Beer's Lifespan: How Long Does Beer Last In A Fridge?

How long a keg of beer lasts depends on a number of factors, including the type of beer, the way it is stored, and the method used to dispense it. Pasteurised beer typically has a shelf life of 90-120 days, while unpasteurised beer will last 45-60 days. However, these times refer to beer stored at the correct temperature and pressure, and the method of dispensing can also have a big impact on how long a tapped keg will last. Using a party pump or similar will introduce oxygen into the keg, causing the beer to go flat and spoil within 12-24 hours. Using a kegerator or draft system with CO2, on the other hand, will not impact the beer's freshness as long as the correct temperature and pressure are maintained.

The beer will last 45-60 days if it is non-pasteurised

The shelf life of beer in a keg depends on a variety of factors, including the type of beer, the method of dispensing, and the storage temperature.

Non-pasteurised beer has a shorter shelf life than pasteurised beer. When stored at the proper temperature and dispensed with CO2, non-pasteurised beer will last for about 45 to 60 days. This is because non-pasteurised beer is more susceptible to spoilage due to oxygen and bacteria.

To ensure the longest shelf life for non-pasteurised beer in a keg, it is important to maintain the proper temperature and pressure. The recommended storage temperature for most beers is 38 degrees Fahrenheit (3-4 degrees Celsius). Storing the keg at room temperature can cause bacteria to form, while temperatures below 28 degrees Fahrenheit can cause the beer to freeze.

Additionally, the method of dispensing can affect the shelf life. Using a party pump or keg tap introduces oxygen into the keg, which causes the beer to go flat and spoil within 12 to 24 hours. On the other hand, dispensing with CO2 helps to maintain carbonation and slows down the spoilage process.

It is worth noting that the freshness of beer also depends on the type of beer and personal taste preferences. Some beers, such as IPAs, have a shorter optimal freshness window, while others, like malt beers, may last longer. Regular cleaning of the kegerator lines is also crucial to maintaining the freshness of the beer.

The beer will last 90-120 days if it is pasteurised

The longevity of beer in a keg depends on a variety of factors, including the type of beer, the method of dispensing, and the storage temperature. However, if the beer in the keg is pasteurised, it will typically last 90-120 days, or approximately 3-4 months, under optimal conditions.

Pasteurisation is a heat treatment that kills bacteria and extends the shelf life of beer. Most imported and domestic beers are pasteurised, and this process significantly increases the longevity of the beverage. The countdown for the shelf life of pasteurised beer starts from the day the keg is filled at the brewery, not when it is tapped or purchased. Therefore, it is important to check the "'born-on' date or expiration date on the label of the keg to ensure optimal freshness.

Additionally, the method of dispensing plays a crucial role in the longevity of the beer. Using a kegerator or draft system with CO2 to dispense the beer will not impact its freshness, as long as the keg is stored at the proper temperature and pressure. However, if a party pump or keg tap is used, oxygen is introduced into the keg, causing the beer to go flat and spoil within 12-24 hours.

To ensure the best quality and longevity of your pasteurised beer, it is recommended to store the keg at a temperature of around 38 degrees Fahrenheit (3-4 degrees Celsius). Maintaining this temperature range will not only preserve the freshness of the beer but also facilitate a smooth pouring experience. Allowing the temperature to rise above 50 degrees Fahrenheit can lead to bacterial growth, while decreasing the temperature below 28 degrees Fahrenheit may cause the beer to freeze, compromising its taste.

In summary, pasteurised beer in a keg can be expected to last 90-120 days when stored and dispensed under optimal conditions. However, it is always important to refer to the manufacturer's guidelines and recommendations for the specific type of beer and dispensing system.

The beer will last 12-24 hours if a party pump is used

If you're planning on using a party pump to dispense beer from a keg, you'll need to finish it within 12-24 hours. This is because party pumps introduce oxygen into the keg, which causes the beer to go flat and spoil quickly. Oxygen is the enemy of beer!

If you're using a kegerator or a draft system that uses CO2, your beer will stay fresh for much longer. Non-pasteurised draft beer will last around 45-60 days, while pasteurised draft beer will last around 90-120 days. These estimates assume that the keg is stored at the proper temperature and pressure.

It's important to note that the countdown for kegged beer starts from the day the keg is filled at the brewery, not when you tap it or buy it. So, if you're planning on buying a keg, check the label for a "born on" date or expiration date. If the beer has passed its expiration date, it's best not to drink it.

To ensure your beer stays fresh, keep your kegerator lines clean. It's recommended to clean them every time you change a keg or once every 2-3 months, depending on how much beer you dispense.

The beer will last longest when stored at 38 degrees Fahrenheit

If you want to keep your beer as fresh as possible for as long as possible, it's also important to keep it away from light and to ensure that the keg is stored at the proper pressure. Additionally, the countdown to a keg's expiration starts from the day it is filled at the brewery, not the day it is tapped or purchased.

The type of beer will also affect how long it lasts. Mass-produced beers often have a shelf life of 120-180 days, whereas craft beers vary and unpasteurized beers tend to have a shorter shelf life of around 45-60 days.

The beer will be ruined if stored at room temperature for more than 5-10 minutes

The beer in your keg will be ruined if stored at room temperature for more than 5-10 minutes. This is because bacteria will start to form inside the keg, which will eventually ruin your beer and even make it unsafe to drink.

To prevent this from happening, it is recommended that kegs are stored at a temperature of 38 degrees Fahrenheit (3-4 degrees Celsius). This is the optimal temperature for freshness and pouring. If the temperature is too warm, the beer will also pour foamy.

It is also important to note that the countdown for freshness starts from the day the keg is filled at the brewery, not when it is tapped or purchased. The fresher the keg, the better the beer will taste. For non-pasteurised draft beer, the keg will remain fresh for about 45-60 days, and for pasteurised draft beer, it will last about 90-120 days.

Additionally, the method of dispensing the beer will also impact its freshness. Using a kegerator or draft system with CO2 will not affect the beer's freshness, as long as the keg is stored at the proper temperature and pressure. However, if a picnic pump, party pump, or keg tap is used, oxygen will be introduced into the keg, causing the beer to go flat and spoil within 12-24 hours.

To ensure the best quality and taste of your beer, it is crucial to follow the recommended storage temperature and dispensing methods, as well as to consume the beer within the recommended freshness timeframe.
