Espresso Extraction and Milk Craft
Like Duolingo, but for Espresso Extraction and Milk Craft. 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 Dialing the Shot and Milk Physics and Bean Variables. It assumes you already know the basics.

Key ideas in Espresso Extraction and Milk Craft
- Blonding occurs when desirable soluble sugars are fully depleted from the coffee puck.
- Continuing past blonding washes out harsh, astringent compounds into the cup.
- Cutting the shot at the onset of blonding protects sweetness and tactile body.
- A bottomless portafilter sprays fine spurts or shows rapid localized pale streams.
- Channeling creates both sharp sour notes and dry bitterness in the exact same cup.
- Rushed brew times accompanied by hollow, watery body point to bypassed grounds.
- Under-extracted shots hit the tongue sides with sharp, sour malic and citric acids.
- Over-extracted coffee coats the back of the palate with dry, powdery bitterness.
- Uneven flow causes simultaneous sourness and bitter astringency in a single sip.
- Grinding finer increases bed resistance, worsening channeling through clumped areas.
- Even needle distribution breaks up micro-clumps before tamping to stabilize flow.
- Grinder adjustments are only meaningful once distribution creates uniform bed density.
- Yield in the cup dictates your brew ratio and should never be altered just to fill time.
- Shot time is a diagnostic readout that tells you whether your grind size was correct.
- Stop the shot immediately at target yield, taste it, and grind finer for the next run.
- A shorter yield increases TDS concentration but pulls fewer total compounds from grounds.
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Espresso Extraction and Milk Craft 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.
