How to taste coffee like a pro?

Taste in five steps: smell the fresh grind, smell the brewed cup, slurp a sip to aerate it across your palate, identify acidity, body and sweetness, then focus on the retronasal finish. Use a filter brew at 93 °C and lean on the SCA flavor wheel to put words on what you perceive.

Tasting coffee like a professional does not require lab-grade equipment — it requires a method, freshness and a trained nose. The first principle is physiological: about 80 % of what we call coffee 'taste' is actually olfaction, first through the orthonasal route (smelling the cup) and then through the retronasal route (aromas rising up the back of the throat while drinking). The tongue itself only registers five basic sensations — sweet, sour, bitter, salty, umami — plus tactile sensations like astringency or body. A trained taster consciously engages both circuits.

The method starts before the cup. Grind less than a minute before brewing: around 60 % of the volatile aromatic compounds evaporate within fifteen minutes of grinding. Use a filter method rather than espresso to learn — V60, Kalita, Chemex or french press — because filter reveals aromatic nuance where espresso concentrates and homogenises it. Water should be between 92 and 96 °C, lightly mineralised (ideally 70 to 150 ppm TDS), with a classic ratio of 60 grams of coffee per litre of water.

The tasting itself unfolds in five moves. First, the dry nose: hold the freshly ground coffee under your nose and log the fragrance — this is where the highest notes (citrus, florals) usually register most clearly. Next, the wet nose, once the coffee is brewed, nose five centimetres above the steaming cup: this captures the warm notes (caramel, ripe fruit, chocolate). The first sip waits until the coffee drops below 70 °C — any hotter and heat numbs the papillae and hides defects. Slurp loudly: oxygen atomises the liquid, droplets coat the full mouth, and vapour rises behind the palate to activate the retronasal pathway.

Focus then on three simple axes: acidity (bright and lemony, rounded like red apple, or quiet?), body (tea-light, medium like juice, or syrupy?), and sweetness (honey, brown sugar, ripe fruit?). Track the aftertaste that lingers ten to thirty seconds after swallowing. To name what you perceive without inventing, lean on the SCA flavor wheel, which organises more than a hundred descriptors from the general (fruity) to the specific (blueberry, green apple, mandarin). In Brussels, Antwerp or Walloon Brabant, specialty roasters regularly run guided tasting workshops — a valuable shortcut for calibrating your palate in under two hours.
