We're just about to enter the danger period, when the winter can cause larger swings in temp resulting in them dipping too low and causing stuck brews. Houses still have a bit of residual heat but from Nov-Mar I've had stuck brews, especially after Xmas.
I use a water bath comprising trug container from Wilko (http://www.wilko.com/laundry-baskets+truggs/wilko-laundry-trug-purple-40l/invt/0267567 ) and an aquarium heater, and cover it all with an old towel. Heater set to 20*C. I use about 2 galls water in the bath. No need to sanitize the water in the bath, since it will not come into contact with your brew (assuming your FV is not fitted with a drain valve, in which case a water bath may not be a good idea) .I use a water bath method with an aquarium heater and lcd underwater thermometer (both fleebay specials!). Seems to be doing the job.
Hi lads, I've been successfully brewing some beers using the Bain Marie method to maintain temperature. However I filled some bottles that tasted great and had some natural fizziness, but the rest of the brew I did in the fv and it is flag as anything and really not great to taste. Anyone know why this is and what I can do with the 'dishwater' I have in my fv?
