Frequently Asked Questions
How long does the beer stay fresh?
Like a mini keg, the uKeg will keep your beer fresh for weeks.
How long does the CO2 cartridge last?
The gas cartridge dispenses one uKeg full of beverages, with some pressure left over that you can use to clean the growler with water and pour through the tap.
What type of CO2 cartridges does the uKeg cap use?
All uKeg growler caps use standard unthreaded food-grade cartridges. Our regulator cap can accept 8g or 16g cartridges. Check out our guide to Approved CO2 Cartridges.
Where can I get the CO2 cartridges?
Food grade gas cartridges are readily available on our website, online via Amazon, and at kitchen stores and PerfectWerks retailers.
How much does the CO2 cost?
The 8g cartridges can be found on Amazon for as low as $0.50 each. We list them here on our website for as low as $1 ea. With about 5 x 12 oz. drinks in a growler, that's just 10-20 cents per fresh pour.
Where do I fill my growler?
With an internal volume line, you can take your uKeg growler to any store or bar that currently fills growlers. Growler laws vary state-by-state, and are rapidly changing to remove old restrictions. The Brewers Association provides a helpful directory:
Can the uKeg be used for other carbonated beverages besides beer?
You can put soda, water, or other carbonated beverages in the uKeg, such as sparkling wine or homemade cocktails (just add rocks glasses for a party). One of our team members even uses it for carbonated apple cider for his kids!
Does the uKeg come with a warranty?
Yes, each uKeg comes with a 1-year warranty for parts and defects when purchased from an authorized reseller. You can register your warranty here on our website. We also have a tech support team that can help you, and we offer spare parts and accessories. The uKeg is built with high quality parts and will last a lifetime with proper maintenance.
How can the uKeg be cleaned?
Cleaning the uKeg is easy. Click here for instructions. Rinsing with warm water after each use is the best practice. Any leftover gas can be used to flush the tap with water, but turning the uKeg upside down works too. The cap can be removed to easily clean the inside of the stainless steel vessel. Click here to buy food-safe growler cleaning tabs. The tap assembly, sight glass and pressure gauge can be fully disassembled for deeper cleaning when needed.
What pressure range does the regulator cap provide?
We designed this version of our regulator cap to go between 0 and 22 psi. Zero psi corresponds to the "off" position when the regulator is closed, and the cap will not dispense the contents of the CO2 cartridge. The off position is for taking the cap off and on the vessel. 22 psi may be good for force carbonating home-brew or other beverages, or highly carbonated stuff.
Can the uKeg 64 be used to force carbonate Home-brew?
The uKeg 64 is capable of force carbonating beer and other beverages. Turn your homebrew, cider, wine or juice into a delicious, carbonated beverage within just 2-3 days. To ensure you have enough CO2 onboard we recommend using a 16g cartridge for the uKeg 64. The uKeg 64 comes standard with an 8g cartridge holder and additional 16g cartridge holders are available on our website.
Can the uKeg 128 be used to force carbonate Home-brew?
The uKeg 128 currently uses a 16g CO2 cartridge. This may be sufficient, however, we're not confident that's always enough CO2 to both fully carbonate and dispense your beer to your liking. To ensure you can fully dispense, the cap can be easily removed to replace the cartridge after carbonating and before dispensing.
Can the uKeg be used with nitrogen cartridges?
Nitrogen does not come in cartridge size that will fit in the uKeg. You can however use N2O cartridges which will come in 8g and 16g volumes.
Can the uKeg be used for non-carbonated beverages like draft wine?
If you use an inert gas like argon instead of CO2, the uKeg can dispense non-carbonated beverages just fine. For lightly carbonated beverages such as beer served on "Nitro", you can set the pressure low between 3-5 psi which is just enough to dispense the beer without overly carbonating. N2O can also be used for cocktails and other beverages.
Can the uKeg Nitro be used for carbonated drinks?
No. The uKeg Nitro is optimized for cold brew coffee. Carbonated drinks will pour overly foamy and result in a flat, non-carbonated experience.
Can the uKeg Nitro be used with N2(nitrogen)?
No. N2 is not available in cartridges large enough to be used with the uKeg Nitro.
How does the sight glass work?
Beer (or other beverage) travels through an inner dispensing tube within the sight glass, that connects to the tap, while the sight glass is an extension of the vessel with openings at both the top and the bottom. The pressure gauge measures pressure near the bottom of the vessel.
Can I use a regular size tap handle with the uKeg?
The tap is a miniaturized version of a standard tap and will not fit into a standard tap handle. A customer adapter is needed if a standard handle is to be used.
Can I place an order to be shipped internationally?
We are in the process of making international shipping possible to various countries. If your country is not allowed and you choose to try and use a third party shipping company we are in no way responsible for paperwork or ensuring delivery once it leaves our facility.
FAQs for Customized Products:
What are Customized Products?
For some of our products, we offer customization. Customization can either be full color printing or laser engraving. Customers are able to either upload their own imagery, graphics, logos... etc, or add custom text to our products.
Color Printing vs. Laser Engraving:
Color printing is just as sounds - a process of laying and adhering multiple colors of UV ink over a product's surface. This process allows for images, photos, singles color graphics to be added to a space on the surface of the product. As it is very durable, cleaning and care must be taken to ensure the quality and longevity of the printed image.
Image File Requirements for Color Printing
JPG/JPEG, PNG, and PDF images are accepted. A minimum of 150dpi and minimum of 300px horizontal or vertical are required. PerfectWerks is not responsible for image uploads that infringe on Trademark or Copyright rules and/or regulations.
Laser printing is a process of removing a thin layer of the surface material off of a product to reveal the material below. Because of this process, the revealed material shows as a silver color stainless steel. Gradients or color "fades" on an uploaded image or graphic will not be accepted for laser engraving.
Image File Requirements for Laser Engraving
JPG/JPEG, PNG, and PDF images are accepted. One-color graphic with a white or transparent background. A minimum of 300dpi and minimum of 300px horizontal or vertical are required. PerfectWerks is not responsible for image uploads that infringe on Trademark or Copyright rules and/or regulations.
