For pasteurized draft beer about days. Secondly, how long does it take Draught beer served using compressed air or a party pump to go bad? A typical keg pump uses air or oxygen, which is hand pumped into the keg to draw beer to the faucet. Hand pumps are only recommended for single day events because oxygen doesn't preserve the beer like CO2 and will cause the beer to go flat and spoil within hours.
When you buy a keg it should only have CO2 in it. As such the keg does not go flat. If you tap it with a true system using CO2 as the gas then you should be able to tap and re- tap the keg as you wish, since you are not introducing a foreign gas.
This is because the keg remains pressurized, but avoids oxidation. In this instance, your beer can remain fresh for months, but the overall time really depends on the beer itself. If your beer is pasteurized, then it will likely last for at least three months, maybe even six if you store it at the correct temperatures.
If you dispense your beer with a party pump , which uses air instead of CO2 to drive the beer, you can only expect your beer to remain fresh for hours. If you keep your kegs warm, and drive them with CO2 through a jockey box or other faucet, they will most likely last a couple of months. Should I untap a keg to keep it fresh? In the sense that you are asking, no it won't do anything to spoil the beer. Just do exactly as you say and unhook the keg, leaving the keg pressurized.
How many kegs can you get out of a 5 lb co2 tank? If you are using the CO2 only to dispense the beer, not to carbonate it, you may get as many as thirty 5 gallon Cornelius kegs out of one 5 lb. CO2 cylinder. However, most homebrewers are also using CO2 to force carbonate their brew, so this brings it down to around ten 5 gallon Cornelius kegs out of one 5 lb.
Do untapped kegs need to be refrigerated? This means that your beer will interact with the oxygen, which may, in turn, affect the way your beer tastes.
In most cases, a keg that uses a manual pump will provide fresh beer for only a few days before the beer becomes noticeably stale, so make sure to enjoy it fast. Setting up a CO2 dispenser is the way most beer fanatics opt for. When beer is oxidized, the taste is changed and it becomes stale. The carbon dioxide does little to affect the state of the drink, so you can continue to use the dispenser and have beer that tastes the same from start to finish.
That being said, with CO2 dispensers, your beer can last you for over 3 months. In some cases, depending on the conditions, it can last for almost 6 months. Most edible products go through a certain chemical process as they age. That being said, the temperature that things are stored has a big influence on how long or how short the life of the product will be. The same is true with beer.
Although the alcohol in the beer does help to slow down the overall process, the temperature will affect the life span of your beer and determine how long it will be before your beer turns stale. Like other products, the fermentation of your beer speeds up when exposed to higher temperatures.
Since the average room is around 65 to 70 degrees, your beer will definitely be affected by the temperature. This is fine if you only have a small keg, or if you plan on downing your beer in a few days, but not if you want it to last long term. On average, a keg of beer will retain its flavor for only a couple weeks before its taste begins to wane.
The best way to retain your flavor is to store it at a cooler temperature. And we do mean cool , not cold. Another thing that can help determine the length of time you have with your keg is whether the beer is pasteurized or non-pasteurized. For the most part, pasteurized products are bound to last longer. This is because of the processes companies use to keep the product fresh. Beer naturally has a lot of yeast in it due to its formulation process.
With pasteurization, a lot of that yeast is killed off, enabling the beer to last much longer in comparison to non-pasteurized beer. A keg of non-pasteurized beer, even when placed in good conditions, will last just a few months maximum. The recommended temperature for storing draft beer is 38 degrees according to the Draught Beer Quality Manual. This is the optimal temp for freshness and pouring. In addition to affecting the freshness of your beer, warm beer also has the tendency to pour foamy.
Always make sure your keg is properly chilled when pouring. You cannot store a keg of beer at room temperature. Bacteria can form in beer if it's temperature rises above 50 degrees.
Since it is a liquid, keeping beer at too cold of temperature is also a no-no. Beer will freeze at around 28 degrees depending on its alcohol content.
We hope this information will help you when deciding to purchase your next keg of beer. One other thing to consider is choosing the right size keg.
