How Long Does Beer Last In A Keg

If you’ve ever gone to a party or bar and noticed the presence of a big metal keg, chances are there was some beer inside. But how long can you keep that keg full of beer around before it starts going bad? Knowing when to change out your beers in the keg is not always an exact science, but understanding the limited shelf life of a batch of brew can help ensure optimal freshness for your next event. In this blog post, we’ll explore the basics surrounding how long does beer last in a keg and get into the principles behind keeping your beer fresh.

The History Of Kegs Beer

Kegs beer has been around for centuries. Its origin is often disputed, but most historians point to the brewing practices of ancient Germanic tribes as the first use of what we now recognize as modern kegged beer. Throughout the Middle Ages and Renaissance, brewers used wooden barrels or caskets to store their suds, though the technology surrounding them has improved significantly since then.

In the 19th century, kegs made of metal began to become popular in Europe and eventually across the globe. Kegs allowed brewers to store large volumes of beer for longer periods of time, as well as reduce waste from broken bottles. This technological advancement revolutionized the beer industry and gave rise to the prevalence of draft beer in bars and pubs.



How Long Does Beer Remain Fresh?

Beer can remain fresh for quite some time if it is stored correctly. For unopened cans or bottles, beer will usually last at least six months beyond the printed expiration date with proper storage conditions such as cool temperatures and away from direct sunlight. However, once opened, beer should be consumed within two to three days for optimal flavor before the quality begins to decline. If you store opened beer in the refrigerator, it can last up to three weeks before it starts to lose its flavor and aroma.

Why Storage Temperature Matters With Beer?

It is important to store beer at the right temperature, as this can affect how long it remains drinkable. In general, beers should be kept cool at 45-55 degrees Fahrenheit, but some styles may benefit from lower temperatures of around 35-40 degrees. Storing beer too warm will cause the flavors and aromas to change over time in an undesirable way. Additionally, storing beer at warm temperatures can cause the carbonation to dissipate faster and make your beverage go flat sooner.

• Proper storage temperature is required to maximize shelf life.

Non-Pasteurized Beer

Non-pasteurized beer has a shorter shelf life than pasteurized beer, and should be consumed within 30-60 days after being tapped. This is because the yeast will continue to eat up the sugars in the beer and produce excess carbon dioxide, making it go flat faster.

Pasteurized Beer: Pasteurized beer can last up to six months in a keg. This is because the pasteurization process kills off any yeast or bacteria that could potentially cause the beer to go bad. However, it is important to note that this shelf life can be affected by how it is stored and how often it is used.

Factors That Affect Its Freshness Of Beer In A Keg

1. Temperature: The temperature at which beer is stored can significantly affect its freshness and taste. Warm temperatures accelerate the rate of oxidation, allowing oxygen to enter the keg and mix with the beer inside, resulting in a stale or “off” flavor. Optimal storage temperatures are around 45-55°F (7-13°C).
2. Age: As beer ages, it begins to lose its flavor and aroma. Keeping a keg as fresh as possible means using it quickly, within 2-3 months of purchase. Keep track of the purchase date so you don’t accidentally over age your beer!
3. Carbonation: Too much or too little carbonation can negatively affect the taste and texture of your beer. Make sure to check the pressure every few weeks, and adjust as needed to get it back up to optimal levels.
4. Oxygen: Oxygen exposure is one of the biggest enemies of freshness when it comes to beer in a keg. It can cause the beer to oxidize and taste stale, so make sure all connections are sealed tight at all times.
5. Cleanliness: Keeping your keg clean is essential to maintaining its freshness. Anytime you tap a new keg, sanitize all of your equipment before use to avoid any off-flavors from contaminating the beer.

These are just a few of the factors that can affect the freshness of your beer in a keg. With proper care, you can keep your brews tasting great for longer!
