Temperature control is a very important aspect of successful beer brewing. It is one of the most important parts of maintaining quality and taste in beer. During the brewing process, it is not only important to have the right temperature; it is also important to make sure that this temperature is closely monitored and remains consistent. To find out what the optimal temperature is for the specific type of beer you are brewing is, you should refer to the instructions which came with your brewing kit. You can also find more specific information on the Internet. The optimal temperatures depend on whether you are brewing lager or ale and other things.

Step 1 – Using a Fridge or Freezer for Cooling

Ideally, you should have a fridge or a freezer which is specifically designed for brewing. If you don’t have one, almost any old fridge or freezer can be adapted to use for brewing. The only requirement is that the fridge has a functional temperature control feature in it. The fermentation tank should then be placed inside the fridge. A fridge is normally more appropriate than a freezer.

Set the temperature as according to the specific recipe for the beer that you are brewing. As a general rule, lager should be stored at anything between 40 and 55 degrees. Ales should be stored at typical basement temperature. If you are brewing ale, it is generally not advisable that the fermentation tank be placed in a fridge or a freezer unless the ambient temperature is very high.

To make sure that the beer is maintained at the right temperature all the time, check it several times per day. You can use a special brewing thermometer to check the temperature. Adjust the temperature control of the fridge or freezer as required.

Step 2 – Using Ice

Find the coolest area in your home, ideally the basement. The fermenter which contains the beer should then be placed into a fermentation vessel. This vessel can be any tub large enough to accommodate the fermenter. Place water and ice around it. Find the optimal temperature and add ice as often as required. Using the previous method is far more efficient, but using ice is the only option if you do not have a spare fridge or freezer at your disposal.

Step 3 – Increasing the Temperature

In most cases, you won’t ever have to attempt to warm the beer, though in some situations, it is necessary to regularly maintain a higher temperature for brewing ale. In this case, you will need to maintain a consistently higher temperature to get the best results. For ale, a temperature of around 70 degrees is normally optimal. To warm the beer enough, wrap the fermenter up with blankets or any other insulation material until it reaches the temperature recommended in the recipe. As in the previous steps, monitor the temperatures regularly.
