I was given a Mr Beer kit for Christmas and have been loving it, but want to expand my wings. I have gotten my hands on a 5 gallon carboy I will be using as a primary and am curious what others have experienced with using this size for primary. I am concerned about blow-offs. Would I be able to ferment 5 gallons in here without too much trouble, or would I be better to modify my batch size to 4 gallons?
