Coffee Tasting and Evaluation
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.
For the part of you with thirty open tabs that never became anything.
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.

Eight weeks. You meant to finish. You didn't.
Tomo gives Coffee Tasting and Evaluation the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
