Key ideas in Making Classic Café Coffee

  • A standard brew ratio balances dry coffee weight against liquid espresso weight in the cup
  • Baristas stop the shot based on liquid output weight on a scale rather than eyeing the volume
  • Pulling the right liquid weight within roughly 25 to 30 seconds delivers a balanced extraction
  • Pressurized water automatically rushes through the thinnest or least dense part of the puck
  • Uneven coffee causes channeling, which produces shots that taste both harsh and sour at the same time
  • Leveling the dry grounds before tamping is necessary to ensure uniform resistance
  • Sour, sharp flavors extract first, meaning a rushed shot tastes aggressively tart and watery
  • Bitter, drying flavors extract last, meaning water running too long washes out harsh tastes
  • A dialed-in espresso brings sweetness and pleasant acidity into balance
  • Human tamp pressure maxes out quickly and cannot noticeably slow down 9 bars of machine pressure
  • Adjusting the grinder to a finer setting packs smaller particles closer together, slowing water flow
  • Grind size is a barista's main steering wheel for controlling extraction time
  • Freshly roasted beans are packed with trapped carbon dioxide gas that needs several days to escape
  • Excess gas erupts under brewing pressure, creating an unstable, airy foam that collapses quickly
  • Resting beans for a few days to a week allows balanced water contact and a smooth, silky crema
  • Air must be introduced early while the milk is still cold
