The Hop Bong is a versatile pressurizable tri-clamp accessory, capable of not only dry hopping oxygen purged hops into fermenters, but also as an inline carbonation/oxygenation accessory. Load up the Hop Bong, flush it with CO2, purge out oxygen with the handy PRV on top, then simply open the Butterfly Valve to inject your beer with a 6 oz payload of dry hops.

If you're an existing FermZilla Conical or All Rounder user and you already own the Pressure Kit with 2x Ball Lock Caps and floating dip tube, check out the Hop Bong Upgrade Kit.

The 3 Pieces of the Hop Bong Pressure Pack:

  • Pressure Kit
    • ​The Pressure Kit includes two Ball Lock Caps with the Floating Dip Tube and Filter Attachment. These pieces allow you to pressure transfer finished beer out of the fermenter into kegs or a bottling bucket, or you can carbonate and serve beer directly from the FermZilla.
  • Tri-Clamp Pressure Lid
    • Replacing the standard lid with the FermZilla Tri-Clamp Pressure Lid provides you with a 2" T.C. port at the top of your fermenter. This will give you an opening to add dry hops or other additions without needing to remove the entire lid. Take off the butterfly valve to add your yeast pitch, and when you're ready to add flavoring additions when fermentation is complete, drop them in oxygen-free via the Hop Bong. PCO1881 threaded ports are there for your Ball Lock Caps, as well as undrilled ports for an optional Thermowell and/or Temp Twister cooling coil.
  • Hop Bong 
    • Load up the Hop Bong and add CO2 to purge your hop charge of oxygen. This kit comes with a third Ball Lock Cap to introduce CO2 directly to the Hop Bong, as well as a pull ring PRV to release pressure and purge oxygen. Once you've flushed your hop charge with CO2, open the butterfly valve to inject your beer with up to 6 oz of hop pellets.

Hop Pellet Capacity: 150–180g (5.2–6.3 oz)

Kit Includes:

  • FermZilla 2" T.C. Pressure Lid Starter Kit
  • 2" Hop Bong
  • 2" FermZilla Tri-Conical Butterfly Valve
  • Floating Dip Tube with Filter Attachment
  • Red PRV & PCO1881 Cap Combo
  • Yellow Ball Lock Cap
  • (2) Red Ball Lock Caps
  • (2) 2" Tri-Clamps
  • (2) 2" Silicone T.C. Gaskets

KegLand Part Number: KB10897

Installation Note: For best performance, ensure there is not an excess amount of slack when the silicone dip tube is installed and shorten it if needed. With the floating dip tube installed on your empty FermZilla, you ideally want the dip tube to hang freely with just enough length for the end of the dup tube to touch the bottom of the tank.

Warning: Always depressurize your system COMPLETELY before removing fittings from your fermenter.

Is there space on the tri-clamp lid to accommodate the "Temp Twister Cooling Coil" (FE139)? The photo is pretty dark but I think I see enough space to drill a couple holes and fit the coil.

can I keep in my freezer (fermentation chamber) with just the butterfly valve uncapped (2nd T.C. with pressure relief cap)? It looks like on my All Rounder that it will be too tall for my freezer (25.5-26 inches deep) if I need to clamp on the cap. I believe the butterfly is what actually keps the fermenter sealed - is that correct? I do of course have a spunding valve so the pressure relief is covered there (with no failsafe PRV - but since mostly NEIAP I have the valve fully open as I am not pressure fermenting).

I've ordered already - but hope not to have to have my All Rounder "tilted" in order to fit in the freezer,

Expensive but great
About the easiest way to dry hop with pretty much no oxygen. Just add your hops to the bong, pressurize and purge with the PRV, pressurize the bong one last time to a higher pressure than the fermenter, and open the butterfly valve to drop the hops in. No more fussing with magnets, timing your dry hop and hoping the yeast scrubs oxygen, or keg hopping. You can also use it to add gelatin, purée to sours, just about anything you can think of (just clean it well!) The hop bong also has lots of other cool uses as well (see Kegland's video on YouTube, Key shows a bunch).

Also, if you have multiple Fermzillas, you only need to buy this entire kit once. Otherwise you can just buy the lid with the Triclamp fitting and a 2 inch butterfly valve, and just swap your hop bong around as needed. The only downside is the price, it's actually more expensive than the actual All Rounder, but it's super worth it in my opinion and will last a lifetime. Cheers!
