Thanks, I will definitely have to keep you guys posted. It has only been in primary since Friday and I plan to bottle it up after 14 days. I apparently didn't need a blow off for this stout, but to be safe, last night when I opened it it was fermenting like crazy, but since it didn't violently ferment like the RIS than I did a blow off for nothing. I don't however believe that it hurts anything, as a lot of folks actually talk about fermenting without a lid.
