I brewed 11 gallons of wheat beer (SG = 1.061) which was placed in a 6 gallon and 6.5 gallon bucket, very little headspace in either bucket. I made a 2 step yeast starter of WLP001 and added an extra pack of yeast to ensure I had adequate cell count and split the yeast between the two buckets. Beer is fermenting at 69 degrees F. I checked it this morning and the airlocks already had pretty decent activity, only 8 hours after pitching. I'm thinking about rigging up blow off tubes on my airlocks after work today to prevent a disaster, any thoughts? Thanks!
