How does everyone keep there brews at the correct temps? my house is pretty erratic for temperatures and the nights are still pretty chilly.
Looking around it seems a fish tank heater would be the easiest and cheapest solution. There is one on the high street for £10, 100w, but all the pictures i find of them show the temp gauge starting at 20 degrees, i was under the impression 18 was the ideal number so are these appropriate?
21-27 for my coopers cerveza. Mine held that heat for 2 days and is down to around 18c now. It's still going but I figure it will take twice as along to finish as an estimate.
Next time I do one with lower household temps (next winter) I will do what someone else on here did and put the FV in another bucket and heat the water around the bucket with a fish tank heater
If i'd thought about it better I would have started it in an upstairs room as that's usually a couple of degrees hotter in my house.
