i made my first batch of beer, using a kit. all went well, fermentation started within 10 hours, and seemed to be going along great. now, sunday morning, (i made the beer on friday afternoon) there are no more bubbles in the air lock. how could fermentation be done in such a short time? i followed all the directions closely and I spent lots of time reading books on home-brewing before i even bought my supplies and kit. thanks/dweizel
