    I've homebrewed with friends a few times, but nothing major. I brewed the Northern Brewer Imperial Stout kit last week and pitched using White Labs Edinburgh Yeast.

    OG was 1.094

    After several days of aggressive fermentation, it has now been one weeks since brew date. The past few days the visible fermentation out of the airlock has has slowed to a crawl. I haven't seen a bubble in the past day or so.

    The gravity is now 1.35

    Is this stalled fermentation? Or do I just need to sit and wait? I know I've seen people to say to sit on it for a month. Also I'm wondering when would be a good time to transfer to the 5 gal White Oak barrel I'm going to age it in.

    Thanks!

    Wait three days and check the gravity again. There's no other way to know if fermentation has ceased. BTW, Did you make a yeast starter?

    No. Tossed the vial in, went crazy and krausened up into the airlock for a few days though.

    um, isn't the gravity supposed to go down? did you miss a zero? otherwise, your wort is getting more dense.

    Hah. Yes. 1.035

    Okay. One vial is really not enough yeast for optimal fermentation of a 1.094 wort. You still made beer, and it may still be fermenting (airlock bubbles are not a good quantitative indicator), but under-attenuation (if that's what's happening) is a potential symptom of underpitching. Again, you'll really just need to wait a couple days and see. What was your expected FG, per the kit's instructions?

    I'll check again in a few days on the gravity.

    I can't find anything on the instructions about the final gravity, but a quick search through their forums and google reveals most people are getting between 1.023 and 1.032 before racking to secondary.

    bummer. i was hoping you just invented some sort of new beer "cheese" like substance.

    I do have a dry yeast pack of Safale US-05 that came with another kit. The beer I tasted after taking the Hydrometer readings though tasted pretty fine. Not very sweet.

    Also, I may have been generous on the hydrometer. its 1.030 to 1.035

    Beese.

    If it's at 1.030 and you started at 1.094 it sounds reasonably finished at 8.4% ABV. In the future, get yourself a erlenmeyer flask and some DME and do a starter.

    Ok thanks.

    A bit if info I left out. I added honey and molasses to the boil. Are these non fermentable?

    Stop. Put down the hydrometer and back slowly away from the fermentation bucket. Do not attempt to reach for any more equipment. Do not attempt to open the lid on this beer again.

    1 week isn't enough for ANY beer in my book, let alone a first batch 1.094 imperial stout. Never open your fermenter till at least two weeks have passed. Then at best do a gravity check with a sanitized wine thief, checking it again in three days. Better yet, for a high gravity stout, two weeks is still too short of a time. Beer is about patience, and noobs don't have any. While the beer may have reached FG, the yeast are still cleaning up the by-products of fermentation (and they're still probably busy, since you probably under-pitched).

    You must learn patience, Luke, you must feel the force around you.

    No. All of the sugars in honey are fermentable. Molasses also contains fermentable sugars.

    I think for someone doing their first beer, it's good advice, but if you pitch the right amount of yeast, aerate properly, and have temperature control, waiting 2 weeks to check your beer, and then another 3 days is kind of a waste. Most of my brews are in the 5% range, and at 3 days fermentation noticeably slows down, and is done at 4 days. Depending on how much time I have, I'll check the gravity and taste it at 5-6 days, then cool it for a week or so and package when I have the free time. I like to go open up the fermenter as little as possible, so I guess I don't see the point of making multiple gravity measurements (I'll make a final one during bottling as well).

    As far as the OP goes, I would say that doing an imperial stout (or imperial anything) as your first brew is kind of bold. On the one hand, off-flavors may be masked, which will be good. On the other hand, if the beer turns out not so well, drinking a batch of bad high gravity beer is a lot harder than drinking a bad batch of a 5% porter, brown ale or pale ale. If you want to do a really good big beer, you should probably make sure you have a good grasp on fermentation and sanitation; listening to the Jamil show on the brewing network is a good place to get a lot of info on it relatively quickly and painlessly.

    I agree that an Imperial Stout isn't really a newbie beer. But at least he didn't put a pumpkin pie in it.

    Or attempt spontaneous fermentation on a used turkey basting pan.

    Leave it as mentioned, also that yeast can take a while to finish on a more normal gravity beer, let alone a big one like that

    In the future, if you brew a beer over 1.08 OG it helps a lot to aerate it again 12-18 hours after pitching for about 30 sec with pure O2. Thicker wort puts more stress on your yeast and they will use up almost all the available oxygen in the initial growth phase.

    Thanks guys. I understand its not really a great idea to jump head first into anything. I just can't think of anything I'd like to brew more than an Imperial Stout.
