I have been making the same, or close to the same, recipe of strawberry blonde for several years now. I have always transferred 5 gallons on to 5lbs of strawberries. Since this is a wheat'ish beer, and I am not concerned with clarity, would it be ok to just add the frozen berries to my 6.5 gallon glass carboy? What about adding the berries to the primary after fermentation, letting them soak for a week or so, then transferring to a secondary to get it off the trub?
