Key ideas in Brewing Better Coffee
- The 1:16 ratio means 1 gram of coffee for every 16 grams of water
- A digital scale measures the actual mass of the coffee, ensuring the same amount of flavor potential every time
- A standard mug of coffee requires roughly 30 grams of grounds to hit the 1:16 target
- Darker roasts are puffier and take up more space in a scoop than denser light roasts
- Deviating significantly from 1:16 results in coffee that is either too weak or unpleasantly intense
- Volume-based measurements (scoops/spoons) lead to 'mystery' cups that taste different every morning
- Boiling water can scorch coffee grounds
- Waiting after the boil reaches the sweet spot
- Tempered water extracts natural sugars
- Fresh coffee contains trapped CO2 gas
- Gas creates a barrier against water
- The bloom clears the way for extraction
- 1:16 ratio for a standard mug
- Weight vs volume for consistency
- Smaller particles have more surface area for water to touch
- Fine grinds speed up extraction
