Hands on Review: Fermonster Fermentors

Updated: March 19, 2025

This review is by Homebrew Finds Contributor Brad Probert. Brad is an engineer, expert homebrewer and experienced reviewer. Grab a link to Brad’s website at the end of this review.

Fermonster PET Fermentor

With all of the fermentor choices out on the market, there are plenty of good reasons to not be fermenting in that plastic bucket that came with your starter homebrew kit. Most of us make that realization when we can no longer fool ourselves into calling it “white”, and it carries the aroma of all the previous hop varieties it’s seen. PET Plastic fermentors are the logical next step up from the HDPE plastic buckets.

PET Is far less porous than HDPE. Because of that, it makes for a great oxygen barrier. As a material, HDPE passes through 50x the amount of oxygen over a given time than PET. So PET makes for better long ferments like if you’re lagering (or are just the forgetful type). Glass is an even better oxygen barrier, not allowing any oxygen to permeate it. But from a practical perspective, just like Coca-Cola figured out, glass is heavy and creates a nasty mess when you drop it. PET Is also cooler than that plastic bucket because the fermentor is clear, which allows you to view the exciting chemistry going on inside your brew.

The Fermonster comes in different sizes and options. They come as big as 7 gallons or as small as 1 gallon. And also intermediary sizes of 6 gallons and 3 gallons. You can get it without a spigot or with one if you want to do gravity beer transfers instead of using a siphon.

MoreBeer 6 Gallon Food Grade Bucket w/Volume Markings – $11.99 + free ship eligible, limited availability

6 Gallon Food Grade Bucket from MoreBeer

More Info

From the product description, check product page for current description, price and availability:

The most affordable 5-gallon batch beer fermenter you’ll find!
Food-grade plastic buckets make a perfect starter fermenter for beginner brewers—simply add a lid with stopper and airlock
Once you’ve upgraded to a carboy or other fermenter, the bucket will remain a reliable brewing tool for cleaning and sanitizing purposes
External volume markers provide a convenient reference point when filling the bucket with water to make cleaner or sanitizer solution

A food-grade six gallon plastic bucket perfect for all kinds of home beer or winemaking activities. Plastic buckets are often used as a fermenter, bottling bucket, or even sanitizer bucket. We go through thousands which helps keep our price down. If you want to use it as a fermenter you will also need to pick up the optional lid, stopper, and airlock. This bucket is also available in a version that includes a spigot (see recommended products below).

If you use this plastic bucket for fermentation be sure to use care when cleaning. Do not use any abrasive pads that would scratch. Once you get a scratch in a plastic bucket it is very hard to sanitize. This is also why we don’t recommend storing equipment in a bucket between uses as a fermenter. A hot PBW soak is often a perfect way to clean a bucket, followed by a Star San soak for killing bacteria.

Bucket has external volume markings up to 5 gallons. 17.5″ H x 12″ Ø

Limited Availability Deal of the Day: As of this posting, this is marked down to $11.99 as a MoreBeer Deal of the Day. Shipping is also free to addresses in the contiguous US with most $59 Orders.

In my opinion the original ITC-308 was and is a game changer as far as homebrew temp controllers. In comparison to available controllers available at the time the ITC-308 was released, it offered loads more features, including dual stage control, for a fraction of the price. Game changer! The addition of Wi-Fi control and monitoring to this great controller has made a great temp controller even better. Check out our Hands on Review of the ITC-308.
