Key ideas in Cold Brew Mastery and Cold Foam Craft
- A 1:8 ratio creates a ready-to-drink brew that doesn't require dilution
- Coffee grounds occupy physical space (displacement) in the brewing vessel
- A 1:4 concentrate is designed to be cut with equal parts water or milk later
- Ice melting in a 1:8 brew provides just enough dilution for a balanced cup
- Adding grounds first reduces the total volume of water the pitcher can hold
- Choosing between concentrate and ready-to-drink ratios based on intended use
- Brewers must calculate water volume based on remaining space, not pitcher capacity
- Dry pockets of coffee inside a mesh filter lead to uneven, weak extraction
- Choosing between concentrate and ready-to-drink ratios
- Hydrophobic coffee gases can trap air bubbles that block water contact
- Agitating the grounds during the initial pour ensures every grain starts brewing
- Accounting for coffee ground displacement
- Room temperature water extracts flavor compounds faster than fridge-cold water
- Starting at room temp for 2-4 hours 'kickstarts' the chemical extraction
- Immediate refrigeration slows molecular movement, requiring much longer brew times
- Identifying the purpose of the First Pour test for even saturation

One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Cold Brew Mastery and Cold Foam 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.
Here's what playing it feels like
A real question from this course. Take your best guess.
