Everything You Need to Know About the GrowlerWerks uKeg

May 10, 2017

Walking into your favorite craft brewery or growler bar with the GrowlerWerks uKeg will catch the eyes of craft beer amateurs and veterans alike. I had always admired these hefty beauties but they’re a big investment, even for the most serious of craft beer drinkers. So when GrowlerWerks asked if I could do a honest review of their pressurized growler, I couldn’t say no!

After spending almost two weeks with the uKeg growler, my life has been changed. Now I can never go back to a regular growler.

Overall Thoughts Using the uKeg Pressurized Growler

I must admit, since moving to Texas my growler game has seriously diminished. That’s probably due to TABC and their backwards laws that restrict many breweries from selling their beer on-site, to-go. There are a few spots around town, plus some solid brewpubs, that offer growler fills of special or seasonal brews.

What I’ve found to be great about the uKeg specifically, is how I can keep those seasonal brews or beers from the microbreweries, fresh and in my fridge. This growler lets you enjoy those beers just like you would if you ordered at the brewery or got it straight from the tap.

There is a bit of a ‘learning curve’ when switching from the ways of a standard growler to a pressurized growler like the uKeg. That’s why I’ve included easy step-by-step instructions to using and cleaning the growler, as well as tips to getting the best, freshest pour every time.



Beautiful, Eye-Catching, and Functional

growlerwerks ukeg 64 reviewGrowlerWerks has created a sleek, heavy-duty growler that is for serious beer drinkers. The uKeg is an investment but it means enjoying fresh craft beer in reasonable quantities without letting oxygen ruin the beer.

There are two size options for the uKeg : 64-ounce and 128-ounce. Both sizes are available either copper-plated or the standard silver. I received the standard 64-ounce uKeg in exchange for this honest review.

After placing one of the two included CO2 cartridges (each one lasts a growler fill) into the cap, you fill the growler with beer, screw on the cap, and adjust the dial the appropriate pressure.

A pressure gauge on the front of the growler tells you how many pounds per square inch (PSI) of pressure are inside the growler so that you can adjust the dial accordingly.

I stretched one growler fill across a full week and found that the first pint was just as fresh and carbonated as the first.

If you’re worried about the expense of buying CO2 cartridges, no worries! You can find them cheap on Amazon. Get a pack of 10 for less than $20. Link here.

GrowlerWerks uKeg Instructions

The uKeg might seem complicated, but once you figure out how to adjust and work the pressure, it’s quite easy! Don’t get thrown off by all the steps, I had this process down by my second growler fill.

  1. Make sure the silver dial is in the off position, then install the CO2 cartridge into the sleeve.
  2. Tighten the sleeve fast and hard- you’ll hear air escaping if you don’t twist fast enough!
  3. Clean your uKeg growler before your first fill.
  4. Head to your favorite brewery or growler bar and ask for a fill of your desired brew.
  5. Cap your uKeg and turn the pressure on slightly.
  6. Then, just pour and enjoy!

uKeg Carbonation Guide

GrowlerWerks knows no one likes flat beer, but too much foam in the wrong beer isn’t fun either. That’s why they’ve provided the chart below to help you choose the right carbonation for your brew.

This is what your beer will look like if you have your uKeg growler set to the wrong PSi.

I found that this is the tricky part, but really, there’s no way you can screw things up too badly.

If you see the beer is coming out too foamy, turn down the pressure, and vice versa.

And keep in mind, this is just a guide, you can always experiment to suit your own taste!

Beer Type PSI
Stouts, Porters, Cream Ales, Barley Wines 3-6 PSI
Brown Ales, Ambers, Red Ales 5-8 PSI
IPAs, Pale Ales, Wheat Beers, Other Ales 7-10 PSI
Lagers, Pilsners, Ciders, Kombuchas 9-12 PSI
Wine 12-15 PSI

uKeg Growler Maintenance and Care

Before your first fill, or for deeper cleans every few fills, follow the below steps. For general cleanings, gently wash with soap and water.

  1. Remove cap and fill uKeg with hot water. Dump out and repeat twice more.
  2. Rinse cap and cartridge sleeve with hot water.
  3. Shake with tap open facing downward.
  4. Fill with hot water and 1 tablespoon of bake soda.
  5. Shake well and let sit for ten minutes.
  6. Empty bottle and rinse all parts. Move tap handle several times during the rinse.
  7. Allow to dry with cap off and tap open.

    I hadn’t heard of this growler before. Very cool! This is perfect for the ultimate beer nerd!

    I just received one for my birthday. First couple of pours – WAY too foamy. I had PSI dial set at 10 PSI (red lager). Can I ask what you generally have the dial set at?

    Thank you for this article. I’m still researching which pressurized growler to purchase .

    I have one! Got it as a b-day gift from my bro. I just finished my first full growler and am pretty happy with how fresh the last beer tasted, 1 week after getting it filled. I’m stoked that I can get growlers fills and not rush to drink it before it goes flat. I came to your site for cleaning instructions since I don’t have the tablets. Thanks for posting those.
