  • 0:00-0:30: Pour twice the weight of coffee in water (e.g., 44g for 22g coffee) for the bloom phase.
  • 0:30-1:30: Slowly pour water in a spiral motion until you reach about 60% of your total water weight.
  • 1:30-2:15: Continue pouring slowly, maintaining the water level in the dripper.
  • 2:15-3:00: Allow the water level to drop slightly before adding the final pour to reach your total water weight.

d) The total brew time should be around 3:00 to 3:30 minutes.

Tips for Pour-Over Decaf:

  • Use a slightly finer grind than you would for regular coffee to increase extraction.
  • Pour in small, controlled amounts to maintain an even extraction.
  • Adjust your pour rate based on how quickly the coffee is draining; slower for a finer grind, faster for a coarser grind.

Brewing decaf espresso can be challenging due to the beans' altered structure from the decaffeination process, but with the right technique, you can produce a delicious, concentrated shot.

Equipment Needed:

  • Espresso machine
  • Espresso grinder
