Not all coffee beans are the same. Species, variety, processing method, and freshness all shape what ends up in your cup.
The dominant specialty coffee species. Arabica plants grow at higher altitudes and are more sensitive to disease and climate. The complex sugars and lower caffeine content produce nuanced, sweet, acidic flavours that specialty coffee celebrates.
Hardier and easier to grow than Arabica — resistant to disease and grows at lower altitudes with higher yields. Higher caffeine acts as a natural pesticide. Used in espresso blends for crema and body, and dominates instant coffee production.
A rare species almost entirely consumed in the Philippines and Malaysia. The beans are larger and irregular in shape. The flavour profile is polarising — woody, smoky, and floral, with a harsh finish. An acquired taste.
The coffee cherry's fruit is completely removed before the bean is dried. This strips away anything that could interfere with the bean's natural character. The result is a clean, bright cup that expresses terroir and origin flavours most clearly.
The whole cherry is dried intact — the bean ferments inside the fruit for weeks. This imparts intense fruity, wine-like, and sometimes fermented flavours. Very process-dependent. When done well, naturals are extraordinary. When done badly, they taste sour and funky.
The outer skin is removed but varying amounts of the sticky mucilage (the "honey") are left on the bean during drying. Yellow honey removes the least; black honey leaves the most. Sits between washed and natural — syrupy sweetness with more clarity than naturals.
Beans are fermented in sealed, oxygen-free tanks before or after pulping. The controlled fermentation creates unusual, intensely sweet flavour compounds that don't occur in other processing methods. Experimental and polarising — very popular in competition coffee.
One of the oldest and most widespread Arabica varieties. Produces complex, sweet cups with berry and caramel notes. Lower yield than modern varieties but exceptional quality. Foundation of many great Colombian and Rwandan coffees.
One of the earliest cultivated Arabica varieties. The genetic ancestor of many modern varieties. Produces delicate, complex cups but with very low yield — challenging to farm profitably. Found in Jamaica's Blue Mountain and Kona, Hawaii.
The world's most celebrated — and expensive — coffee variety. Originally from Ethiopia, made famous by Panama's Hacienda La Esmeralda. The tea-like delicacy, bergamot aroma, and jasmine notes are unlike anything else in the coffee world.
Developed by Scott Laboratories in Kenya specifically for the country's growing conditions. Produces the blackcurrant, tomato, and wine notes that define the iconic Kenyan cup. Difficult to grow outside Kenya — deeply terroir-dependent.
Just roasted. Lots of CO2. Wait before brewing — too fresh gives flat, under-developed flavour. Espresso especially needs degassing time.
The sweet spot. CO2 has degassed sufficiently. All the volatile aromatics are intact. This is when the roaster intended you to drink it.
Quality is declining but still very drinkable if stored properly in an airtight container away from heat and light.
Flat, dull, oxidised. Still drinkable but a pale shadow of what it was. Never buy coffee with no roast date — it's almost certainly old.
The most important label. Look for a date within the last 6 weeks. "Best before" dates are meaningless — you want to know when it was roasted, not when it expires.
Country, region, farm, or co-op. More specific is better — "Ethiopia" tells you little. "Ethiopia, Yirgacheffe, Kochere Cooperative" tells you exactly what to expect.
Washed, natural, honey, or anaerobic. This shapes the flavour profile dramatically. If you like clean and bright, go washed. If you want fruity intensity, go natural.
Bourbon, Typica, Gesha, SL28, etc. Like grape varieties in wine — the genetic makeup of the plant shapes the flavour ceiling before processing or roasting even begins.
The Specialty Coffee Association scores coffees out of 100. Specialty coffee is 80+. The very best lots score 90+. Scores above 85 represent genuinely exceptional coffee.
Higher altitude means slower cherry development and more complex sugars. Coffees above 1,800m almost always have more nuance than those grown at 800m. Not a rule, but a reliable indicator.
