I've moved the brew into a casket after the initial 4 days after seeing that the overall yeast had nearly stopped working. The cask is pressurized as expected from the CO2 (now @10 days). However I think I let the cask to cool down over a period of 4 days when I went off for a few days, so the FG is only just above the red on my hydrometer.
Would putting the cask back into a warmer spot, start fermentation off again, with the residual yeast left in the beer? The reading before fermentation was 1.030 and is now showing 1.010, or just 2 notches above the red band, which If I'm right works out as a .020 difference making the alcohol level at 2.6%.?
If I see little to no change, can I restart the fermentation, or like said in an earlier thread, just sup it as a low alc brew?
