I did, however, bow to the dictates of science and try to collect some objective data. My methodology was to take one of each beer, crack them, and pour them aggressively into a 22 oz. wheat beer glass, aiming for maximum head.
Results are as follows:
- 1/8 tsp priming sugar: 1/2" head
- 1/4 tsp priming sugar: 1 1/2" head
- 1/2 tsp priming sugar: 3" head (couldn't pour it all in right away)
Tomorrow morning, I plan to re-prime the rest of the hefes with 1/2 tsp priming sugar. Prost!
