I shouldn't expect much krausen and blowoff if I'm dryhopping in secondary, should I?
Looking back at my OP maybe it wasn't clear enough. I'll be fermenting 2.5 gallons in a bucket, and will rack to secondary for dryhopping. My concern is that dryhopping 2.5 gallons in a 3 gallon carboy secondary will leave too much headspace. Is this correct, or should I not be concerned?
