The fermentation temperature that you ferment beer, wine or cider at is critically important. A constant temperature is the most important factor, you don’t want large fluctuations in temperature, some people have poor results because they ferment in garages and sheds without a means of controlling the fermentation temperature. I say again the temperature you ferment at is critical!
So if you have to ferment beer, cider or wine at home what is the best way to control temperature?
A heat belt or heat pad is a relatively easy and inexpensive way to maintain a constant temperature, many all grain brewers build themselves a little fermentation chamber with a heat tube, these can be as simple as some insulation boards and an inkbird or ITC1000 attached to a heat tube, if you want to make lagers or ciders you may want to ferment at say 10 degrees, so you will need a cooling aspect (Fridge) to the set up also.
So how is this acheived?, its again a fairly simple process, usually the brewers use a second hand fridge and add a dual temperature controller, so you plug the fridge into the dual temperature controller and place a heat tube inside and plug it into the other plug outlet on the dual temperature control and set the temperature on the digital display.
Mangrove Jacks have designed a Dual Temperature Controller and we feel its the best solution on the market currently, it doesn’t require and DIY wiring and its safe and tried and tested. It can be used with a fridge set up, heat pad or heat belt. The fridge and the heating option can be plugged into the controller at the same time allowing them to work in partnership. There is no additional wiring or probes just plug it in.
Pay attention to recommended fermentation temperatures, you will have great success if you can control what temperature you can ferment at, take a Wheat beer for example if you use a good quality wheat yeast like Munich Classic from Lallemand and you ferment it at 17 degrees it will produce beautiful banana notes, take the same yeast and ferment it at 23 degrees, it changes and becomes spicy and has more notes of clove. The ability to control temperature will hugely improve your beers, ciders and wines.
A constant temperature is critical and will make big differences in the quality of your homebrew
