The Flavor of Coffee
Like Duolingo, but for The Flavor of Coffee. 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 First Sip and Developing Your Palate. It starts from scratch.

Key ideas in The Flavor of Coffee
- High heat numbs the tongue's ability to perceive complex flavors
- Slurping creates a fine mist that spreads coffee over the entire palate
- Coffee's sweetness and acidity become more apparent as the liquid cools toward room temperature
- Aeration during a slurp carries aromas to the back of the nose where flavor is actually processed
- Piping hot coffee primarily registers as 'heat' and 'bitterness' rather than specific flavor notes
- A forceful slurp ensures the coffee hits all taste receptors simultaneously
- How temperature changes the sensory experience of coffee
- The functional purpose of slurping coffee
- Dry grounds reveal the most volatile, immediate aromatics
- Residual oils from one coffee can distort the flavor of the next one
- Adding water releases different 'wet' aromas like steam and oils
- Plain water resets the palate's sensitivity to acidity and sweetness
- The sequence of sensory preparation in coffee tasting
- Sweetness is most easily identified at the very front of the mouth
- Acidity in coffee is often felt as a 'sparkle' or 'tingle' on the edges of the tongue
- How to maintain taste accuracy when trying multiple coffees
