Dialing In Better Coffee
Like Duolingo, but for Dialing In Better 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: 12 levels across 2 sections, about 24 minutes end to end, roughly 5 days at five minutes a day. It moves through Diagnosing and Balancing Extraction and Refining the Physical Variables. It assumes you already know the basics.

Key ideas in Dialing In Better Coffee
- Bright acids wash out first while sweetness requires longer contact time
- Grassy and vegetal notes signal brewing stopped before sugars dissolved
- Grinding finer slows water flow and coaxes out sweet balancing compounds
- Heavy polyphenols wash out late in brewing to create harsh bitterness
- Over-extracted coffee loses mid-palate sweetness and tastes hollow
- Wood-like, astringent compounds dissolve after desirable sugars are spent
- Organic acidity causes salivation and perceived juiciness on the tongue
- Astringency creates a sandpaper-like dryness caused by tannin-like polyphenols
- Tactile dryness confirms over-extraction even when coffee tastes confusingly sharp
- Dissolved sugars in balanced coffee soften and round out sharp fruit acids
- Under-extraction lacks the sugar concentration needed to buffer raw acids
- Pushed too far, bitter cellular plant material overpowers delicate sweetness
- Initial extraction yields intense, concentrated sourness and saltiness
- Mid-extraction brings out syrup-like sweetness and complex aromatics
- Final flow delivers watery, astringent, and bitter wood notes
- Grinding finer creates greater surface area so water dissolves solids faster

Eight weeks. You meant to finish. You didn't.
Tomo gives Dialing In Better Coffee 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.
Here's what playing it feels like
A real question from this course. Take your best guess.
Your pour-over tastes sharply sour and grassy. What does that vegetal flavor tell you?
