Key ideas in The Perfect Cup at Home
- Boiling water can scorch delicate coffee compounds
- Darker roasts are puffier and take up more space in a scoop than lighter roasts
- Waiting 30-60 seconds after the boil brings water to the ideal brewing temperature
- A 'scoop' of beans can vary in actual coffee amount by several grams
- Excessive heat extracts harsh, burnt flavors from the beans
- Weight provides a repeatable ratio of water to coffee every morning
- Applying the correct temperature range to avoid bitter coffee
- Understanding why weight is superior to volume for consistency
- Grinding increases the surface area exposed to air
- Aromas are 'volatile' and begin escaping the moment the bean is cracked
- Pre-ground coffee loses its unique character much faster than whole beans
- Water follows the path of least resistance, creating 'channels' through dry spots
- A 'bloom' or initial stir ensures every grain of coffee is working to release flavor
- Recognizing the impact of timing on coffee aroma
- Dry pockets of grounds contribute no flavor to the final cup
- Identifying the cause and solution for weak, uneven extraction
