Key ideas in How Coffee Gets Its Flavor
- Under-extracted coffee yields sharp, sour, and weak flavors because sweet compounds haven't dissolved yet
- Over-extracted coffee pulls out harsh, drying bitter flavors from being extracted too long
- A balanced brew hits the middle sweet spot between sour and bitter
- Finer coffee grounds create more surface area and slow down water flow
- Water rushing through too quickly leads to under-extraction and sourness
- Grinding finer increases contact time to pull out sweetness
- A brew ratio establishes the proportional balance between coffee weight and water volume
- Eyeballing coffee scoops leads to unpredictable cup strength across different brewing devices
- Water just off the boil dissolves the desirable sweet oils and sugars from coffee grounds
- Cool water fails to dissolve sweet flavor compounds, leaving the coffee thin and weak
- Freshly boiled water will not burn roasted coffee grounds during normal brewing
- Fresh roasted coffee holds trapped carbon dioxide gas inside the grounds
- Trapped gas actively pushes brewing water away, causing dry spots and uneven extraction
- The bloom step lets gas bubble out so water can saturate grounds evenly
- Desirable coffee acidity tastes like crisp, sweet, vibrant fresh fruit
- Sourness from under-extracted grounds causes a sharp, puckering grimace without sweetness
