I started a Pumpkin Ale the other day. It was going strong and I could visibly see bubbles going through the airlock. But all of a sudden it stopped. I don't think it should be done though but it is the first time I tried using ale yeast. The initial hydrometer reading was 1.049 so it can't be done, can it? I'm worried because it smelled really good and I would love to be able to drink it. If anyone has any suggestions please let me know.
