Key ideas in Brewing Better Coffee at Home
- Coffee is mostly water, so the concentration of coffee solids determines strength
- Roasting changes the density of the bean
- Adding more coffee grounds relative to the water volume makes the drink more intense
- Darker beans are puffier and lighter, while light beans are smaller and heavier
- A scale measures the actual mass of coffee regardless of how much space the beans take up
- Understanding that the ratio of coffee to water is the primary control for strength
- Recognizing why weight is more reliable than volume for measuring coffee
- The 1:16 ratio is the industry standard for drip coffee
- This ratio provides enough water to extract flavor without over-diluting the cup
- Coffee to water ratio is the primary control for strength
- Less water (a tighter ratio) creates a thicker 'body' or texture
- More water (a wider ratio) thins out the texture of the coffee
- Weight is more reliable than volume for measuring coffee
- The ratio affects the physical weight of the liquid on the tongue
- Boiling water can scorch grounds
- Standard starting ratio
