What is a glycol beer system?

Answered by Frank Schwing

A glycol beer cooling system is a type of draft beer system commonly used in bars, pubs, tap rooms, and restaurants to keep draft beer at a consistently cold temperature from the walk-in cooler to the dispensing tower. It relies on the use of a specially formulated glycol solution to chill the beer lines and maintain the desired temperature.

The glycol system consists of several components that work together to ensure the beer remains cold and refreshing. First, there is a glycol chiller, which is a refrigeration unit that cools the glycol solution. This chiller is typically located in the walk-in cooler or a nearby equipment room.

The glycol solution is then circulated through insulated beer lines that run from the chiller to the beer tower. These lines are usually made of stainless steel or food-grade plastic and are designed to minimize heat transfer and maintain the cold temperature of the beer.

To keep the beer lines properly chilled, the glycol system utilizes a pump to circulate the glycol solution. The pump continuously moves the glycol through the lines, preventing any warm spots or fluctuations in temperature. This ensures that the beer is consistently cold from keg to glass.

In addition to the chiller, beer lines, and pump, the glycol system also includes various fittings, valves, and temperature control devices. These components help regulate the flow of glycol, monitor the temperature, and maintain the desired coldness of the beer.

One of the main advantages of a glycol beer cooling system is its ability to maintain the desired temperature over long distances. This makes it an ideal choice for establishments with long beer lines or multiple dispensing towers. The use of glycol ensures that the beer remains cold and fresh, even when it has to travel a significant distance.

Another benefit of glycol systems is their versatility. They can be customized to fit the specific needs of different establishments. Whether you have a small bar or a large restaurant with multiple beer towers, a glycol system can be designed and installed to meet your requirements.

From a personal standpoint, I have experienced the difference a glycol system can make in the quality of draft beer. When I worked at a busy pub, we had a glycol cooling system installed, and it made a noticeable improvement in the taste and consistency of the beer. The customers were happier with the cold, refreshing draft beer, and it helped us maintain a high level of customer satisfaction.
