wet-hulled beans benefits from lower brewing temperatures than typically recommended for filter coffee.

For brewing Indonesian wet-hulled coffees, start with these adjusted parameters:

• Water temperature: 89-91°C
• Grind size: Slightly coarser
• Total brew time: 2:30-3:00
• Brew ratio: 1:15
• Filter paper: Natural (brown)

India

Indian coffees, particularly those from the Western Ghats region, offer distinct brewing characteristics that suit both filter and espresso preparation. The monsooned Malabar process, unique to India, creates beans with specific requirements for storage and brewing.

Monsooned Malabar coffees require careful storage in the UK’s humid climate. These beans absorb moisture readily, affecting grinding and extraction characteristics. When brewing monsooned coffees, particularly as espresso, grinder adjustments become more frequent and significant. The beans’ unique structure often requires:

• Daily grinder adjustments
• Lower dose weights
• Shorter extraction times
• Reduced brewing pressure
• More frequent cleaning cycles

Vietnam

Vietnamese coffees, though less common in UK speciality shops, offer unique opportunities for experimental brewing methods. The Robusta varieties, grown at lower altitudes, produce dense beans with high caffeine content and specific extraction characteristics.

When brewing Vietnamese beans, particularly for traditional style preparation, water temperature becomes crucial. The higher caffeine content and dense bean structure require careful temperature management to avoid over-extraction and excessive bitterness. Consider using a temperature-controlled kettle and starting at lower temperatures than typical for other origins.

Papua New Guinea

Papua New Guinea’s coffees, particularly those from the Eastern Highlands, present specific challenges for home brewing. The high humidity during processing creates beans that often benefit from extended rest periods post-roast. When brewing PNG coffees as filter, the beans’ moisture content affects extraction patterns significantly.

The unique processing conditions in PNG create beans requiring specific storage considerations in the UK climate. Before brewing, these coffees often benefit from:

• Extended rest period (14 days)
• Airtight container storage
• Regular grinder adjustment
• Lower humidity environment
• Careful temperature control

These growing areas represent some of the most distinctive coffee origins available to UK home baristas. The processing methods and growing conditions create beans that often challenge conventional brewing wisdom, requiring specific adjustments to achieve optimal results. Understanding these regional characteristics helps develop more nuanced brewing approaches and broadens your coffee preparation skills.

The following section examines seasonal coffee patterns, helping UK home baristas understand when different origins reach peak availability and how this affects brewing decisions throughout the year.

Seasonal Coffee Guide

Understanding Harvest Cycles

Coffee harvesting follows distinct seasonal patterns that directly affect bean availability and quality in the UK market. Understanding these cycles helps home baristas plan their bean purchases and adjust expectations throughout the year. While vacuum-sealed green beans remain stable for months, understanding harvest timing helps predict when fresh crop coffees will arrive at UK roasters.

Central American harvests typically occur between December and March, with these coffees arriving in the UK between April and June. These fresh crop arrivals often require slightly different brewing parameters compared to the same origins later in the year. Early-season Central American coffees frequently benefit from longer rest periods post-roast, typically requiring:

• Extended degassing time: 10-14 days
• Higher brewing temperature: +1°C
• Coarser initial grind setting
• Longer pre-infusion periods
• Gentler brewing pressure

Peak Buying Periods

Ethiopian and Kenyan coffees typically reach UK roasters between July and September, following their winter/spring harvests. These East African arrivals often display more vibrant acidity in their first months of availability, requiring careful brewing adjustment. The intense flavour compounds gradually mellow, meaning brewing parameters might need revision throughout the coffee’s shelf life.

For optimal results with fresh crop East African coffees, consider these storage guidelines:

• Airtight container usage
• Cool storage temperature: 16-19°C
• Away from direct sunlight
• Minimal temperature fluctuation
• Regular container rotation

Storage Considerations

The UK’s humid climate presents specific challenges for coffee storage. Beans from different origins respond differently to ambient moisture levels. Indonesian coffees, particularly wet-hulled varieties, require extra attention to storage conditions in British weather. These coffees often benefit from vacuum-sealed containers or speciality coffee storage vessels with one-way valves.

Brazilian coffees, arriving in UK shops between October and December, typically demonstrate more stable characteristics throughout their shelf life. The lower growing altitudes and processing methods create beans less susceptible to environmental changes. However, natural processed Brazilian coffees still require careful storage to maintain their distinctive fruity notes.

Seasonal Brewing Adjustments

Ambient temperature and humidity in the UK affect coffee grinding and extraction throughout the year. Summer months often require finer grind settings as beans become more brittle in warmer conditions. Conversely, winter’s higher humidity levels might necessitate coarser grinding to maintain consistent flow rates.

Consider these seasonal equipment adjustments:

• Regular grinder calibration
• Temperature monitoring
• Humidity measurement
• Water filter changes
• Equipment cleaning frequency

Year-Round Availability

Some origins maintain more consistent availability due to multiple harvest seasons or strategic green coffee storage. Colombian coffees, with their varying regional harvest times, often provide fresh crop options throughout the year. This consistency allows home baristas to develop reliable brewing recipes without constant seasonal adjustment.

Understanding these seasonal patterns helps UK home baristas make informed decisions about bean purchases and storage methods. While vacuum-sealed beans remain stable for months post-harvest, recognising peak seasons for different origins helps predict when fresh crop coffees will display their most distinctive characteristics. This knowledge, combined with appropriate storage methods, helps maintain consistent brewing results throughout the year.

Practical Applications

Choosing Beans Based on Brewing Method

Different brewing methods extract varying compounds from coffee beans, making some origins more suitable for specific preparation techniques. Understanding these relationships helps select appropriate beans for your preferred brewing method and equipment capabilities.

For espresso preparation, particularly on prosumer machines common in UK homes like the Sage Dual Boiler or Lelit MaraX, Brazilian and Colombian coffees often provide consistent results. These origins typically offer forgiving extraction characteristics and perform well across varying pressure profiles. Their moderate density and balanced acid structure create predictable extraction patterns, particularly valuable when learning to dial in shots.

When brewing filter coffee through methods like the V60 or Kalita Wave, high-grown African coffees often excel. These brewing parameters typically work well with Ethiopian coffees:

• Water temperature: 94-96°C
• Total brew time: 3:00-3:30
• Coffee to water ratio: 1:16.5
• Pour intervals: 30-45 seconds
• Final bed depth: 2.5-3cm

Adjusting Brewing Parameters

Regional characteristics often require specific parameter adjustments. For instance, dense Kenyan beans typically need finer grinding than Brazilian coffees of similar roast level. When switching origins, consider these initial adjustments:

Higher altitude origins (>1,800m):

• Finer grind setting
• Higher brew temperature
• Longer extraction time
• Extended pre-infusion
• Increased agitation

Blending Considerations

Understanding origin characteristics proves particularly valuable when creating home blends. Different origins contribute specific attributes to blends, affecting overall cup profile and extraction behaviour. For example, Brazilian naturals often provide body and chocolate notes, while washed Ethiopians contribute brightness and complexity.

Common UK Roaster Offerings

UK speciality roasters typically maintain consistent offerings from specific origins, allowing home baristas to develop familiarity with regional characteristics. House espresso blends often combine Brazilian or Colombian base notes with Ethiopian or Central American accent coffees. This knowledge helps predict brewing behaviour when trying new roasters or blends.

Consider these common parameters when approaching new roaster offerings:

For darker roasted Brazilian blends:

• Lower brew temperature: 91-92°C
• Shorter extraction time
• Coarser grind setting

Understanding these practical applications helps develop more consistent brewing results across different origins. The following section examines how to develop tasting skills specifically related to origin characteristics, enhancing your ability to identify and work with regional coffee traits.

Tasting and Development

Building a Origin-Based Tasting Framework

Developing the ability to identify and work with origin characteristics forms a crucial skill for home baristas. This process involves systematic tasting, careful note-taking, and understanding how different origins express themselves through various brewing methods. While coffee tasting often seems subjective, certain regional characteristics remain consistent and identifiable.

The UK’s diverse speciality coffee scene provides excellent opportunities to develop origin-specific tasting skills. Many roasters offer cupping sessions and tasting flights, allowing direct comparison of regional characteristics. However, systematic home tasting proves equally valuable for developing these skills.

Begin by establishing a consistent tasting environment. Common household variables that affect taste perception include:

• Room temperature: 19-21°C
• Natural lighting conditions
• Clean palate (no strong foods)
• Consistent cupping vessels
• Filtered room air

Understanding regional flavour profiles requires experience with multiple examples from each origin. Start with major growing regions like Ethiopia, Colombia, and Brazil. These origins often display consistent characteristics that help develop reliable reference points. Ethiopian Yirgacheffe coffees, for instance, typically exhibit floral and citrus notes, while Brazilian Santos coffees show nutty and chocolate characteristics.

Developing Palate Awareness

Palate development requires structured practice. Begin by focusing on basic taste categories: sweetness, acidity, body, and finish. These fundamental characteristics vary predictably by origin. Central American coffees typically display medium body and balanced acidity, while Indonesian coffees often show fuller body and lower acidity.

Record your tasting observations systematically. A basic tasting framework should include:

• Origin details
• Processing method
• Brewing parameters
• Initial impressions
• Developing flavours

Keeping Useful Notes

Effective tasting notes help track origin characteristics over time. Rather than focusing on specific flavour descriptors, record brewing parameters and cup characteristics that help replicate successful results. Note how different origins respond to brewing adjustments, particularly regarding extraction time and temperature.

This systematic approach to tasting helps develop practical origin knowledge applicable to daily brewing. The following sections examine specific growing regions and their characteristic flavour profiles in detail.
