Can You Put a Keg in the Garage?

Remember back in college when you’d buy a keg for the party that weekend? My partying days may be long gone, but I still prefer daft beer to bottles. Even if you don’t have a Kegerator, you may be wondering if you can put a keg in your garage.

You can put a keg in the garage if you store it in an insulated fridge. Kegs can’t get too warm on the inside or they’ll cause mold and mildew to grow. By insulating the garage, adding maintaining the temperature, and keeping it out of direct light, your keg can store drinks without causing problems.

In this article, you’ll learn how you can store your keg in your garage, as well as different ways to keep it cooler longer. I’ll also offer a few suggestions on how to increase the lifespan of your keg.

How to Store a Keg in the Garage

Kegs are extremely popular, but it’s not the easiest thing to find a place to store one.

When my friends back up in Pittsburgh would throw a party, they stored the keg in the garage because that’s where everything was. They had beer pong, sofas, a big TV and even a pool table there. It made sense to keep the keg there too.

We’re going to assume that you store your keg in a kegerator or mini-fridge – trust me, it’s an absolute must! The next few sections will detail how you can get the most out of your keg when it’s in your garage.

Here’s how you can store your keg in the garage:

  1. Insulate the walls of your garage. Without insulation, your keg will quickly start to warm up to the air around it. Insulating the walls of your garage can help to keep your entire garage cooler, which in turn helps keep your keg cooler.
  2. Avoid direct light. Don’t leave your keg near windows where direct sunlight can it. Similarly, you shouldn’t put it right under your garage lights, even if they’re LED bulbs that don’t put off much heat.
  3. Keep the pressure even. Your keg should have an interior pressure that rests between 10 to 12 PSI. If it gets too high, it’ll pour out too quickly, causing it to go flat quickly. On the other hand, low pressure can cause excessive amounts of foam to build up inside the liquid.
  4. Never jam-pack your kegerator. Refrigerators need airflow to be able to cool properly. When you over-stuff the fridge and there’s no room inside of the keg, your kegerator has to work harder to keep everything cool. This uses more energy and takes longer to cool down.
  5. If your mini-fridge has room for multiple kegs, always use the older one first. For example, if you put one bottle in on Monday and another in on Tuesday, drink the bottle from Monday before you pull out the Tuesday bottle. This rotation will preserve your drinks much longer.

Insulating Your Keg

The most important step you can take is to maintaining the temperature around your keg. Without insulation, you’ll be fighting an uphill battle.

Remember that your keg needs to be inside of a fridge of some sort to maintain its inner temperature. Let’s review how you can insulate your keg and its surroundings with a few helpful suggestions.

Foam pipe insulation is one of the best tools to keep the pipes of your keg staying low. Pipes can overheat quickly due to the increased ambient temperature in a garage. When temperatures are soaring during the summer season, you should keep the pipes coated with M-D Building Products Self-Sealing Tube Pipe Insulation.

Remember that frozen pipes can be just as bad. Even if your garage doesn’t get too hot, the pipes can freeze, ruining the purpose and function of the keg. Other than pipe insulation, you can also try using spray foam to regular the interior temperature.

Another suggestion to insulate your keg is to insulate the whole garage. If your garage isn’t already insulated, you can use spray, foam batts, or panels to keep it maintained inside. Also, try to block exterior light sources from penetrating the windows of your garage. You can block them with DIY window panels.

Beginner keg owners often make the mistake of thinking that they can leave a keg without working on it. Much like a car, kegs need attention and maintenance regularly. If you can find out how to insulate and run your keg as you should, then you can store it in a garage, shed, or any other sheltered structure.

Any liquid that goes into the keg needs to be put in at a low temperature. This placement will prevent your keg from working harder than it should since it doesn’t have to lower the warmth of a new hot liquid.

A final tip: Always allow your keg to run properly. It shouldn’t turn off when it’s hot in the garage. Expect it to run for several hours each day if the interior temperature of your garage is above 100 degrees Fahrenheit (38 C).

How Long Can You Leave a Keg in the Garage?

Leaving drinks in your keg is just as important as using it in the first place. If you can’t store anything for extended periods of time, what’s the point in using a keg?

If your garage is well-insulated, then you can leave your keg in there for quite some time. Weeks or months are very possible since there’s nothing warming up your keg. As long as it stays inside of the cooling container, your keg will be ready to pour fresh, ice-cold drinks.

Higher ABV, or alcohol by volume, results in a better storage method. When your drinks have more alcohol, they don’t go rotten nearly as quickly. Furthermore, less alcohol content causes your drinks to freeze eventually. If you don’t want your beverages to get frozen, then you’ll need to get drinks with at least 7% ABV.

You should also focus on the type of alcohol that goes into your keg. Some beers last longer than others. For example, beers with more hops won’t stay fresh as long as beers with lower amounts of hops.

However, malted beers tend to get better with age, much like wine. If you want to get a delicious beverage whenever you need it right from your garage, then malted drinks are the way to go. Note that you can store any type of drink in the keg in your garage, but the results will vary.


Kegs are undeniably convenient. If you want to keep it cold in the garage, then you’ll need to store it in a fridge of some sort. Insulation, removing it from direct light, and rotating the drinks will make it last the longest.

Here’s a quick recap of the post:

  • Use pipe insulators on the fridge to keep your keg cold inside.
  • Malted beverages typically get fresh over time.
  • Hoppier drinks start to lose their freshness over the following weeks.
  • Higher ABV is much better for long-term beverage storage.
  • Keep your keg pressured between 10 to 12 PSI.
