How to maintain the correct cellar temperature

Now that many bars, pubs and hotels are up and running after various lockdowns, it is important to do everything you can to ensure the success of your beer dispense system. One key way of facilitating this success, is ensuring you maintain the correct cellar temperature.

Importance of correct cellar temperatures

If your beer is not stored at the correct temperature then many issues can occur which can cause you to either serve below standard beer or experience an increase in wastage, both of which cost you money. With real ales, temperatures above 13ᵒC will have an adverse effect on the secondary fermentation process, causing a vinegary taste to the beer. In keg beer it can lead to an increase in fobbing, making it harder to pour and increasing wastage yields. Conversely, temperatures below 10ᵒC can slow down the fermentation process which in turn impacts upon the final taste, leaving beer not tasting as it should do.

Cellar temperature maintenance

Cellar cooling systems are generally split into two parts, the cooler and the fan. Here are some useful tips to ensure you maintain the correct cellar temperatures:

  1. Install a few thermometers in the cellar, keeping a record of the temperatures in different parts. If you are experiencing hot spots or uneven readings, it may suggest your cooler is not working as it should do. If this is the case, get it checked out by a qualified engineer and ensure you commit to regular servicing of the system.
  2. Avoid putting anything in the cellar that generates heat. Too many cellars house fridges or freezers to store food but these are all sources of heat and can impact the ambient air temperature.
  3. Vent the cellar for about 10 minutes every day but ensure the door is closed afterwards and left closed as much as possible. Coolers have to work hard when there are differentiations in temperatures, which can add to your energy costs.
  4. Clear Brew, beer line cleaning professionals, always check cellar coolers to make sure there isn’t a build-up of excessive ice around the cooler. This is a practise you should build into your cellar checks.
  5. Similarly check for dust and debris that may be collecting on the metal safety bars or cooling fins. If there is evidence of this, use a soft brush to remove.
  6. Avoid stacking food boxes or other items, that could potentially block the air flow around the cooler.
  7. Do not turn off the cooler overnight. This can often be a false economy, as the units use a lot more energy to get the cellar back to the correct running temperature and are placed on constant unnecessary strain.
