General Features of the uKeg 64

There are quite a few general features that come along with this beer growler.

Beer Tank

The tank that holds the beer is a double-walled, vacuum-insulated, and made from durable 18/8 stainless steel that will keep your beer cold all day when it’s not refrigerated. Once refrigerated your beer can stay fresh for up to a week or more.

When ordering, you can choose between three different colors and finishes: Black chrome, stainless steel, or copper. And if you don’t think the 64 ounce keg is beg enough, you can double the size and choose the large 128-ounce model.

Variable Pressure Regulation (VPR) Cap

Once you set the pressure, it will stay there. The great thing is, it will automatically regulate, so the pressure inside is optimized for the ambient temperature outside. Just choose your carbonation level, with a range of 0 – 15 psi.

Pressure Guage

The pressure gauge is located at the bottom of the keg, so it is easy to read. It’s circular design makes it one-glance worthy as it’s nice and clear.

Tap Handle

The tap handle can be changed, so you can add some personalization to the growler.  The handles can take silicone, rubber, metal, or wood.

Sight Glass

It shows how much of your tasty beer you have left inside. At a 64-ounce capacity, which is only 4 or 5 beers, make sure you keep an eye on this so you know when it’s time for a refill.


It uses a single food-grade CO2 cartridge to pressure and carbonation. The cartridges are in-expensive, but they will need replacing after 2 or 3 maximum capacity keg uses.

To replace it, just unscrew the cap and drop it in. It is very simple to replace, but it does mean that you will have to expose the beverage inside in order to replace it.


Because of the tight-fitting pressure cap, it will keeps your beer fresh for 1 to 2 weeks if kept in the refrigerator.

Dispenser Tap

The tap can pour your drink without needing to remove the cap, and the taplock prevents unwanted dispensing.

Oh, one more thing. Remember to have this lock on, when you have changed the CO2 cartridge so it doesn’t pressurize your beer while you’re just screwing on the lid mid-batch.

How to Clean the uKeg

Like most new products, you want to make sure it is clean before use.  You will also should clean the growler every time you empty it.

This product IS NOT dishwasher safe and can get ruined if you try to clean it using the dishwasher.  Dish soap is also not recommend for cleaning.

It is best to fill the keg with warm water and a cleaning tablet, then shake well and rinse.  Even better, if you have any CO2 left, you can quickly pressurize the cleaning solution and run it through the tap.

If you don’t have any cleaning tablets, you can substitute baking soda.

Odds and Ends

  • Do not use for a beer fermenter
  • Hand wash only
  • Store upright
  • No hot liquids over 120°F
  • Keep it clean
  • Using a fill-tube is recommended
  • Let the beer settle before using to avoid excessive foam

Although the uKeg 64 is a bit more expensive than other growlers on the market, it is worth the money if you are wanting a good-looking quality product. It is well constructed, easy to use, and the build quality just leaps out at you over most of its rivals.
