I received this growler as a present, and i've taken it to get filled a couple of times and everyone is pretty impressed by it. It pours like a bar tap, I was very surprised of how well it works. Good job!

I really enjoy the ability to take a newly discovered craft beer from a taproom home. And enjoy it without noticeable degradation even weeks later.



If you're like us, many of your favorite microbrews aren't sold in bottles. GrowlerWerks was created by local Portlanders who love craft beer. We've drawn on a combined 47 years of engineering and product-design experience to make a better way to store beer. With a GrowlerWerks growler your beer will always taste exactly how the brewmaster intended.

Our mission at GrowlerWerks is to make a growler that works. After testing all the options available, we realized that nobody had cracked the code on a pressurized growler that works. So we designed the uKeg....and the rest is history.
