The Affordable & Perfect Solution For Keeping Your Beer Keg Cold Up to 12 Hours

As you may know, heat is one of beer’s big enemies. It can promote oxidation, which is what happens when natural compounds within the beer react with oxygen leading to off flavors in your beer. Heat can also result in flavor loss altogether, creating a bland product that is in no way reflective of the beer in its original state.

Whether you are a professional caterer or are just throwing an outdoor party for your friends, keeping your beer cold is critical to the success of your event. Ideally, beer will be served between 40 and 50 degrees F, but keeping beer cold on a hot summer day can be a challenge. Fortunately, even on the hottest summer days, the Powerblanket ICE insulated keg cooling blanket can keep a cold keg of beer below 50 F for up to twelve hours without ever having to change the ice packs.

The Importance of Temperature in Draft Beer Dispensing

Maintaining proper temperature is critical for dispensing keg draft beer effectively. Nearly all draft beer issues stem from temperature irregularities. Because most U.S. draft beers are unpasteurized, they require constant refrigeration—a challenge, especially during hot summer days.

The Effects of Temperature on Beer Freshness

Even a slight rise in temperature, such as half a degree above 38°F, can cause CO2 to escape the beer, leading to excessive foam and undesirable sour or cloudy flavors. Once the temperature exceeds 50-55°F, bacteria growth accelerates, spoiling the beer’s taste and appearance.

How Temperature Influences Beer Flavor and Aroma

Temperature profoundly impacts how we perceive beer’s flavor and aroma. Chemical compounds responsible for the variety of aromas and tastes we enjoy are either enhanced or diminished based on the beer’s temperature, making precision crucial for an optimal experience.

Powerblanket Controlled Experiment - Beer Temperature vs Time

We even ran a controlled experiment so you can see the data on the graph below for yourself. We started with a 40 F keg of beer. We wrapped the Powerblanket ICE insulated keg cooling blanket around the keg, placed it inside a 95 F environmental chamber and recorded the beer’s temperature for 24 hours. After 6 hours the beer was 43 F and had only increased 3 degrees, and after 12 hours the temperature had only increased 10 degrees to 50 F, which is still considered optimal temperature for consuming beer.
