How Long Does Beer Last in a Kegerator? Tips for Fresh Beer Always


Kegerator is a combination of two words: Keg and refrigerator. A kegerator is a keg refrigerator and dispenser that keeps your beer cold, fresh, and convenient to draw. The beer kegerators come in different sizes and shapes to preserve beer’s freshness for a long time and to minimize waste.

In this article, we shall learn different aspects of a kegerator and how long does kegerator beer last. Keep reading.

How Long Is Beer Good in a Kegerator?

The answer to this question varies depending on factors such as the beer style, proper temperature, and the type of pump. Also, the type of beer determines its longevity in the kegerator. For instance, pasteurized beers will remain fresh for about 90- 120 days, while non-pasteurized beers remain fresh for about 45- 60 days.

The recommended temperature of a kegerator should be about 38 degrees Fahrenheit. If temperatures exceed 50 degrees Fahrenheit, the beer starts to grow bacteria and spoils quickly. Low temperatures will freeze the beer. Ensure you are storing your beer at the proper temperature to avoid losses.

Understanding The Factors Affecting Beer Freshness

How long is beer good in a kegerator? Three major factors affect the shelf life of beer in a kegerator. Understanding these factors helps you store your keg properly to keep it fresh and flavorful. They are:

1. Temperature

The temperature highly determines how long beer can stay fresh. What are the recommended temperatures to store your keg? The answer to this question is temperature between 2 to 4 degrees Celsius (36 and 40 degrees Fahrenheit). Higher temperature accelerates the aging of the alcohol, leading to reduced shelf life and loss of flavor. Ensure your keg stays fresh by maintaining the recommended temperature of the keg refrigerator.

2. Oxygen Exposure

Exposing your keg of beer to oxygen causes oxidation, which causes staleness of flavor and shortens the shelf life. Seal the keg of beer completely to cut off the oxygen supply in the beer. Also, ensure the keg is pressurized, and there are no leaks.

3. Carbon Dioxide Levels

The carbon dioxide level plays a crucial role in preserving the beer’s shelf life and flavor. The ideal level of carbon dioxide depends on the beer style. Check the carbonation guidelines provided by the brewery. Over-carbonating causes excessive foaming, reduces the shelf life of the beer, and alters flavors.

4. Light Exposure

Another factor that determines how long beer can stay fresh is light exposure. Exposure to UV rays causes beer to develop an unpleasant flavor caused by the light and hops reaction. Store the keg of beer in a dark area to prevent this.

5. The Beer Styles

There are different beer styles, each with a varying shelf life. Lighter and low-alcohol content beers have a shorter shelf life than deep-colored, stronger, and robust beers. The alcohol content and hop in stronger beers act as preservatives. Consider the type of beer and its characteristics to help you determine the shelf life.

Signs That Beer in Your Kegerator Has Gone Bad

Beer can remain fresh for weeks to months in a keg refrigerator. As discussed above, several factors can affect how long beer stays fresh. Preserving the beer under favorable conditions and consuming it within the recommended period is best. Here are signs that your beer has gone bad in the kegerator.

signs your beer kegerator has gone bad

1. Change in Taste and Aroma

The taste and the smell of beer will change if exposed to UV rays or oxygen or if it is expired. Stale beer will smell skunked, depending on the cause of degradation. Sometimes, if the beer is expired, it will taste like apple or mowed grass, indicating the presence of acetaldehyde in the beer. The skunky smell is due to the growth of bacteria in the beer due to exposure to high temperatures. Check the expiration date before consuming the beer.

2. Cloudiness or Sediment

A dusty or cloudy appearance of your beer indicates it is spoilt. The cloudy appearance means the yeast formation breaking down the beer. The beer can also change color to golden brown. However, the cloudiness sometimes means the beer has gone bad, but it will likely have a flat taste.

3. Altered Carbonation Levels

The lack of white foam when pouring beer indicates that the beer has gone bad or stale. The lack of carbonation means expired beer, over-chilling, exposure to high temperature, or oxidation.
