restarting fermentation
« on: December 23, 2010, 07:43:30 PM »
Question . I  have a English style Barleywine that started at 1.080 and finished at 1.040 and obviously needs to be restarted as it should finish around 1.023.
I have racked to secondary and had to go out of town for a week or so and the carboy has been in the basement at cool temps  40-50's , by the way the beer is beutifully clear at this time.
Can I slowly warm the beer back up to room temp and repitch to restart and finish the fermentation or am I stuck with a tasty but overly sweet beer ?   ??? ???

1.080 is not that big of a beer and you shouldn't have a problem with it, but . . .

It sounds like you racked to secondary prior to the fermentation being completed.
This means you likely have a stalled fermentation.  The best fix is to warm it up to fermentation temp (mid 60's) and add a working population of yeast, figure about the amount that you racked it off.

Two ways,  First, get a growler of fresh active yeast from a friendly brewpub
second, make a small beer and pitch the yeast cake at 1 week.  No O2 addition.
