What you'll learn

Key ideas in Espresso at Home

  • The standard espresso ratio is roughly 1:2 (grounds to liquid)
  • Water follows the path of least resistance
  • Too little liquid results in a sour, salty shot
  • An uneven or tilted coffee bed causes 'channeling' where water misses some coffee
  • Too much liquid results in a bitter, watery shot
  • A level surface is more important than raw physical strength
  • Applying the brew ratio to achieve a balanced flavor
  • Understanding the goal of tamping for water flow
  • A good shot flows in a thin, steady stream like a 'mouse tail'
  • The flow should look syrupy and viscous, not watery
  • Gushing or dripping indicates a problem with the grind or pack
  • Timing starts the moment the pump is turned on, not when the first drop hits
  • A standard shot usually takes between 25 to 30 seconds
  • Consistency in timing allows the barista to troubleshoot the grind size
  • Identifying a healthy extraction by its visual flow
  • Knowing when to start and stop the timer for consistency
