Coffee Tasting and Evaluation

Move beyond broad impressions of 'strong' or 'bitter' by calibrating your palate to specialty coffee standards. Learn how to cup like a professional evaluator, isolate specific organic acids, and diagnose brew defects directly from the cup.

Like Duolingo, but for Coffee Tasting and Evaluation. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

A short one: 9 levels across 2 sections, about 18 minutes end to end, roughly 4 days at five minutes a day. It moves through The Evaluator's Palate and Diagnostic Tasting. It assumes you already know the basics.

Key ideas in Coffee Tasting and Evaluation

  • Sensory adaptation makes isolated cups taste generic or baseline to your palate
  • Direct contrast immediately highlights acidity shifts and fermentation notes
  • Side-by-side tasting creates an immediate reference point to benchmark body
  • A sharp slurp aerosolizes coffee into tiny droplets across the entire palate
  • Aerosolized droplets volatilize aromatic compounds up into the nasal cavity
  • Retronasal olfaction provides the majority of complex coffee flavor perception
  • Dry grounds release light, volatile top notes before adding hot water
  • Pushing aside the steeping coffee crust releases trapped, heavy vapors
  • Slurping the cooled liquor releases retronasal aromatics from the palate
  • High heat suppresses taste buds and masks phenolic or sour cup defects
  • Cooling coffee allows sweetness and complex fruit acidity to open up fully
  • Full immersion without stirring ensures identical extraction across all cups
  • A 1:18 ratio provides standard brew strength without masking bean defects
  • Coarse grinds prevent sediment over-extracting during extended steeping
  • Malic acid provides a crisp, round bite reminiscent of green apples or pears.
  • Citric acid produces a sharp, mouthwatering brightness typical of citrus fruits.
