I usually start with the following approximate settings:
Aeropress usually start around 4-1
V60 usually ends up between 4-0 to 5-2 aiming for between 2min 30 and 3min30 draw down time.
Obviously each bean is different, but when I’m feeling lazy, Aeropress is almost always done at 4-1, and a 1 or 2 cup v-60 at 5-1
