Typically, you can store beer in a growler or crowler for about 2-3 days before it starts to lose its freshness and flavor. However, there are several factors that can affect how long your beer will stay good in a growler or crowler.
Factors Affecting Beer Freshness in Growlers and Crowlers
- Seal: The tightness of the seal on your growler or crowler will greatly impact how long your beer stays fresh. A good seal will keep oxygen out, which can cause the beer to go stale more quickly.
- Temperature: Storing your growler or crowler at the right temperature is crucial. Beer should be kept cold to help preserve its flavor and carbonation. Warm temperatures can speed up the oxidation process, leading to off-flavors.
- Light: Exposure to light, especially UV light, can cause beer to develop a “skunky” flavor. Keep your growler or crowler in a dark place to avoid this issue.
- Type of Beer: Some styles of beer, like IPAs, are more delicate and prone to oxidation than others. It’s important to consider the style of beer you’re storing when determining how long it will stay fresh.
Growler vs. Crowler: What’s the Difference?
Before we dive deeper into how long beer can be stored in growlers and crowlers, let’s first clarify the difference between the two:
- Growler: A growler is a resealable glass, ceramic, or stainless steel container used to transport draft beer. Growlers typically hold 64 ounces of beer and are meant to be consumed within a few days of being filled.
- Crowler: A crowler is a 32-ounce can that is filled and sealed on-site at a brewery or taproom. Crowlers are a more airtight option than growlers and are designed for longer storage periods.
How Long Can Beer Last in a Growler?
As mentioned earlier, beer stored in a growler is best consumed within 2-3 days to ensure optimal freshness. After that time, the beer may start to lose its carbonation and develop off-flavors. However, there are a few tips you can follow to extend the lifespan of beer in a growler:
- Keep the growler refrigerated at all times to slow down the oxidation process.
- Try to finish the beer within 24 hours of opening the growler to preserve carbonation.
- Choose a darker glass growler to protect the beer from light exposure.
- Make sure the growler is properly cleaned and sanitized before filling it with beer.
How Long Can Beer Last in a Crowler?
Crowlers are designed to have a longer shelf life compared to growlers due to their more airtight seal. Beer stored in a crowler can last anywhere from 1-2 weeks, depending on the factors mentioned earlier. To maximize the freshness of beer in a crowler, follow these tips:
- Store the crowler in the refrigerator to maintain its quality.
- Avoid exposing the crowler to direct sunlight or heat.
- Consume the beer within a week of opening the crowler for the best flavor.
- Keep the crowler upright to prevent any leaks or spills.
Signs that Beer Has Gone Bad
It’s important to be able to recognize when beer has gone bad to avoid consuming spoiled product. Here are some common signs that beer in a growler or crowler is past its prime:
- Flatness: If the beer has lost its carbonation and tastes flat, it’s a sign that it’s no longer fresh.
- Off-Flavors: If the beer has developed off-flavors like a cardboard taste or a sour aroma, it’s best to discard it.
- Cloudiness: Beer should be clear and bright. If you notice cloudiness or particles in the beer, it may be a sign of spoilage.
- Foul Smell: If the beer smells musty, rotten, or generally unpleasant, it’s a clear indicator that it’s gone bad.
Best Practices for Storing Beer in Growlers and Crowlers
To ensure that your beer stays fresh for as long as possible, consider the following best practices for storing beer in growlers and crowlers:
- Keep the container sealed tightly at all times to prevent oxygen from getting in.
- Store the beer in a cool, dark place away from direct light and heat sources.
- Consume the beer as soon as possible after opening the container to enjoy it at its best.
- Clean and sanitize the growler or crowler thoroughly before each use to prevent contamination.
