What you'll learn

Key ideas in Everyday Barista Skills

  • A standard espresso brew ratio is 1:2 (one part dry ground coffee to two parts liquid espresso)
  • Dosing 18 grams of dry coffee yields 36 grams of brewed espresso
  • Weighing the liquid output on a scale tells you exactly when to stop the shot
  • Pressurized water always seeks the path of least resistance through the coffee puck
  • A crooked tamp or uneven coffee distribution creates weak spots called channels
  • Channeling results in a shot that tastes simultaneously sour and harsh
  • Shot time serves as an indicator of how much resistance the puck offers to the water
  • A shot running too fast means grounds are too coarse to slow the water down
  • A shot that chokes or drips too slowly means grounds are packed too tightly and ground too fine
  • Espresso extracts heavy, dark, viscous syrups containing sour acids and concentrated oils first
  • The stream shifts into a rich, golden-brown flow carrying balanced sweetness
  • Toward the end of extraction, the stream thins and turns pale yellow (blonding), adding bitter, watery notes
  • Acidic and sour components wash out of the grounds first
  • Sugars and body dissolve during the middle of the brew
  • Bitter, harsh notes only dissolve at the very end of extraction
  • A sour, puckering taste indicates under-extraction
