Espresso Drinks: Craft and Technique
Move beyond guesswork to dial in balanced espresso shots and texture cafe-grade microfoam. Master extraction diagnostics, milk chemistry, and drink ratios to build classic cafe beverages with consistency.
Like Duolingo, but for Espresso Drinks: Craft and Technique. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
24 levels across 4 sections, about 48 minutes end to end, roughly 10 days at five minutes a day. It moves through Nailing the Core Extraction, Mastering Milk Dynamics, Drink Architecture and Formulations, and Machine and Material Variables. It assumes you already know the basics.

Key ideas in Espresso Drinks: Craft and Technique
- Locking dry dose and liquid yield keeps beverage concentration stable across attempts.
- Changing grind size alone reveals whether flow resistance is the real issue.
- Altering dose and grind together obscures which change corrected the extraction.
- A 1:2 ratio serves as the standard sensory baseline for modern espresso profiles.
- Short restricted ratios capture dense oils and vivid acidity before bitter notes emerge.
- Longer extended ratios pull extra sweetness and clarity while thinning mouthfeel.
- Yield weight governs extraction yield and cup strength more reliably than run time.
- Contact time is a diagnostic readout indicating how tightly the puck resisted water.
- Stopping a shot strictly on time alters your brew ratio and spoils taste consistency.
- High-velocity squirts spraying from the basket base pinpoint puck fissures.
- Multiple isolated dripping streams that refuse to merge show localized dry patches.
- Sudden local blonding within five seconds indicates early wash-through of solubles.
- Keep the dry dose weight and liquid target yield identical to the previous attempt.
- Shift the grinder collar one or two notches finer to build puck resistance.
- Purge retained grounds from the burr chamber before grinding the fresh dose.
- Pull the test shot to assess the new flow rate against the diagnostic window.

Eight weeks. You meant to finish. You didn't.
Tomo gives Espresso Drinks: Craft and Technique 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 espresso runs too fast. What single thing should you adjust to see if flow resistance is the problem?
