Stuck Fermentation

wow i had no idea that the lower the mash temp the more fermentable the wort. I will make sure tho follow that when I do my next batch which has got 3lbs ot 2 row

I don't mean to be a jerk, but have you read any books on brewing--specifically, all grain?

There's plenty of good info to be had here, but to learn the basics you're going to have to do some reading.

Not to interupt but I just wanted to give an update on my initial post. The beer is great, a little lower on the gravity than what I wanted but none the less great tasting. A friend of mine tried a little out of the keg ( have not chilled it yet ) and stated that it was the best I have ever made. I now have a light Pilsner in the secondary that also was a little low on the ABV but that was an efficiency issue. Sparging and mash adjustment will be made on the next batch.

Thanks again for all of the help.

ok brewer heres what i think happened. the fermentation was stopped prematurely by something (maybe transferring to secondary) and then the yeast gegrew and began to eat the rest of the fermentable resulting in a carbonated beer. The reason I believe this to be the case is that the only time I see aitlock activity is when I roll the carboy and "shake" it up, it bubbles 5-10 times and then stops. I'll measure gravity in a few days and if its stable Ill bottle.

When yeast produces CO2, it gets absorbed by the beer first. If there is enough CO2 in the beer already, it will gas out and be visible in the airlock. When the beer is sitting still, it can even become oversaturated with CO2 and this CO2 will be released when the beer is splashed around.

Now the bubbles that you see may come from the extra CO2 that is released by moving the carboy. If you can do this everyday, and get bubbles every day, the yeast must still be active and produces CO2. In this case you should also see airlock activity (which might be very slow though).

So now it's a little lower gravity than you wanted?

Whatever, glad it turned out OK!
