Craft Espresso and Cafe Drinks
Learn the mechanics of dialing in balanced espresso shots, steaming silky microfoam, and constructing specialty coffee shop drinks. Build the palate and technical precision of a craft barista.
Like Duolingo, but for Craft Espresso and Cafe Drinks. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
20 levels across 4 sections, about 40 minutes end to end, roughly 8 days at five minutes a day. It moves through Nailing the Espresso Shot; Milk Texturing and Pouring; The Specialty Cafe Menu; and Dialing In Origin, Roast, and Water. It assumes you already know the basics.

Key ideas in Craft Espresso and Cafe Drinks
- Keeping dry dose fixed stabilizes puck depth while adjusting liquid yield changes total extraction
- Increasing liquid yield to 40-42g extracts more sweet and bitter compounds to balance acidity
- Changing dry dose alters puck resistance and head space, confusing your extraction readout
- Shot time is a diagnostic outcome dictated by grind size resistance, not a target to force
- Stopping a shot strictly by time sacrifices correct brew ratio and yields unpredictable strength
- If a shot reaches target yield too fast or slow, correct it by changing grind size
- Under-extraction tastes sour and thin because fast-dissolving acids dominate without sweet balance
- Over-extraction leaves a hollow, astringent dryness on the tongue from late-extracting tannins
- Fine adjustments to grind or yield steer espresso away from under- or over-extracted extremes
- Bright acids and concentrated solubles dissolve immediately in the opening seconds
- Rich sugars, caramel tones, and aromatic oils extract predominantly during the middle phase
- Astringent tannins and bitter, woody plant fibers wash out in the watery final stream
- Water carves fast paths through cracks, over-extracting bitter notes from those channels
- Denser bypassed areas remain under-extracted, contributing sour and salty acids to the cup
- Channeling produces a contradictory cup with both under- and over-extracted flavors
- WDT uses fine needles (~0.3mm) stirred from the basket base to homogenize density

Eight weeks. You meant to finish. You didn't.
Tomo gives Craft Espresso and Cafe Drinks 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 18g dose yields 36g in 28 seconds, but it tastes unpleasantly sharp and sour. How can you balance it?
