Key ideas in Espresso at Home

  • Espresso requires high pressure to force water through the grounds
  • Moisture in the basket causes new grounds to clump and stick
  • The pressure creates a unique concentration and texture (crema) not found in standard brewing
  • Old grounds will over-extract and add bitter flavors to the new shot
  • Strength alone does not make a coffee an espresso
  • Water follows the path of least resistance, so any obstruction causes uneven flow
  • Distinguishing espresso from other brewing methods by its defining characteristic
  • The necessity of a clean, dry portafilter for even extraction
  • Dose, yield, and time are the primary variables used to track a recipe
  • Measuring by weight is more accurate than measuring by volume
  • An uneven coffee bed creates weak spots called channels
  • Identifying the three variables that define an espresso recipe
  • Understanding the purpose of leveling the coffee bed
  • A 'rat tail' is a thin, steady, syrupy stream that doesn't flicker
  • The flow should look viscous and slightly dark, like warm honey
  • Rapid dripping or watery flow indicates a problem with the grind or pressure
