Key ideas in How Coffee Gets Its Flavor

  • Coffee flavor peaks shortly after roasting and fades over weeks
  • Using more coffee grounds relative to water increases the concentration of flavors
  • Roasted beans are a perishable product that loses aroma when exposed to air
  • The ratio of coffee to water is the primary lever for body and intensity
  • A 'roasted on' date is a better indicator of quality than an 'expiration' date
  • Adding more water dilutes the final brew
  • The impact of roasting dates on coffee flavor quality
  • Adjusting the coffee-to-water ratio to change drink strength
  • Extremely hot water extracts bitter compounds too quickly
  • Small particles brew faster than large ones
  • Water that is too cool fails to pull out the sugars and oils
  • Uneven grounds lead to some parts being over-extracted (bitter) and others under-extracted (sour) in the same cup
  • The 'sweet spot' for extraction is just below the boiling point
  • A uniform grind size allows all grounds to finish brewing at the same time
  • How water temperature affects flavor extraction
  • The importance of grind consistency for even flavor
