Key ideas in Brewing Better Coffee

  • Darker roasts are less dense and take up more space than lighter roasts
  • The 1:16 ratio means 1 gram of coffee for every 16 grams of water
  • A digital scale measures the actual mass of the coffee regardless of bean size or roast level
  • 1:16 provides a balance where the coffee is neither too intense nor too watery
  • Consistency in weight ensures the same amount of flavor is available for extraction every time
  • Water is measured in grams on a scale for precision (1ml = 1g)
  • Why a scale is superior to a scoop for consistency
  • Applying the 1:16 ratio to a specific amount of coffee
  • Water acts as the solvent that dilutes or concentrates the brew
  • The amount of coffee grounds determines the total potential flavor available
  • Strength is about the ratio of coffee solids to water
  • Distinguishing between strength and flavor profile adjustments
  • Under-extraction happens when water hasn't pulled enough sugars and oils from the grounds
  • Sourness is a hallmark of under-extracted coffee
  • Weakness isn't just about too much water; it's often about insufficient contact time or surface area
  • Identifying the cause of thin, sour 'weak' coffee
