Very Flat Beer

[westham111]

Can somebody help me please, i have put my pressure barrel in the shed and have found that the beer is flat, and very cold is this because of the weather being so cold at the moment and if so what is the best temp to keep the beer at many thanks Paul

When a brew is stored in a cold place, it absorbs more of the Co2 & this will be the cause of your flat brew. If you can, store it at around the 12c-14c range.

The temperature range you quoted is good for most ale yeasts, but the cause of flatness is incorrect. While it is true that beer absorbs more CO2 when it is cold, that would not make the beer flat, it would make it fizzy. The real cause of the beer being flat is that at the low temperature, ale yeast stops working. If you want to store beer at very low temperatures and keep it fermenting, use lager yeast, since it can withstand temperatures to 5°C, and it just slows down without completely stopping. Many lagers are conditioned at around 0°C, the yeast keeps working slowly, and they don't freeze because of the alcohol content.

If you bring it into a warmer place, and it does not carbonate, you can make a half-liter yeast starter with a pack of SafLager yeast, and dump that in, then wait a few days and you will have the carbonation you want.
