Bottled my first lager today and after capping the 6th bottle I realized I had not added a small amount of yeast to the bottling bucket. Thus, I added about 3 grams of yeast to the bucket and a very small amount to each of the capped bottles. I noticed that upon bottling this lager there were very many bubbles that seemed to be being released inside the beer. Is this typical? I had lagered this for 3 months and was bottling at a colder temp than room temp.
