Tasting coffee intentionally transforms your daily cup into a sensory experience. Learn the cupping protocol used by Q Graders worldwide, how to navigate the flavour wheel, and how to develop your own palate over time.
The professional four-step protocol used by Q Graders worldwide.
Use 8.25 grams of coarsely ground coffee per 150ml of water. Grind to a coarseness similar to raw sugar. Place grounds in cupping bowls and have near-boiling water ready at 93 degrees Celsius. Smell the dry grounds first — this is the dry aroma and often reveals the most delicate fragrance notes.
Pour water directly onto the grounds and start a four-minute timer. A crust forms on the surface. At four minutes, lean in and break the crust with a spoon using three forward pushes, catching the rising steam and inhaling. This wet aroma is one of the richest sensory moments in the cupping process.
After breaking the crust, remove the foam and remaining grounds from the surface using two spoons. The coffee is then ready to taste. Wait until it cools to around 70 degrees Celsius to begin tasting — evaluating at different temperatures reveals different attributes as the cup cools.
Use a cupping spoon to draw coffee sharply into your mouth with a loud slurp. This aerates the liquid and spreads it across the entire palate simultaneously. Evaluate flavour, aftertaste, acidity, body, and balance. Professional Q Graders cup and score multiple coffees side by side to compare and rank quality.
Four things to evaluate on every coffee, in order.
The smell of brewed coffee, evaluated before tasting. Aroma compounds are largely volatile and escape quickly — evaluate immediately after brewing or breaking a crust. Descriptors range from floral and fruity to nutty, chocolatey, or smoky depending on origin and roast level.
The combined impression of taste and retronasal smell while the coffee is in your mouth. Flavour is the broadest category and encompasses every taste descriptor: citrus, berry, caramel, dark chocolate, earth, spice, tobacco. Use the flavour wheel to anchor your descriptions.
The brightness, liveliness, or tartness of the coffee. High-quality acidity is clean and refreshing, not harsh. Citric acidity (Ethiopia), malic acidity (Yemen), and phosphoric acidity (Kenya) each feel different in the mouth. Acidity generally decreases as roast level increases.
The weight and texture of the coffee in your mouth. Full body feels heavy and coating, like whole milk. Light body feels thin and watery. Body is largely determined by the amount of dissolved solids and oils in the cup. French press and immersion brews tend to produce more body than pour-over.
The World Coffee Research flavour wheel, simplified to the four main families.
One of the largest categories on the wheel, spanning berry (blueberry, strawberry, raspberry), citrus (lemon, orange, grapefruit), stone fruit (peach, cherry, nectarine), and tropical fruit (mango, papaya, guava). Fruity notes are most common in light-roasted washed and natural Ethiopians.
Includes jasmine, rose, hibiscus, lavender, and chamomile. Ethiopian Yirgacheffe coffees are the most reliably floral coffees in the world, particularly when washed and lightly roasted. Floral notes are among the most delicate and dissipate quickly — taste while the cup is still warm.
Hazelnut, almond, walnut, dark chocolate, milk chocolate, and cocoa powder fall in this section. These notes are common in Brazilian, Colombian, and Central American coffees roasted to medium levels. They are comforting, approachable, and the most recognisable flavour profile for new specialty coffee drinkers.
Includes tobacco, dark chocolate, smoke, cereal, and malt. These flavours emerge as roasting progresses and tend to dominate at medium-dark and dark levels. In moderation, roasted notes add depth. In excess, they indicate over-roasting and can mask the natural character of the origin.
Four origins, four distinctive signatures.
The birthplace of coffee. Washed Ethiopians from Yirgacheffe, Gedeo, and Guji produce jasmine, bergamot, lemon, and peach. Natural Ethiopians from Sidama and Harrar produce intense blueberry, dark cherry, and wine-like fermented notes. Ethiopia is the benchmark for complex, fruity specialty coffee.
Consistent, approachable, and versatile. Colombian coffees from Huila, Nario, and Cauca produce caramel, red apple, orange, and hazelnut. They have balanced acidity and medium body, making them ideal for espresso and filter alike. Colombian coffees are often the first step into specialty coffee.
Bold, complex, and polarising. Kenyan AA and AB grades from Nyeri, Kirinyaga, and Embu are famous for tomato-like phosphoric acidity, blackcurrant, grapefruit, and dark berry. They have full body and a long finish. At their best, Kenyan coffees are among the most complex and exciting in the world.
Heavy body, low acidity, and earthy or herbal character distinguish Sumatran coffees. Cedar, dark chocolate, tobacco, mushroom, and tropical fruit are common descriptors. The unique wet-hulling processing method called Giling Basah contributes to the characteristic earthy, syrupy profile that makes Sumatra an acquired taste.
