So this is a first for me.... I made a starter out of some (actually a lot of) slurry from my last batch and 4 hours later the thing had blown the aluminum right off the starter and had a HUGE krausen! Here's what I did: sanitized some more foil and a measuring cup - scooped most of the krausen out, cleaned and recovered. I wouldn't be worried except it had blown the foil right off of it and was exposed... Do you think it poses a serious chance for infection or do doubt it since it was scooped off and didn't fall back in? When should I cold crash this? I was planning to brew on Monday night - should I just let it run til then?
