so i brewed up what will hopefully be a delicious imperial stout this last sunday. my wife's step-dad has been homebrewing for about 15 years. i knew fermentation was going to be strong and i didn't want my primary buckets lid to shoot off like it did a few years ago when i did a big stout. i've gotten in the habit of using a blow off tube which always does the trick. well, he told me that he didn't think a blow off tube would be able to sustain the fermentation with this one so he told me to throw a trash bag over the top of the bucket and put a rubber band around it (not too tight so gas could escape). i don't normally doubt what he says but i feel ill about this. i know the krausen has to be touching the top of the bag. am i looking at a good chance of having an infected beer when all is said and done?
