How Long Will a Growler Keep Beer Fresh?

A growler is a popular container used to transport and store beer. It typically holds 64 ounces (1.89 liters) of beer and is a convenient way for beer enthusiasts to enjoy their favorite brews on the go. However, one common concern among beer lovers is how long a growler can keep beer fresh. Let’s explore this topic in detail.

The freshness of beer in a growler depends on several factors, including the type of beer, the quality of the seal, and the conditions in which it is stored. In general, unopened growlers can keep beer fresh for up to two weeks when stored in a cool, dark place. However, once opened, the clock starts ticking, and the beer should ideally be consumed within 24 to 48 hours to preserve its flavor and carbonation.

To ensure the longevity of your beer, here are some tips:

1. Store your growler in the refrigerator to maintain a cool temperature.
2. Keep it away from direct sunlight, as UV rays can degrade beer quality.
3. Open the growler only when you’re ready to consume the beer.
4. Seal the growler tightly after each use to prevent oxidation and loss of carbonation.
5. Avoid shaking or agitating the growler, as this can cause the beer to go flat.
