How Well Do You Really Know Coffee? Advanced Edition
Beyond the basics — extraction rates, processing methods, and the third wave. For serious coffee nerds.
Beyond the basics — extraction rates, processing methods, and the third wave. For serious coffee nerds.
The Specialty Coffee Association scores beans on a 100-point scale, and only lots that hit 80 or above earn the designation "specialty coffee." This advanced quiz digs into the science, economics, and craft behind that score -- from extraction chemistry and processing innovations to origin flavor profiles and espresso mechanics. If you can explain why water at 205 °F extracts differently than water at 185 °F, you're ready.
You'll answer 10 multiple-choice questions randomly drawn from a pool of 50. Each answer is followed by an instant explanation so you learn as you go. No signup, no timer -- just expert-level coffee knowledge on demand.
Questions span roasting science (Maillard reaction, first and second crack), brewing variables (grind size, brew ratio, TDS), processing methods (washed, natural, honey, anaerobic fermentation), water chemistry, espresso engineering at 9 bars of pressure, origin profiles from Ethiopia to Sumatra, decaf processing, coffee economics, and the health research linking moderate consumption to reduced all-cause mortality.
Third wave coffee is a movement that treats coffee as an artisanal food rather than a commodity. It emphasizes single-origin sourcing, lighter roasts that highlight terroir, precise brewing parameters, and direct trade relationships with farmers. The first wave was mass-market consumption (e.g., Folgers), the second wave was espresso-bar culture (e.g., Starbucks), and the third wave focuses on quality, transparency, and craft.
The Specialty Coffee Association recommends brewing water between 195 °F and 205 °F (90.5-96 °C). Water below this range under-extracts, producing sour, thin coffee. Water above this range over-extracts, pulling out bitter compounds. Within the ideal range, hotter water extracts more quickly, so brew time and temperature should be balanced together.
In washed (wet) processing, the coffee cherry's fruit is removed before drying, producing a cleaner, brighter cup that highlights the bean's intrinsic flavors. In natural (dry) processing, the whole cherry is dried with the fruit still attached, allowing sugars to ferment into the bean and producing a fruitier, more full-bodied cup. Honey processing is a hybrid: some mucilage is left on during drying, landing between the two in flavor profile.
