Updated Fermzilla All-Rounder 30L - Quality Plastic Fermenter

Review by Johnny Bavlsik on 2/22/2026

*This review is for the recently updated Fermzilla All-Rounder 30L.* The new lid with handles works well, and is much more convenient than using a strap wrench, which I needed for the old version of the fermenter. The integrated base makes handling the fermenter awkward for sanitizing / cleaning, and I would prefer if it wasn't permanently attached to the fermentation vessel. The weighted dip tube filter works well, but the weighted cap is a bit difficult to pry off, and it would be nice if there was a small notch or some other feature to pry it off. To attach the volume reference sticker, I recommend that you weigh out 5 gallons (or your normal batch size of water, at 8.34 lbs per gallon), then align the sticker at the volume and place it along the line / seam on the side of the fermentation vessel, cutting off the bottom at the integrated base. Overall, the fermenter is improved from the previous revision and worth buying, despite a couple issues.

All Rounder

Review by James on 11/27/2023

The Fermzilla 30L All Rounder with a Pressure set up and thermowell is an excellent solution to Pressurized Fermentation. This is the second All Rounder I have purchased with this set up. When used properly, through experimentation is, the ideal solution for an economical and exceptional brewing experience for the experienced brewer.

Easy as a bucket but WAY better!

Used a corny keg in the past for pressure fermenting. They are a pain to clean and I would have to short my 5 gallon batch. The Allrouder is easy to clean, doesn't hold a smell like plastic buckets, great volume or a 5 gallon batch, and great to see what is going on with the ferment.

Easier to clean

Review by Steve R on 3/23/2023

I bought one of these as soon as I saw it. I've been using the Fermzilla Tri Conical fermenter for years and love it except that all the fancy stuff for yeast collection and dry hop addition is hard (but essential) to clean and rarely used. This unit does not have that problem. Only issue: it's top-heavy and falls over easily when empty.

Fun Option

Review by Robb on 6/24/2021

This fermenter design allows for a lot of fun. Air tight, closed transfers, spunding, floats (water pool temp control), & still small enough to transport fairly easily. Quickly became my favorite option, and at a pretty crazy cheap price. The 2-year expiration isn't great, but $50, 2 years isn't bad (and I think that is mainly for the high-end pressure rating if you plan to carbonate in it, which I don't). Yes, edges of handles are rough/sharp, and I filed the edges down before assembly. Overall, if you already keg/have a CO2 tank, this is a great option for those of us that like to watch the fermentation.
