I started an all-extract hefe three weeks ago today. Pitched a large starter (1/2 gal) from a previously harvested batch of Wyeast German Wheat #3333. Started explosively overnight, and has been fermenting in 65deg ambient temp (I know, the low end of the range) and is at 1.015 which is where I expect it to finish based on my previous 3 batches of the same recipe.
However, when I stole some in my thief to check the SG I noticed a lot of bubbles rising, as if it were still fermenting, though there has been no noticeable airlock activity for about a week and I can't see any activity in the carboy. Do I give it another week and see what happens, or should I go ahead and bottle it?
I was going to use the carboy for a lager I'm planning to start in a couple days but I do have a bucket I can use for that if I have to.
