FermZilla All Rounder Fermenter - 7.9 gal. / 30 L

FermZilla All Rounder Fermenter - 7.9 gal. / 30 L

Item currently out of stock

The FermZilla All Rounder is the most affordable pressurizable fermenter on the market. Although it doesn't feature a dump valve like the FermZilla Conical, the All Rounder carries the same pressure rating, making it an absolute steal if you're looking to ferment under pressure, perform pressure transfers, or want to carbonate and serve directly from the fermenter. The All Rounder is made from super smooth PET that's easy to clean, and the simple design means no nooks or crannies for microbes to hide. With a 4.75" lid opening, you'll have no trouble getting your arm inside to scrub away stubborn krausen rings. As with all FermZilla fermenters, the lid features molded drill locations that make installing accessories like a thermowell or Temp Twister Cooling Coil a breeze.

In order to unlock the full potential of the All Rounder, you'll want to pick up the 55L FermZilla Pressure Kit. The silicone dip tube will be a little long, but you can cut it shorter to the appropriate length. The pressure kit is available with either stainless or plastic ball lock caps.

Why MoreBeer! loves the All Rounder FermZilla:
  • Super smooth PET makes cleaning very easy.
  • Pressure rated lid and PET material make for a better oxygen barrier than fermenters made of HDPE.
  • Lightweight and easy to move around, yet strong enough to be considered shatterproof.
  • The 4.75" lid opening makes it easy to get your arm inside and clean after use.
  • The lid is designed for the easy installation of accessories such as a thermowell or cooling coil.
  • Price! A pressurizable fermenter in this price range is an incredible value, and it opens the door for many cold-side processes that can't be done in a normal carboy or plastic fermenter.

  • FermZilla 30L All Rounder Fermenter

Ability to pressure transfer and spund.

Going to give fermenting under pressure a try. I think this may possibly help to do a better job producing a NEIPA.
Michael Postiff on May 15, 2020

The widest part of this fermenter is 13.9"? It's hard to tell from the pictures if the holding rack sticks out further than the sides of the fermenter.
Derek Stanton on Jan 30, 2020
BEST ANSWER: If you look closely at the second and third pictures, notice that the stand is shown in two different configurations. Inserting the All Rounder into the wider base allows it to sit lower, but it's not wider than the All Rounder itself. Using it with the narrower base allows the All Rounder to sit higher. I've seen line drawings online that give exact width and height measurements for both configurations, up to both ball locks and the air lock. I'd insert a link but MB does not approve.
Does the stainless steel pressure kit for the 55l work with this as well?
Adam Lowery on Jan 16, 2020
Is there a carrying handle included ornis the strap available?
Adam Lowery on Jan 16, 2020
BEST ANSWER: Hi Adam - the All Rounder 30L and 60L units include a stainless steel carrying handle similar to a carboy handle. There is also a carrying harness that will be released later this year, which attaches to the stand so the whole fermenter and stand can be picked up and moved at once (FE149).
Does the thermowell work with this?
Adam Lowery on Jan 16, 2020
BEST ANSWER: Yes. Although the thermowell is quite a bit longer than necessary. It can be cut down to size easily with the proper tools.

You'll also need a step drill bit to create the proper size hole for fitting the duotight thermowell gasket into your Fermzilla cap.

Fantastic fermenter. I use it to ferment under pressure and transfer O2 free. Been looking at getting one for a while very happy I pulled the trigger. Definitely going to be buying another one. Highly recommend it.

Worth every penny.
I have been a fermentasaurus and fermzilla fan from the minute they hit the market. The all-rounder gives the benefits of fermenting under pressure without the hassle of cleaning the butterfly valve and at a low price. I can still harvest yeast the old fashioned way from the cake if I want to.Have not tried dry hopping in it yet.

All aRound great fermentor
On my second batch with this fermentor.
Compact size
Light weight
Easy to clean
With the pressure kit it is easy to do beer transfers directly to a keg or bottles, take samples for SG measurements all without the worry of contamination or oxygen.

No dislikes but the top is a bit hard to get off but using keg lube on the o-ring seal helps.

So far, so good!
I ordered the allrounder in order to ferment beer under pressure. I had a brew ready to be transfer to a secondary fermenter. I transfer the flat beer to to the all-round and put it under 13PSI of pressure. I also brew an NEIPA and I am doing an primary fermentation under 11PSI. Both vessels are holding pressure perfectly, so far. I gave it a 4 stars because the pressure kit (ball lock) that I ordered with the allrounder, would not fit my beverage out ball lock. I had two extra female threaded ball lock for the beverage out port. The extra ball lock fittings work great. Disappointing that I had to purchase two extra threaded ball locks, which cost me an additional $21.16.
Primary fermentation under 11 PSI
Spundit valve
Secondary/clarifying  fermentation 13 PSI

Great first foray into pressure fermentation
I bought two of these to replace my Big mouth bubblers. So far they seem great. They are large enough that I don't have to worry about blowoffs with my batch size (5.5 gal) and once the pressure kit gets here I will be using that to transfer and carb my beers.

All in all super nice and well thought out fermenter, it feels like a nice step up from the BMBs.
