I always pitch 2 full packs. Typical OG is 1.068-1.072. I don’t like underpitching.
Pitch at 70, hold at 70 for 4 days, bump up to 71 for 3 days, 72 for 3 days, then drop to 60 for 24 hours. Dry hop at 60 for 3 days. Transfer, carb, serve. This yeast performs beautifully if you follow this schedule.
