How Big Is a Growler of Beer? Unveiling the Standard Size
A growler of beer is typically 64 fluid ounces in the United States, which is equivalent to one-half gallon or roughly four pints. Smaller “growlettes” are also available, generally holding 32 fluid ounces, or about two pints.
Introduction: The Growler’s Rise to Prominence
Growlers have become a staple for craft beer enthusiasts, offering a convenient and relatively affordable way to enjoy draft beer at home. They represent a direct link between the brewery and the consumer, fostering a sense of community and allowing access to limited-release or taproom-exclusive brews. Beyond their functional purpose, growlers have evolved into collectible items, often adorned with brewery logos and artwork.
Understanding Growler Capacity: Standard vs. Variations
While the standard growler size in the U.S. is 64 ounces, variations do exist. These deviations are often marketed as “growlettes,” “mini-growlers,” or simply by their specific volume. It’s crucial to check the marked capacity of any growler to ensure you’re getting the intended amount of beer.
- Standard Growler: 64 fl oz (1/2 gallon, ~4 pints)
- Growlette (Mini-Growler): 32 fl oz (~2 pints)
- European Growlers: May use metric volumes (e.g., 1 liter, 2 liters), requiring conversion.
Materials and Design Influences on Size
The material from which a growler is made – glass, stainless steel, or ceramic – doesn’t directly impact its standard size. However, the design may subtly influence the perceived size and weight. Stainless steel growlers, for example, are often favored for their durability and ability to maintain beer temperature, sometimes leading to a slightly different form factor compared to traditional glass growlers. Double-walled insulation also impacts the external size.
Filling and Maintaining Your Growler
Properly filling and maintaining a growler is critical for preserving the beer’s quality and ensuring a positive drinking experience. Most breweries have specific procedures to minimize oxygen exposure during filling.
- Purge the Growler: Request that the brewery purge the growler with CO2 before filling to remove any residual oxygen.
- Proper Seal: Ensure the cap or closure creates a tight seal to prevent carbonation loss.
- Refrigerate Immediately: Store the filled growler in the refrigerator to maintain its temperature and slow down the degradation process.
- Consume Promptly: Drink the beer within 1-3 days of filling for optimal freshness.
Common Mistakes and How to Avoid Them
Several common mistakes can compromise the quality of beer stored in a growler. Understanding these pitfalls can help ensure you enjoy your draft beer as intended.
- Letting the Beer Warm Up: Exposure to room temperature can accelerate oxidation and staling. Always keep your growler refrigerated.
- Improper Cleaning: Residue or bacteria in a growler can contaminate the beer. Thoroughly clean and sanitize your growler after each use.
- Delaying Consumption: While refrigerated, growlers are not meant for long-term storage. Consume the beer promptly to avoid it going flat.
- Ignoring Brewery Filling Practices: Trust the brewery’s procedures for filling growlers. They are experts in maximizing the beer’s lifespan.
Growler Types and Sizes Comparison
Here’s a table comparing the common types of growlers and their capacities:
| Growler Type | Material | Capacity (fl oz) | Capacity (Gallons) | Approximate Pints |
|---|---|---|---|---|
| Standard Growler | Glass, Steel | 64 | 0.5 | 4 |
| Growlette (Mini) | Glass, Steel | 32 | 0.25 | 2 |
| Large Growler | Glass, Steel | 128 | 1 | 8 |
| European (Metric) | Glass, Steel | Varies | Varies | Varies |
Frequently Asked Questions (FAQs)
Does the material of the growler affect how much beer it holds?
The material (glass, stainless steel, ceramic) doesn’t typically affect the stated or designed capacity. The standard growler is 64 oz, regardless of the material. However, differences in wall thickness or insulation might slightly alter the external dimensions and weight of the growler.
Are growlers legal in all states?
Growler legality varies by state and sometimes even by county. Most states allow growler sales, but some may have restrictions on where they can be sold (e.g., only at breweries) or how they can be filled. Always check your local regulations.
How long does beer typically last in a growler?
Beer in a properly filled and sealed growler, stored in a refrigerator, typically lasts for 1-3 days. After that, the beer will likely begin to lose carbonation and flavor. Immediate refrigeration is key to prolonging freshness.
Can I fill a growler with anything besides beer?
While designed for beer, growlers can technically be filled with other beverages. However, be mindful of the beverage’s carbonation level, as excessive pressure can damage the growler. Cleaning the growler thoroughly afterward is crucial to prevent flavor contamination.
How should I clean my growler?
Clean your growler immediately after emptying it to prevent the buildup of residue. Use warm, soapy water and a bottle brush to scrub the inside. Rinse thoroughly and allow it to air dry completely, upside down, to prevent mold growth.
What is a “crowler,” and how is it different from a growler?
A crowler is a large can (typically 32 oz) filled with beer at the point of sale. Unlike a growler, a crowler is designed for single use and cannot be resealed. Both offer draft beer to-go, but crowlers offer a more convenient, pre-packaged option.
Are there any environmental benefits to using growlers?
Using growlers helps reduce waste compared to purchasing individual cans or bottles of beer. It promotes refillable containers and minimizes the need for packaging materials, contributing to a more sustainable consumption model.
Can I bring my own growler to any brewery for a fill?
Most breweries will fill growlers brought in by customers, provided the growler is clean and in good condition. However, some breweries may only fill their own branded growlers. It’s always best to check with the brewery beforehand.
What is the ideal temperature for storing a filled growler?
The ideal storage temperature for a filled growler is in the refrigerator, between 35-40°F (2-4°C). This helps maintain the beer’s carbonation and prevents rapid degradation of flavor. Avoid storing growlers at room temperature.
What are the risks of using a damaged growler?
Using a damaged growler (e.g., chipped glass, cracked seal) poses several risks. The growler could break under pressure, causing injury. A compromised seal can lead to carbonation loss and beer spoilage. Never use a damaged growler.
Why is it important to purge the growler with CO2 before filling?
Purging the growler with CO2 displaces the oxygen inside, which is a major enemy of beer freshness. Oxygen can cause oxidation, leading to stale flavors and a shorter shelf life. CO2 purging significantly extends the beer’s quality.
Do insulated growlers keep beer carbonated longer?
Insulated growlers, especially those with tight-fitting seals, can help maintain beer carbonation longer by preventing temperature fluctuations. Temperature changes can cause the beer to release CO2, resulting in a flatter taste. The better the insulation, the longer the carbonation will last.
