I've done plenty of searching, but come up with too much variation on how to do a diacetyl rest for an ale.
The beer is an all-grain brown ale modeled and modified after Dogfish Head's Indian Brown Ale.
10 gallon batch, fresh smack pack (blew up fast), and a 3 day, 4 cup starter using LME.
Gravity at day 7 (today): 1.041
Now the gravity progression is one issue as I would expect lower, but I've had cooler temperatures in the garage. It was pitched at an equalized 73 F, and has maintained temps in the mid to high 60s.
During the gravity check I gave the carboys a good stir to get things moving again.
So what to do? I've read with ales that require a diacetyl rest the primary should be extended anywhere from 2 days to 3 weeks after fermentation has stopped!
- Wait xx days after activity has slowed to 1 bubble every 1-2 minutes.
- Attempt to warm up the carboys with uncontrollable brewer belts to ~75 F for a couple days after activity has slowed.
- Do a 'dirty' transfer to pull a lot of yeast into the secondary and bring them inside which will raise the temp in the high 60s.
Any suggestions are appreciated.
