Key ideas in Better Coffee at Home
- Coffee strength is primarily controlled by the ratio of coffee grounds to water
- An expensive machine cannot fix coffee that was brewed with too much or too little water
- Coffee beans vary in size, roast density, and settle irregularly in a spoon
- A scale measures actual mass, ensuring identical coffee dosing every single brew
- The standard balanced coffee ratio is 1 gram of coffee to 16 grams of water
- To find the water needed, multiply ground coffee weight by 16 (20g coffee × 16 = 320g water)
- Hot water just off the boil extracts desirable coffee solubles quickly and completely
- Lukewarm water fails to pull sweet, rich compounds out of the grounds, leaving a sour taste
- Brewed coffee is over 98% water, so tap water flaws directly degrade the final cup
- Chlorine in tap water imparts chemical off-flavors that mask coffee's natural sweetness
- The standard balanced coffee ratio is 1 gram of coffee to 16 grams of water; To find the water needed, multiply ground coffee weight by 16 (20g coffee × 16 = 320g water)
- Filtering removes harsh impurities so subtle fruit and floral notes in the coffee bean can shine through
- Hot water just off the boil extracts desirable coffee solubles quickly and completely; Lukewarm water fails to pull sweet, rich compounds out of the grounds, leaving a sour taste
- Finely ground coffee creates far more exposed surface area for water to touch
- Water pulls soluble coffee flavors out much more rapidly across finer particles
- Coarse chunks force water to travel deeper into the bean particle to pull flavors
