The Home Barista's Toolkit
Like Duolingo, but for The Home Barista's Toolkit. 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 Sourcing and Preparation and The Craft of Extraction. It assumes you already know the basics.

Key ideas in The Home Barista's Toolkit
- Blends are designed for a balanced, repeatable profile that cuts through milk
- Darker roasts are more porous and release solids very quickly into water
- Single-origin beans showcase delicate, distinct regional flavors easily masked by dairy
- Lighter roasts are dense and require high heat to 'unlock' their complex acids
- Choosing between a blend and a single-origin based on the intended drink style
- Adjusting brewing variables based on the roast level's solubility
- Freshly roasted beans need several days to degas CO2 for clear flavor
- The peak window for most specialty coffee is roughly 1 to 3 weeks post-roast
- Oxidation begins to mute vibrant aromatics significantly after one month
- Natural process dries the fruit on the bean, adding body and fermented sweetness
- Washed process removes the fruit early, resulting in a clean, high-acidity cup
- High altitude slows cherry ripening, creating a harder, denser cellular structure
- Identifying the peak flavor window for roasted coffee beans
- Dense beans require more thermal energy to extract their internal sugars effectively
- Predicting the sensory profile of Washed vs. Natural processing
- Using altitude as a proxy for bean density and heat resistance
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 The Home Barista's Toolkit 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
