One of the most important things in a beer cellar is temperature.
A UK beer cellar needs to be kept at a constant temperature of 12 degrees Celsius (53.6 degrees Fahrenheit) - 24 hours a day - 365 days a year.
This temperature can vary up or down by a degree or two but no more.
There are three very important reasons why your beer cellar temperature needs to be at a constant 12 degrees Celsius - (53.6 degrees Fahrenheit).
Reason 1.
If you sell cask beers in your pub, club or bar then these need to be kept cold or they will go sour very quickly and taste of vinegar.
However we can’t make cask beers too cold or they suffer from a problem called ‘chill haze’ - this makes the beer in your pint glass look hazy and unappetising.
12 degrees Celsius (53.6 degrees Fahrenheit) is the perfect balance between keeping your cask beer fresh and not having ‘chill haze’ problems.
Reason 2.
If you sell keg beers then the temperature needs to be kept constant - this is because your Brewery Engineer sets gas pressures for your keg beers and these gas pressures are fixed according to your cellar temperature - if your cellar temperature goes up and down like a yo-yo then it makes it impossible for your Brewery Engineer to fix the pressure correctly!
Reason 3.
Keg beers flow through additional cooler gadgets on the way to the beer taps on the bar and these additional cooler gadgets only work properly if the beer flowing into them isn’t warmer than 12 degrees Celsius.
