Another thing I did today was grinding at a wrong grind size for filter. I have two grind settings for filter, which are #27 for manual brews like V60/Hario Switch and #17 for the Aromaboy on the Duo.
Without checking the grind size, I ground the coffee, and started brewing on the Hario Switch. Normally, 18g coffee and 270g water require 6 × 45g x 40s pulses for a total brew time of 4:30 mins for self. At the start of the 2nd pour, I realised the mistake, quickly adjusted the wait time between pours from 40s a pulse to 30s, reduced the dry bed time by a minute to 3:30 mins and ended with a very nice cup.
It happens to every one of us. I don’t like wasting coffee. I drink irrespective of the taste. 😊
