I'm wondering if anybody has ever seen 1968 have the following behavior:
I pitched a 2 liter starter into a 1.060 brown ale. The fermentation temp was held at about 67F. Fermentation exhibited the usual vigorous activity for about 5 days then slowed way down. I checked the gravity, and it was still pretty high at 1.024, but the cap had fallen and the beer was pretty clear. I attempted to rouse the yeast once a day for the next few days by swirling the carboy. After a few days, I stopped rousing, but the fermentation continued at a slow rate, exhibiting an airlock bubble every 3 to 4 minutes. This went on for the next 2-3 weeks, with no noticeable change in activity. At some point I checked the gravity, and it had fallen to about 1.020. Now, in its fourth week of primary fermentation, activity has has suddenly ramped way up. There is a modest foam cap (bubbles mainly), and the airlock activity is back up to a bubble every few seconds instead of every few minutes. It's been doing this for 2 to 3 days now. I have never seen anything like this before. I have used this yeast about 4 times, and each time the fermentation process seemed different. The last batch fell to 1.017 within days. Any ideas? I'm hoping that I didn't infect it when I checked the gravity. The bucket of Star-San that I have been using is a little old and may be suspect.
