Hi,

Have a little problem - my beer has stopped fermenting, I need to achieve a SG OF 1.015 from an OG of 1.041

First few days went great bubbling and foaming top etc. however i thnk the cold got to it as when i went in on the thrid day the temp was about 10degrees celcius. now it has stopped fementing and has wont start back up again. I have warmed the wort to about 18DEGREES C and have swirled it to get back into suspension. anyone have any ideas what to do or whether its ruined?

Thanks

all grain brew by the way

Airlock activity is not a sign of Fermentation. I think you'll be OK if you had 2-3 days of active fermentation. I try to keep mine between 18 and 20C.
Take a reading after 7 days and see where you gravity is at if you get the same reading 3 days in a row, your beer is pretty much done.
