Key ideas in Crafting Better Coffee
- Standard starting brew ratio
- Grind size and surface area
- Adjusting ratio for strength
- Coarse grinds for immersion
- Applying the Golden Ratio
- Matching grind to method
- Acids are highly soluble and dissolve almost instantly in hot water
- Applying the Golden Ratio as a tool for adjusting body and intensity
- Bitterness and astringency come from heavier compounds that require more heat and time to pull
- Under-extraction manifests as sourness and a lack of sweetness
- The sequence of flavor extraction driven by water temperature
- Over-extraction creates a dry, hollow, and unpleasantly bitter sensation
- Matching grind size to brew method based on contact time and flow rate
- Freshly roasted beans contain CO2 that physically repels water during the initial pour
- A successful bloom is signaled by bubbling and swelling of the coffee bed
- Distinguishing between under-extraction and over-extraction sensory markers
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 Crafting Better Coffee 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.
