  1. Grind 8.25g coffee per bowl
  2. Place in cupping bowl
  3. Smell dry grounds (fragrance)
  4. Note aromas
  5. Prepare multiple bowls per coffee (3-5)

2. Add Water (Aroma)

  1. Start timer
  2. Pour 150ml water at 200°F
  3. Saturate all grounds
  4. Let steep 4 minutes
  5. Smell wet aroma

3. Break the Crust

  1. At 4 minutes, break crust with spoon
  2. Push grounds from surface to bottom
  3. Lean in and smell released aromatics
  4. Note intensity and character
