Dawg...I picked up a 5 gal recipe over the weekend. I measured out 2.5 gallons in my LBK and damn near goes to the top. Is there enough overhead with 2.5 gal in there to allow krausen without a keg explosion? Or can I probably expect an overflow? I will just have to find out I guess. Or.....use 40% of everything for the recipe, but I don't want leftover stuff I have to store. I just want to make it and if I like it, make it again, or mod it.
