when you guys cold crash, do you switch to tinfoil on the carboy mouth?
i just cold crashed an ipa while leaving the blowoff tube on and came back to my fridge a day later to realize i had just siphoned 800ml of starsan into my beer.
i guess it makes sense as the diff in temps (inside carboy compared to ambient) would cause a vacuum effect.
oh well, bumped up my volume and the beer tastes great.
