Wholesale Beer Growlers

A beer growler is a container used to store and transport beer. It typically has a secure, airtight lid to maintain the freshness and carbonation of the beer.

To clean a stainless steel growler:

1. Rinse it immediately after use to avoid beer residue drying inside.
2. Use warm, soapy water and a bottle brush to scrub the inside. Focus on the neck and bottom areas where residue may stick.
3. For stubborn stains or odors, use a mixture of baking soda and water, or a vinegar solution, then rinse thoroughly.
4. Dry it completely with a clean towel or let it air dry.

Yes, beer can go bad in a growler, especially if it is not sealed properly or if it is kept for too long. Exposure to oxygen and changes in temperature can cause the beer to oxidize and spoil. This will cause a flat taste or going vinegary.

Yes, if you want to preserve the beer’s freshness and carbonation, it should be refrigerated. But don’t put it in the freezer.

Keg: A keg is a larger container, typically ranging from 5 to 15 gallons, used for storing and dispensing beer in bulk. Kegs are commonly used by breweries, bars, and restaurants, and they require specialized equipment (like a tap system) for pouring.

Growler: A growler is a smaller, portable container, usually between 32oz and 128oz, used to transport beer from a taproom or brewery. Growlers are designed for personal or small group use and are sealed with a cap to keep the beer fresh.

Beer growlers are most commonly made from 18/8 stainless steel, glass, and ceramic. Stainless steel is popular for its safety, insulation properties, sustainability, corrosion-resistance, and durability.

Beer can at least last 1–7 days in a growler. If sealed properly and kept in a cool place, it may stay good for 2 weeks. However, several factors can impact its shelf life.

(1) Storage:

• Cold Storage: Beer should be kept at a cool, consistent temperature (ideally in a refrigerator at 38°F / 3°C). This helps to slow down oxidation and preserve carbonation.
• Room Temperature or Warm Storage: Storing beer at room temperature can accelerate spoilage, making the beer flat more quickly.

(2) Type of beer:

• Light beers (like pilsners, lagers, pale ales): These degrade faster due to their lighter body and hop profile. Carbonation loss and oxidation will be more noticeable within 2–3 days.
• Heavy or Dark Beers (like stouts, porters, or barleywines): These beers tend to last longer in a growler due to their higher alcohol content and more robust flavor, which helps them withstand oxidation longer.
• Sours and High ABV Beers: Sour beers or high-alcohol brews age better than others.

(3) Pressurized or Non-Pressurized Growlers

• Pressurized Growlers: These growlers have a CO2 system (often a regulator and tap system) to maintain pressure and carbonation. This helps preserve the beer’s freshness  for a longer period.
• Non-Pressurized Growlers: These growlers rely solely on sealing and refrigeration to preserve beer. Without added pressure, the beer’s carbonation will be lost more quickly, particularly after opening.

(4)Opened or Unopened

• Unopened Growlers: When sealed and stored properly, unopened growlers can retain their carbonation and flavor for a longer time, typically one to two weeks, depending on the beer type and conditions.
• Opened Growlers: Once opened, beer begins to lose carbonation quickly. And the exposure to air accelerates oxidation. The beer will still be drinkable, but within a few hours to a day, it will become flat and stale.

Yes! While designed for beer, you can use a beer growler to store other beverages like iced coffee, tea, water, ice, or even cocktails. Just make sure to clean it thoroughly between uses to avoid flavor mixing.

Yes! KingStar provides a wide range of customization options such as materials, colors, engraving, logos, and artwork to make your growler unique. Additionally,  KingStar offers OEM / ODM service to suit every need. Customization is perfect for gifts, corporate branding, or personal use.

A VPR Cap (Vacuum Pressure Release Cap) for a beer growler is a specialized cap designed to maintain the freshness and carbonation of beer over an extended period. It can release excess pressure, and create a vacuum seal after pouring, ensuring the beer’s taste.

Beer growlers come in various sizes, typically ranging from 32oz to 128oz. The most common size is 64oz (1.9L), which is ideal for sharing. Choose the size based on how much beer you typically drink or how many people you intend to serve.
