yeast stalled?
 
Hi,
well, this is my first post, and probably my 5th or 6th batch.... i brewed a stout late friday (a guiness clone) pitched the yeast before i went to sleep and by morning things were raging and bubbling and generally looking good. i opened up the fermenter to take a look saturday evening, had a nice firm head forming, temp was 78 degrees F and i was pleased, until sunday afternoon that is - i think the yeast have stalled out considerably, the airlock bubbles only about once every 25-30 seconds now and i'm getting a little worried, and the batch reached at least 82 degrees. i've put it in a cooler place and its since dropped back down to 78, tho i'd like to get it cooler still.
i guess my question is, do you think this batch is a goner? is there any way to re-envigorate the yeast, or could i pitch another package in there without worrying? and more the point, any ideas why this happenned? was it just the heat or should i have not openned up the ferment bucket?
thanks in advance for any help/advice,
dan wolfe

Take an SG reading if you can...could be your fermentation is almost done.

really? in 2 days? i don't have the numbers on hand right now (at work) but its a 5 gallon batch with over 6 lbs of extract + the grain/malt...
not that i don't believe you, this is my first go at a batch of stout. ;)

and just to add some info, i just used the dry yeast that came in the kit

thanks again for the help :)

With a fermentation temp that high, it is likely that it is done already. Like Pistolero said, take a gravity reading. I think you'll find that it has completed fermentation.

Great! thanks guys, you've eased my mind for the day :)
I'll check it as soon as i get home and with a little luck i'll get to rack it and maybe even start a new batch of something else. does anyone use corny kegs as a secondary? I've got a couple 'extra' for a few weeks (until i can get more beer brewed) and was thinking the SS would be perfect and i could just use some hose and a milk jug as a make shift airlock.

I'll update the thread tomorrow or later tonight with an SG reading if the yeast are still as slow as they were yesterday.
thanks again!

alright! skipped outta work a little early to check things out :)
SG's all the way down to 1.018 (at 74 degrees now), so i'm thinking its time to rack it....sound about right?

Some will say now, some will say wait a couple more days. I say...Just feel the beer kneemoe. You'll know what to do :cool:

LOL, it tastes about right -na-na-na-na :D (for an unaged beer)
thanks a bunch for the helping hand :)

I say rack it. You'll get another short round of fermentation in secondary and the gravity should drop a touch more. Bottle or keg when you get around 1.010 or so.

Whats the FG supposed to be? It is a stout, so 1.018 could be right on the money...just depends on the recipe.
