I'm guessing that anythings possible but here's the story.
Boiled yesterday and put the beer in my Ale Pale. Shoved the blow off valve in the top of the bucket and let it set downstairs. Went downstairs at about 2:00 PM today and saw the blow off had came off, guess I didn't shove it in there good enough. Tried putting it back and shoved the small rubber gasket into the beer. Transferred the beer to my glass carboy and put the plug on since I could not seal the Ale Pale until I got that gasket.
May have had an opportunity to get infected, but I am hoping not.
I eat the stuff at the bottom of a carboy for breakfast!
