NC Keg Dry Hopper User Guide

Please follow these instructions carefully when using your NC Keg Dry Hopper. Make sure you push in the silicone stopper firmly before installing the dry hopper into your keg. You should thoroughly clean and disinfect the Dry Hopper before using it.

If you are using the Polyethylene version of this product, you should not pressurize the keg to greater than 1 bar when the bottle is installed in the keg. This will prevent excessive collapsing of the bottle.

Note: the NC Keg Dry Hopper is compatible with both NC and CC type kegs. Please note that the gas valve on the included lid is for NC disconnects only.


1. Prepare your keg for dry hopping. On the liquid side of the keg you should cut your liquid dip tube about 3 cm shorter to prevent sucking up hop material when transferring the beer out of the keg. Alternatively, you can install a floating dip tube set (shown here, not included).
2. Then install the shortened gas dip tube, included with the set, in gas valve of the keg. because of the shortened Liquid tube or floating dip tube, the liquid cannot be completely drained from the keg in step 14. The short gas dip tube allows full drainage.

3. Fill the keg within 1 cm from the top with water or diluted Starsan. When installing the Dry Hopper, excess liquid will flow out of the keg leaving very little air remaining inside. This will allow you to purge the keg effectively of oxygen.

4. Place the stopper loosely in the cylinder. Connect your CO2 to the lid and turn on the gas, allowing the chamber to be purged of oxygen for 20-30 seconds.
5. When purging is complete, turn off the gas and push the stopper firmly into the cylinder. There should be about 15mm of stopper sticking out of the tube.
6. Insert the Dry Hopper into the keg as shown. The liquid valve should be on the near side so that it does not interfere with installation. The lid oval should be 90 degrees to the oval opening of the keg.
7. Tilt the lid so that the pressure release valve passes into the keg.
8. When the pressure relief valve is in the keg, turn the lid 90 degrees
9. Now the lid is in the proper position for sealing
13. Close the lid by pushing the handle down completely.
14. Drain the liquid out of the keg using CO2 from your gas tank or using fermentation gas from your fermenter.
15. When the keg stops draining, move the gas to the liquid connector (use a liquid disconnect) and connect a gas connector on the gas side. Turn the keg upside down and turn on gas at low pressure to allow the keg to drain completely. Tilt the keg towards the gas outlet to ensure proper drainage.

Removing the dry hopper

1. To remove the dry hopper from the keg, lift the handle. Grab the PRV release ring to make sure it is out of the way. While pulling up on the lid handle, push down on the PRV while rotating the lid.
2. Make sure you lift by the handle while rotating the lid. At about 45 degrees the lid should be coming out the keg already.
3. Finish rotating to 90 degrees while lifting and the dry hopper should come out easily.
