DO NOT

DO NOT USE UKEG WITH LIQUIDS ABOVE 120 DEGREES F.

Do not open sleeve when cartidge contains pressure.

Do not turn off pressure when uKeg is full. Doing this does not save nitro gas.

Brewing Nitro Cold Brew

1. Fill 2 bags with 60g (~3/4 cup) with course ground coffee each.

2. Tie knot with bag strings.

1. Place both bags in uKeg (knot facing upward).
2. Fill with water to “Brew” Line (~1.25 liters).

5. Place in refrigerator for 12-24 hours

6. Pull out bags.
7. Add additional water to “Fill” line (~.75 liters).

8. Charge cap with a fresh nitro gas cartridge.
9. Tighten cap on uKeg Nitro.
10. Turn dial to “Infuse”. 

11. Shake for 1 minute to infuse nitro gas in the cold brew.

Pro Tips

For a Stronger Cold Brew:

    • Use more coffee. Each bag can hold up to 1 cup.
    • Brew longer (up to 24 hours).
    • In step #3, fill with water above the “Fill” line. This leaves less dilution water to add later.

For a More Nitro Infused Cold Brew:

    • Make sure your brew is as cold as possible before infusion (use some ice in step #5 when diluting).
    • Shake longer.
    • Leave the pressure setting on “Infuse” overnight.

Basic uKeg Maintenance

  • Use 1.5mm allen wrench (provided with new handle).
  • Loosen set screw on handle and pull straight up.
  • Do not twist.
  • Install a compatible handle in reverse order.

Caring for Your uKeg's Color Finish

The surface and color of your uKeg is a durable coating that is bonded to the stainless steel bottle in a thin layer. Your coated uKeg should not corrode. For best results when cleaning, please follow instructions below:

  • To clean the surface, gently wash with soap and water or mild detergents.
  • To remove spots, discoloration, or minor blemishes, gentle rubbing with a soft cloth and water is recommended.
  • Do not use polishing compounds or abrasive pads to polish the color surfaces.
  • Spot cleaning this way can remove the finish which can later lead to corrosion.
  • The ukeg’s finish, while strong, is not impervious to scratching, so if you want it to look nice, treat it nice.

Cartridge Seal Replacement

1. Squeeze tabs and pull retainer out.

2. Inspect cartridge seal for cracks or defects. Replace if needed. Note orientation when removing.

3. Insert new seal in orientation shown.

4. Reinstall retainer and seal.

5. Push retainer down until both tabs click outward.

Helpful Tips

Inspect Periodically

Make sure retaining tabs are fully pushed out and seated properly.

Cap O-ring should be tight and smooth.

Make sure O-ring is installed as shown and free of damage.

Pressure off is counterclockwise.

Helpful Tips

Replace nitro gas cartridge after every use. Any remaining gas can be used to flush your uKeg with clean water.

  • Long term storage of your uKeg with a cartridge installed will reduce cartridge seal life. Remove cartridges promptly after discharge.
  • The cartridge seal is designed to be resilient, but may be damaged from overtightening or sharp cartridges. Your uKeg came with 1 extra cartridge seal.
  • The cap o-ring is designed to be resilient, but may become damaged or loose from over-tightening.
OPTIONAL: Applying a light coat of silicone grease to o-rings will extend their lifetime.
