Terminology
Single origin, cupping, extraction, and specialty coffee vocabulary
Specialty coffee has developed a rich technical vocabulary: from the Specialty Coffee Association's cupping protocols to the science of extraction ratios, water chemistry, and roast development. Understanding coffee at this level requires more than familiarity; it demands the kind of active recall that only comes from repeated, structured testing.
The subject spans botany (Coffea arabica vs. Coffea canephora), agronomy (the coffee belt, altitude, soil type), processing methods (natural, washed, honey), roasting chemistry (the Maillard reaction, development time), and brewing physics. Practicing across all these dimensions ensures you can speak and write about coffee with real precision.
Frequently asked questions
- What's the difference between arabica and robusta?
- Coffea arabica grows at higher altitudes, carries more sugars and aromatic complexity, and has less caffeine. Coffea canephora (robusta) is hardier, more disease-resistant, higher in caffeine, and usually more bitter. Most specialty coffee is arabica.
- How does processing change the cup?
- Washed processing strips the fruit before drying for a cleaner, more acidic profile. Natural processing dries the whole cherry, pushing fruitier, heavier flavours. Honey processing sits between the two. The same bean can taste markedly different depending on the route it takes.
- What is cupping?
- Cupping is the industry's standardized tasting method — grinding, adding hot water, breaking the crust, and scoring aroma, acidity, body, and flavour against a protocol such as the SCA's. It lets buyers and roasters compare lots objectively.
