Key ideas in The Perfect Cup at Home

  • Eyeballing leads to different amounts of coffee each time
  • The 1:16 ratio means 16 parts of water for every 1 part of coffee
  • Small changes in coffee weight significantly alter the final taste
  • 1:16 is the standard starting point for most brewing methods
  • Consistency requires a repeatable measurement tool
  • Multiplying coffee weight by 16 gives the target water weight
  • The necessity of measurement for consistency
  • Applying the 1:16 golden ratio
  • Coffee is almost entirely water (98%)
  • The amount of coffee determines how 'strong' or concentrated the drink feels
  • Off-flavors in tap water like chlorine transfer directly to the brewed cup
  • The grind size determines how much flavor is pulled out of the bean
  • The impact of water quality on coffee flavor
  • Cold ceramic or glass sucks heat out of the coffee instantly
  • Temperature shock destroys the subtle, pleasant smells of fresh coffee
  • Distinguishing between strength and flavor extraction
