Want an easy-to-use, stainless vessel that ferments and carbonates? This 58L/15.3 Gallon keg has been modified to allow you to do both! The top is fitted with a large 4 inch tri-clamp lid with two ball lock posts and a pressure relief valve. You can use this vessel to ferment, carbonate, serve, or push the beer through a filter. The posts are recessed which allows you to stack these kegs up to 4 high. A 4" T.C. end cap with pre drilled hole is also available (H691), which can be paired with a #3 stopper and airlock.

Depending on how long it will take to consume the finished beer, we recommend using two kegmenters, one for fermentation and one for carbonating and serving. After fermentation, there will be a large trub cake at the bottom of the vessel. Leaving finished beer on the trub for too long (2-3 weeks) may eventually lead to off-flavors. Check out our ball lock jumper line (KEG575) to easily transfer from one kegmenter to the other. Also consider our beer filter kit (FIL40), which will allow you to filter the beer during transfer.


  • Rated up to 2.5 BAR (36 psi)
  • 4" T.C. lid with ball lock posts
  • Floating dip tube
  • Stainless steel 1.8 mm thick


  • As a stainless steel fermenter that is easy to clean
  • Great choice for 10 gallon fermentations
  • Easy to pressurize the kegmenter after fermentation to push through a filter and into another keg
  • Fermenting under pressure, allowing CO2 to exit via the relief valve, reduces esters and fusel alcohol production allowing you to ferment at warmer temperatures
  • Distillation - with the addition of a T.C. reducer and condenser (H701 / DS120 / DS130)
  • As a cellar keg for topping up barrels


Warning: Always depressurize keg before removing lid.

Does not come with spunding valve show in example photo. See FIL42A.

10gal fermentation and 4 in column upgrade.
Donald M on Jan 5, 2021
I need to be able to ferment a 10 gallon batch under pressure. This is the most durable product I have found for the price. The cleaning of stainless steel is much more effective than plastic.

Multifunctional kegs
I use these for everything. Pressure fermentation, brite tank or serving vessel. They are awesome! Easy to clean with the 4" triclamp ports.

Great quality
I bought this for fruiting barrel-aged sours. Works well and it's easy to clean when it's time to transfer off the fruit. I actually swapped the floating dip tube for a straight dip tube coupled with a Scott Janish-style dip tube screen. This combo prevents clogged dip tubes and results very little loss due to beer being locked up in the fruit mass.

Pressure Fermentation with the Kegmenter
The Kegmenter works great, just as I had hoped. I use it for pressure fermentation of my lager style beer. I then pressure transfer to my 5 gallon serving kegs after the fermentation is complete. It is strong and durable. No need to worry when cleaning and transporting like you do with glass fermentors. The built in handles make it easy for two people to carry if you have a full 10 gallon batch going. Also, it is very easy to clean and sanitize. The large opening is a big help. I recommend it to all.

Super versatile
I have purchased 3 of these kegs and will be purchasing more soon. They are versatile in that I've used them as brite tanks, filling tanks, and holding tanks. They are easy to clean and transport.
I would prefer the straight stainless steel beverage tube vs the floaty ball tube/hose though.

Customer service is always top notch.

Perfect in every way. I wish for a 1/4 keg slim with a 4” access.

Solid, solid, solid!!!
These things are champion! Build quality is superb and finish is perfect. They are ideal for pressure fermenting ten-gallon batches and very easy to clean. This is what you need when you step up from single batch brewing. Get two. You're going to do it eventually anyway so go ahead and save yourself the frustration. Absolute best value in fermenting.
