The Home Barista
Like Duolingo, but for The Home Barista. 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 Pulling Balanced Espresso and Milk Steaming and Drink Building. It starts from scratch.

Key ideas in The Home Barista
- A standard starting espresso recipe uses a 1:2 ratio of dry grounds to liquid coffee
- Target brew time for a balanced 1:2 shot is roughly 25 to 30 seconds
- Multiplying an 18g dose by two gives a target liquid yield of 36g
- Crema contains trapped air and foam that varies wildly in volume depending on bean freshness
- A digital scale measures actual liquid mass, giving repeatable flavor shot after shot
- Visual liquid lines on a glass lead to inconsistent, unpredictable strength
- Water under high pressure searches for the path of least resistance through loose pockets
- Spreading dry grounds evenly across the whole basket before tamping prevents fast-flowing channels
- A mound left on one side creates low-density spots where water quickly bores through
- A tamp only needs enough firm, steady pressure to compress out trapped air spaces
- A crooked or unlevel tamp tilts water flow toward the shallow edge
- Pressing with extreme force does not make the coffee pack any tighter or slow down flow
- Freshly roasted coffee traps excess carbon dioxide that causes chaotic bubbling during brewing
- Resting beans for one to three weeks lets excess gas escape naturally
- Properly degassed beans produce smooth, dense, stable crema instead of fizzy foam
- Water dissolves sharp, sour fruit acids almost immediately upon contact
