How Fast Should You Drink a Growler?

A growler is a popular vessel used to transport and store draft beer. It typically holds 64 ounces (1.89 liters) of beer and is commonly made of glass or stainless steel. When you purchase a growler filled with fresh beer from a brewery or taproom, it's important to consider the optimal timeline for consuming it to ensure the best flavor and freshness.

Understanding the Factors

Several factors contribute to the ideal consumption timeline for a growler of beer. These factors include the type of beer, the brewing process, the filling method, and the storage conditions. Let's explore each of these factors in more detail:

Type of Beer

Different styles of beer have varying shelf lives and flavor profiles. Generally, hop-forward beers such as IPAs are best consumed within a few weeks to a month to enjoy their vibrant hop aromas and flavors. On the other hand, malt-forward beers like stouts and porters can often be enjoyed for several months without significant flavor degradation.

Brewing Process

The brewing process itself can impact the longevity of a beer. Beers that undergo pasteurization or are filtered to remove yeast and other particles tend to have a longer shelf life. Unpasteurized and unfiltered beers, commonly known as "craft" or "microbrewery" beers, may have a shorter shelf life due to the presence of live yeast and other microorganisms.

Filling Method

The method used to fill the growler can also affect the beer's freshness. Ideally, the growler should be filled directly from the tap, minimizing exposure to oxygen and ensuring a tight seal. Some breweries use counter-pressure fillers or growler-filling machines that help maintain carbonation levels and reduce oxygen contact, resulting in a longer shelf life.

Storage Conditions

Proper storage conditions are crucial for preserving the quality of the beer in a growler. It is recommended to store the growler in a cool, dark place, such as a refrigerator, to slow down the aging process. Exposure to heat, light, and temperature fluctuations can accelerate the deterioration of the beer's flavor and freshness.

Optimal Consumption Timeline

Considering the factors mentioned above, it is generally recommended to consume a growler of beer within 3 to 5 days after it has been filled. This timeline ensures that you enjoy the beer at its peak freshness, with the flavors and aromas intact. However, some beers can still be enjoyable for up to a week or two if stored properly and kept refrigerated.


Drinking a growler of beer within the optimal consumption timeline allows you to experience the beer's intended flavors and aromas. Understanding the factors that contribute to the freshness and shelf life of beer can help you make informed decisions about when to enjoy your growler. Remember to consider the type of beer, the brewing process, the filling method, and the storage conditions to ensure the best possible drinking experience.

Frequently Asked Questions

Q: Can I drink a growler of beer after the recommended consumption timeline? A: While it is still safe to consume beer from a growler after the recommended timeline, the flavors and aromas may have deteriorated, resulting in a less enjoyable drinking experience.

Q: Can I extend the shelf life of a growler of beer? A: Storing the growler in a refrigerator and minimizing exposure to heat, light, and temperature fluctuations can help extend the shelf life of the beer. However, it is still best to consume it within the recommended timeline for optimal freshness.

Q: Can I reseal a partially consumed growler? A: It is not recommended to reseal a partially consumed growler as it can introduce oxygen and compromise the beer's freshness. It is best to consume the beer within a single session or share it with friends to ensure the best flavor.

Q: Can I transfer the beer from a growler to another container for longer storage? A: Transferring beer from a growler to another container can introduce oxygen and negatively impact the beer's freshness. It is generally best to consume the beer directly from the growler within the recommended timeline.

Q: Can I freeze a growler of beer to extend its shelf life? A: Freezing a growler of beer is not recommended as it can alter the beer's flavor and potentially cause the container to burst due to expansion. It is best to store the growler in a refrigerator for optimal freshness.

Remember, the information provided here serves as a general guideline, and it's always a good idea to check with the specific brewery or taproom for any recommendations they may have regarding the consumption timeline of their beers.
