Key ideas in Better Coffee at Home
- Ratios maintain the relationship between water and coffee regardless of total volume
- Beans have different densities based on roast level
- Doubling the water requires doubling the coffee beans to keep the flavor profile identical
- Darker beans are puffier and lighter, so a scoop contains less actual coffee material
- A ratio is a recipe that scales up or down perfectly
- Weight measures the actual amount of coffee matter, while volume measures the space it takes up
- Scaling a ratio
- Density and weight
- The 1:17 ratio is a balanced starting point for most palates
- Changing the ratio primarily affects the concentration or 'strength' of the liquid
- Understanding why weight is superior to volume for coffee beans
- Personal taste dictates whether to move toward a 'tighter' ratio (like 1:15) for more intensity
- Extraction refers to how much flavor you pulled out of the grounds, usually controlled by grind or time
- Applying a ratio to maintain flavor when changing brew size
- The ratio is a guide to be adjusted, not a rigid rule
- Adding more beans makes the coffee 'stronger' without necessarily changing the quality of the flavor
