What is a growler?
A growler is a container used for storing and transporting beer. It is typically made of glass, ceramic, or stainless steel and has a capacity of 32 or 64 ounces. The name “growler” is said to have originated from the sound the beer makes when it is being transported, which sounds like a growling stomach.
Growlers have gained popularity in recent years as a way to bring fresh, local, and specialty beers from breweries and taprooms to home or other locations where the beer is not otherwise available. They are also a great way for beer lovers to try a variety of different beers without committing to a full six-pack or keg.
What types of beverages can be stored in a growler?
One of the great things about a growler is the versatility it offers to store a variety of beverages. From beer to cold brew coffee, a well-designed growler is the perfect container to keep your favorite drinks fresh. Here are some of the beverages that can be stored in a growler:
- Beer: The most common beverage stored in a growler is beer. This is because beer is often sold in breweries and taprooms by the glass or in growlers to take home. A well-crafted growler will keep your beer fresh and carbonated for days after it has been poured.
- Cold Brew Coffee: Another popular drink that can be stored in a growler is cold brew coffee. The airtight seal of the growler keeps the coffee fresher for longer and the insulated walls help prevent temperature fluctuations.
- Kombucha: Kombucha is a fermented tea that can be stored and brewed in a growler. The airtight seal of the growler helps to keep out bacteria and the large capacity allows for larger batches to be brewed and stored.
- Cider: Like beer, cider can also be stored in a growler. Once poured, the airtight seal will keep the cider carbonated and cold for several days.
- Soda: Homemade soda can also be stored in a growler. The airtight seal of the growler will keep the carbonation intact, making your soda taste fresh and fizzy.
As you can see, a growler is a versatile container that can be used to store a variety of beverages. The airtight seal is perfect for keeping drinks fresh and carbonated for longer, and the insulated walls help maintain temperature. With such a wide range of beverages that can be stored, it’s easy to see why growlers have become a popular choice for both brewers and drinkers alike.
How is a growler designed to preserve the freshness of the beverage?
Growlers were primarily designed to maintain the taste and quality of the freshly brewed beer, cider, or any carbonated beverage right from the draft until you consume it later. Here are some ways how a growler can preserve the freshness of the beverage:
- Materials: Most growlers are made of glass, ceramic, or stainless steel. These materials are preferred because they do not react with the beer and allow zero air and UV light to penetrate the glass, thus preserving the beer’s flavor and freshness. Glass is also easy to clean, whereas stainless steel is durable and doesn’t break easily.
- Sealing: A growler should be tightly sealed to prevent the beer from oxidizing. Incorrectly sealed growlers can lead to flat beer and negatively impact its flavor. Most growlers use airtight lids or caps that help to keep the beer’s carbonation levels. Also, some growlers come with flip-top caps that create an additional seal to make sure no air seeps in.
- Temperature management: Temperature changes can have a significant impact on beer’s freshness and quality. A growler should be kept at a cool temperature before consumption. Some growlers come with insulating features that can keep the beer cool for extended periods. Maintaining temperature control can have a significant impact on flavor, aroma, and carbonation.
Below is a table explaining the pros and cons of different growler materials:
|Easy to clean, maintains freshness of the beer, does not alter the taste or smell of the beer
|Fragile and heavy to carry around
|Retains the beer’s temperature, keeps beer fresh and maintains its flavor and aroma
|Fragile and not ideal for travel
|Durable, shatterproof, and lightweight. Can keep the beer carbonated and chilled
|Can alter the taste of the beer slightly, and challenging to clean the inside if not scoped or angled in the right way.
Understanding the ways a growler preserves freshness through its material, sealing, and temperature management can be instrumental when researching or purchasing the right growler for your beverage needs. It also gives us insight into making and preserving beer, although you don’t always have to be an expert to enjoy a quality beer!
What factors affect the shelf life of an unopened growler?
As much as you’d love for the beer in your growler to last forever, that’s just not possible. The lifespan of an unopened growler is affected by a number of factors. Knowing what affects the shelf life of your beer can help you determine how long it will last and when it’s time to drink it.
- The type of beer: Different types of beer have different shelf lives. For example, a hoppy IPA will have a shorter shelf life compared to a malty stout. This is because hops degrade very quickly and can affect the taste of the beer.
- The alcohol content: Beers with a higher alcohol content tend to have a longer shelf life. This is because alcohol acts as a preservative and can help prevent spoilage.
- The filling process: How your growler was filled can also affect its shelf life. If your growler was filled using a counter-pressure system, it will likely have a longer shelf life compared to a growler that was filled using a tap or a hose.
Another factor that affects the shelf life of an unopened growler is light. Exposure to light, especially UV light, can cause the beer to become “light-struck”. This will affect the flavor and aroma of the beer, giving it a “skunky” taste.
If you’re curious about how long your beer will last, the table below can serve as a general guideline:
|Shelf Life of Unopened Growler
|Belgian strong ale
It’s important to remember that these are just guidelines and your beer may last longer or shorter depending on the factors mentioned above. If you want to extend the shelf life of your beer, store it in a cool, dark place and keep it away from light and heat.
How to Properly Store an Unopened Growler?
Growlers are a popular choice among beer enthusiasts as they offer a convenient way to transport fresh and unique craft beer flavors. However, improper storage can result in a compromised taste and aroma of the beer, even when the growler is unopened. This is why it’s crucial to know how to properly store an unopened growler to ensure its quality and freshness.
- Keep it refrigerated: If you plan to store an unopened growler for longer than a day, it’s best to keep it in the fridge. The ideal temperature range is between 35-45°F to maintain the freshness of the beer.
- Store it upright: Always store a growler in an upright position. Storing it on its side can cause the beer to leak and oxidize, compromising the flavor and aroma of the beer.
- Protect it from sunlight: Direct sunlight can cause the beer to spoil, so make sure to store your growler in a cool and dark place. UV rays can trigger the breakdown of hops, resulting in a skunky beer flavor.
To have a better understanding of how long an unopened growler can last, here is a table that shows a rough estimate of the shelf life of an unopened growler:
Note that the shelf life can vary depending on factors like storage conditions, brewery fill procedures, and carbonation levels.
To sum it up, storing an unopened growler requires some attention to detail, but it can be effortless with these simple tips. Keep it refrigerated, store it upright, and protect it from sunlight to ensure its freshness and quality.
How to Determine If an Unopened Growler has Gone Bad?
Growlers are containers used to transport and store beer, usually glass, but now also metal and plastic containers. They are highly favored by craft beer enthusiasts because they allow them to take their favorite beers home directly from the source. Unopened growlers can last for a while, but they’re not immune to spoilage. Below are some of the signs that an unopened growler has gone bad:
- Foul Smell: A bad or sour smell is an indication that a growler has gone bad. Beer should smell fresh and inviting. If it smells bad, you should probably toss it.
- Mold or Sedimentation: If there’s sedimentation or mold inside the growler or around its seal, it’s a sign that bacteria have set in. This can render the beer undrinkable.
- Flat or Fizzy: Fresh beer should have a little fizz to it, but it should not be flat. If the beer is flat or unusually fizzy, it may well have gone bad. You can test it by pouring it into a glass and looking for bubbles.
If you want to be double sure that your unopened growler hasn’t been corrupted, there are a couple of additional steps you can take:
Check The Date: Many breweries now print the date that the beer was put into the growler on the container. Once you buy a growler of beer, write down the date on which it was filled. Be sure to drink your beer within the recommended timeframe usually displayed on the label or in the brewery’s website.
Store in the Right Place: Proper storage is key to lengthening the life of your growler. Keep it sealed and store it in a cool, dark place. Don’t store your growler in direct sunlight, or it may go bad sooner than you expect.
|How Long It Lasts
|In the fridge at a temperature of 38-40°F
|Outside the fridge at room temperature
By following these tips, you can ensure your growler stays fresh and enjoyable for longer. Just remember to drink it before it goes bad!
Can an unopened growler be kept in the freezer?
Yes, it is possible to keep an unopened growler in the freezer, but it is not recommended. Growlers are typically made of glass, which can be fragile and easily break or shatter when placed in extreme temperatures. Additionally, the beer inside the growler will expand as it freezes, possibly causing the glass to break or the cap to pop off.
- It is best to keep growlers in a cool and dark place, such as a refrigerator or a cellar, where the temperature is consistent and not too high or low.
- If you must freeze an unopened growler, make sure it is completely sealed and try to lay it on its side to minimize the risk of breakage. Also, leave some room for the beer to expand as it freezes.
- When you are ready to drink the beer, let the growler thaw completely in the refrigerator before opening it. Do not try to speed up the thawing process by putting it in warm water or the microwave, as this can cause the beer to go flat or lose its flavor.
If you do decide to freeze a growler, keep in mind that the beer will not last as long once it is thawed. Freezing and thawing can affect the taste and quality of the beer, so it is best to consume it within a few days of thawing.
Overall, it is best to plan ahead and only purchase or fill a growler when you know you will consume it within a reasonable amount of time. This will ensure that the beer tastes fresh and enjoyable, without risking any damage to the growler or affecting the quality of the beer.
How to clean and maintain a growler?
Proper cleaning and maintenance of your growler is important to ensure that it maintains its quality and taste, as well as to prolong its lifespan. Here are some tips on how to clean and maintain a growler:
- After each use, rinse your growler with hot water to remove any remaining beer residue and allow it to air dry before storing it.
- Do not use soap, as it can leave a residue that affects the taste of the beer.
- To deep clean your growler, use a mix of water and white vinegar or baking soda. Rinse thoroughly with hot water and allow to air dry.
When storing your growler, make sure to keep it in a cool, dry place, away from direct sunlight and heat sources, as this can affect the quality of the beer inside. Avoid storing your growler with the cap on, as this can trap moisture and lead to mold growth.
Additionally, it is important to check your growler for any cracks or damage before use, as this can affect the carbonation and result in a flat beer. If you notice any cracks or damage, it is best to replace your growler instead of risking a ruined batch of beer.

Are there any health risks associated with drinking from an old growler?
When it comes to drinking from an old growler, there are some concerns regarding potential health risks. Here are some important things to keep in mind:
- Bacterial Growth: If a growler is not properly cleaned and sanitized, it can become a breeding ground for bacteria. This is more likely to happen if a growler has been filled with beer that is not pasteurized or contains live yeast cultures. Over time, these bacteria can multiply and could potentially cause illness if ingested.
- Mold: If a growler is not properly dried after washing, it can develop mold. Mold can produce harmful toxins that could make you sick. If you notice any mold growing in your growler, it’s best to discard it.
- Oxidation: Over time, beer can become flat and oxidized. This can change the taste of the beer and make it less enjoyable to drink. While drinking oxidized beer is not necessarily harmful to your health, it can impact your overall experience.
It’s important to note that these health risks are not exclusive to growlers – they can occur with other containers that hold beer or other types of liquids. The key is to properly clean and maintain your growler to ensure it is safe to use.
If you suspect that your growler has been compromised in any way, it is best to err on the side of caution and discard it. It’s also important to follow any guidelines provided by the brewery or establishment where you filled your growler, as they may have their own rules and recommendations for how long a growler can safely be stored before being consumed.
Bottom line – drinking from an old growler does pose some health risks, so it’s important to be mindful of how you handle and care for your container. By doing so, you can avoid any potential health concerns and enjoy your beer to the fullest.
What to do with an unopened growler past its shelf life?
When it comes to growlers, it is important to remember that they do have a shelf life, just like any other food or beverage. While beer can last for months or even years, the same goes for growlers that are unopened and properly stored. However, if a growler has been sitting for too long, it may no longer be safe or enjoyable to drink. Here are some options for what to do with an unopened growler that has passed its shelf life:
- Return it to the brewery: Many breweries will allow you to return an unopened growler that has passed its shelf life. They may offer a refund or a replacement for a fresh fill.
- Reuse the container: You can always reuse the container for other purposes, such as storing dry goods or making homemade gifts.
- Dispose of it properly: If you cannot return or reuse the growler, be sure to dispose of it properly.
