Key ideas in How Coffee Gets Its Flavor
- Hotter water extracts flavors more quickly and deeply
- Fine grinds slow down water flow and increase surface area
- Water that is too cool fails to pull out the sweet and bitter compounds, leaving only sourness
- Coarse grinds allow water to pass through quickly and require longer soaking times
- Boiling water can over-extract and lead to a burnt, harsh taste
- Matching the 'speed' of the grind to the time the water spends touching the coffee prevents bitterness
- How water temperature affects flavor extraction
- Matching grind size to brewing method based on contact time
- Increasing the amount of coffee grounds relative to water makes the drink more concentrated
- The ratio controls the 'strength' (how much coffee is in the water) rather than the 'flavor profile'
- Water naturally follows the path of least resistance (channeling)
- Standard ratios are usually around 1 to 2 tablespoons of coffee per 6 ounces of water
- Stirring or swirling ensures every individual ground is saturated and contributing flavor
- Uneven wetting leads to a cup that is both sour and bitter at the same time
- Adjusting the coffee-to-water ratio for desired intensity
- The purpose of agitation during the brewing process
