From the Manufacturer

Savor Your Beer

The way the brewer intended. With vacuum insulated 8/18 stainless steel, your beer stays deliciously cold all day. Our integrated VPR Cap technology provides a carbonation system to keep your beverage brewery fresh, and perfectly carbonated. The uKeg can also be used to force carbonate your own homebrew or other carbonated elixir.

Share With Friends

Besides quality, the best part about beer is toasting it. From your refrigerator or tailgate. The dispensing tap lets you easily serve your beer at home or at parties. This makes the uKeg a great way to share your own homebrew or local favorites.


18/8 Stainless Steel. Keeps beer cold all day.


VPR cap automatically maintains carbonation. From zero (off) up to 15 psi. One 8 gram CO2 cartridge lasts for one growler fill.


Easy to pour. Makes you the bartender.


GrowlerWerks is a company that defines the spirit of travel as we have invented the ultimate travel companion. The uKeg was designed with the core idea to savor your beer, sparkling wine, kombucha, cider, or any other carbonated beverage you enjoy, to the last drop and share it with friends wherever you escape to.

About the Startup

Describe your product in 3 words.

Craft. Innovation. Ease

How did you come up with the idea for this product?

A love of good beer, and a desire the make the experience better. We’re beer lovers living in a beer region. Who knows which came first, the love or the beer, but as engineers we recognized the need for a better solution. We decided to focus our skills and efforts on this endeavor.

What makes your product special?

After testing all the available options, we realized nobody had cracked the code on a pressurized growler that works. So we designed the uKeg: It’s easy to use, with an automatic regulator cap and integrated CO2, variable carbonation from zero (off) up to 15 psi, and a dispensing tap so you can easily pour beer without removing the cap. It also has a liquid sight glass, an ergonomic handle, and it’s easy to clean.

What has been the best part of your startup experience?

Ideas are fun and creative, and turning those ideas into high quality products is challenging. We've focused our deep engineering and design experience to produce a high quality product. It takes a lot of work and coordination to get it right, and we're proud when our beer-loving customers are happy.
