What you'll learn

Key ideas in Crafting Classic Espresso Drinks

  • Liquid espresso yield should weigh roughly double the dry ground dose
  • A standard double shot targets a 1:2 brew ratio
  • An 18g dose yields approximately 36g of liquid espresso
  • Water naturally channels through loose or thin areas of the puck
  • A flat, evenly distributed coffee bed prevents water from finding easy escape paths
  • Tamping only needs enough firm, level pressure to remove air gaps, not excessive force
  • Water first emerges as a slow, dark, syrupy drip
  • The flow then develops rich, contrasting tiger striping streams
  • The stream ends by turning pale and watery, known as blonding
  • A shot running far too fast indicates water met too little resistance from the puck
  • Finely ground coffee packs tighter and slows the water flow down into the 25-30 second window
  • Fast, under-extracted shots taste sharp, watery, and sour
  • Leaving a spent puck in place bakes dry coffee onto the hot basket and shower screen
  • A quick group flush rinses away residual bitter oils before they taint the next shot
  • A dry, wiped basket ensures new grounds settle evenly without sticking to moisture
  • A barista introduces air early while the milk is still cool
