What Is a Beer Growler?

A beer growler is a refillable container used for storing and transporting draft beer, cider, kombucha, or any other brew.

How to Fill a Beer Growler Properly

To fill a beer growler like a pro, start with a clean, chilled growler to reduce foaming. Hold the growler at a slight angle, around 45 degrees, while filling to minimize foam buildup. Pour slowly, letting the beer flow along the inner wall of the growler. Leave about an inch of space at the top to allow for proper carbonation.

After filling, tightly seal the growler with its cap to keep the beer fresh. Store it upright in a cool, dark place or in a refrigerator if possible. Avoid shaking or tilting the growler to prevent excessive foaming. Drink within a few days for the best flavor and freshness.

Frequently Asked Questions

Do You Need a Headspace When Refilling a Growler?

Yes, you need to leave at least 5% headspace when refilling a growler. This small space allows the beer’s carbonation to expand without building too much pressure. Without headspace, the beer may lose freshness or spill when opened. A little room at the top helps keep the beer tasting great.

How Long Does Beer in a Growler Last?

Beer in a growler typically lasts about one to two weeks if unopened and refrigerated. Once opened, it’s best to drink the beer within 24 to 48 hours to enjoy its full freshness and carbonation. After that, the quality may decline quickly. Freshness depends on storage and how well it’s sealed.

Can You Chill a Growler?

Yes, you can chill your beer-filled growler by placing it in a refrigerator. To chill the growler, place it in the refrigerator for 15-20 minutes before serving. This helps enhance the beer’s refreshing and crisp qualities, providing an optimal drinking experience.

Conclusion

A beer growler is a convenient way to store and transport draft beer, keeping it fresh for a short period. Whether made from glass, stainless steel, or ceramic, growlers are designed to preserve flavor. They are perfect for sharing craft brews. Just remember to drink it within a few days.
