So I had a batch of IPA lose hop flavor and smell, I mean all of its hop flavor and smell after cold crashing my beer in the fridge for 3 days. When I checked on the beer on the 3rd day the air lock had almost all of the vodka sucked out of it into the beer and it was super frustrating. So, my question is, how can you lower the temp on your beers while in a fermenter without having this occur. I almost took my first stab at making a lager last weekend and I am fairly intimidated now. I use a 3 piece air lock for everything by the way.
