Typically, a standard long draw beer system does its best to keep the temperature of the beer the same at the walk-in cooler. When a blizzard beer system is installed, it does not matter what the temperature of the walk-in cooler is. You will still be serving 29° beer.

Most domestic keg beer must be refrigerated and should never exceed 50°F. When beer goes above this temperature, it can go through a secondary fermentation and will “kick”, which is commonly known as “wild beer”. The end result is a keg of beer which patrons will not want to drink. 

Serving the cold is beer has many advantages. The most significant advantage is satisfied customers. In addition to increased sales, serving beer colder than ice can one increase profitability by as much as 35% by eliminating “warm beer foaming”.
