#1 The Catalyst Fermentation System

The Catalyst Fermentation SystemCraft-A-Brew’s The Catalyst Fermentation System is, in our professional opinion, the best conical fermenter currently in production in the market. It looks professional and has a 3″ Trub Trap Butterfly Valve that separates sediment, eliminates transfers, and allows you to bottle straight from it, making it a very fast fermenter indeed.
Conical fermenters like this allow for the malt extract, hops, and beer sediments to settle within the bottom cone and make it that much easier to transfer clean lager. It’s like what they say: Once you choose conical fermenters, you never go back.
The Catalyst’s tank is made from food-safe, BPA-free polymer, which is perfect for the storage of alcohol and other ingredients like grain, liquid malt extract, dry malt extract and yeast.
With an incredibly sturdy stand made with I-beam and honeycomb construction, a squat 6.5-gallon tank and a 3″ Trub Traps Butterfly Valve, the Catalyst is an efficient and practically indestructible system that fits easily under a table or on a countertop. The Trub Traps can work with any large-mouthed mason jar, making it super simple to separate sediments or catch and store viable yeasts.
This company makes other brewing supplies such as beer kits, recipe kits and kettles to support you while you experiment with craft beer recipes.
I highly recommend The Catalyst, whether you’re a beginner or an advanced brewer. It has certainly changed the game for home brewers everywhere. Check out the quick demo video below of this bad boy in action.


#2 SS BrewTech Brew Bucket Fermenter

catalyst fermentation tank, gal conical, without brew kettle, beer recipe kits at a brewery, no leg extensions

The SS BrewTech Brew Bucket is one of the best conical fermenters that money can buy. Like Blichmann’s Fermenator, it also has a stainless steel conical-shaped design, which makes fermenting with this equipment a quick and easy task.
Although there are similar beer fermenters out there to the SS BrewTech tank, the alternate one only comes in a 7-gallon steel conical fermenter model, which is why this is a better choice for your home beer brewing process and kegging systems.
The entirety of its body tank and components are made of food-grade stainless steel, and the pro tank includes a sealable lid which also has a hole for a blow-off ball valve and/or tubing. It also has stainless steel retractable food-grade handles that can be used to move the fermenter when it is full of beer. A quick tip: Don’t forget to monitor the fermentation temperature by doing a cooling temperature control for a better brew.

#3 FastFerment Conical Fermenter

Brew Bucket Fermenter (gal conical), racking, fittings, without stand, beer recipe kits, no leg extensions

The FastFerment conical fermenter is an amazing option for anyone who wants to easily brew small batches of beer, hops, and kegs. It only comes in one size, which makes shopping easier because you won’t have to choose between a lot of different sizes anymore.

This 7.9-gallon conical fermenter can take care of every single stage of the fermenting process–that means no transferring, no siphoning, no secondary sanitization, no extra accessories kits, etc. Extract beer from this fermenter right to your beer bottles without any sweat at all!

The FastFerment conical fermenter also contains a nifty detachable collection ball valve that collects the all-grain yeast (or beer yeast) and debris during the beer brewing process, which completely eliminates the need to transfer to a second vessel and makes cleanup easier. Don’t forget to always monitor the fermentation temperature to get a better brew.

If you’re on a budget and can’t quite justify buying the stainless models, this 7.9-gallon conical fermenter is a good alternative.

FastFerment makes other beer brewing supplies and equipment that can help you in your craft beer experiments so we recommend that you check out their other offerings as well.

#4 BrewDemon Conical Fermenter

BrewDemon Conical FermenterThe BrewDemon Conical Fermenter is a nice little beer brewing system that’s a good bang for your buck if you’re a home brewing enthusiast who’s not looking to brew a large batch of beer anytime soon. Touted as the world’s first small batch conical fermenting system, the BrewDemon will allow you to brew 2 to 2.5 gallons of beer, hard cider, wine and mead–just enough for you and your closest buddies.

Its conical design allows you to easily transfer your beer into bottles without spilling it, while making sure that the trub (beer yeast, malt extract, hops, and other beer sediments) stays securely at the bottom. It doesn’t require an airlock but it includes a CO2 venting system, adjustable flow spigot and stick-on temperature gauge.

This conical fermenter is made of food-grade PVC plastic that’s both heat-tolerant and phthalate- and BPA-free, so you won’t have to worry about your brew taking on flavors that are different from the flavors you intended. All in all, this is another good choice for brewing all your craft beer recipes right in the comfort of your home.


#5 Blichmann Conical Fermenter

Conical fas fermenter (no brew kettle)

We’re always striving to find the best and newest beer brewing equipment for you, and that’s why we want to recommend another one–The Blichmann Conical Fermenter. This fermenter comes with a hose and a valve and is one of the most popular and coveted conical fermenters out there in the market.

This beast of a fermenter is made from solid stainless steel and contains pretty much every feature you would want in this kind of equipment.

It also comes in a variety of sizes to suit your needs–from a small, 7-gallon unit all the way up to a humongous 42-gallon unit.

Its size is an obvious advantage over the carboy and the FastFerment, both of which come only in smaller sizes. If you want to go for a bigger conical fermenter I highly suggest you go with this one because it definitely is one of the best out there.

3 Honourable Mentions

These fermenters might not have a conical design, but we liked them so much that we can’t help but add them to this list. Maybe they’re not as fancy or as convenient as our recommendations above, but they have their own useful features that make them worth your hard-earned buck, and they can definitely do as good a job as any conical fermenter out there.

#1 Big Mouth Bubbler

beer fermentation time, gal conical, without beer recipe kits, fittings, racking, no leg extensions

The Big Mouth Bubbler is very similar to a carboy that has extra features added to it.

These features, in my opinion, are what makes the Bubbler worth splurging for, especially if you compare it with other standard beer brewing equipment.

Big Mouth has designed their beer fermenters to incorporate a spigot at the bottom for a siphon-free design. This makes it extremely easy to attach a hose and transfer the wort to a secondary fermenter or bottling bucket before you tapping your wine, cider or beer into bottles. It also has a dual port lid that opens up a lot of other possibilities for your home brewing needs.

The Big Mouth Bubbler comes in two different sizes: 5 gallons and 6.5 gallons. If you’re sold on the carboy-style models, then this fermenter is a nice step up and I highly suggest going with one of these. Now, let’s get that wort ready, shall we?

#2 Kegco Carboy

Glass Fermenter (Gal Conical), bottle caps, without beer recipe kits, fittings, racking

One of the most common beer brewing equipment out there is the carboy. This product looks like a large glass bottle and ranges in size from 5 gallons up to 15 gallons. It is definitely one of the more inexpensive fermenter options out there, especially when compared to stainless steel fermenters that can cost quite a lot.

I find this option to be much better than its plastic counterpart because it doesn’t hold odor or bacteria and it doesn’t scratch, discolor or break down over time. It also allows you to have a view of the ale, malt extract and beer yeast while they’re being fermented.

I would suggest picking up a bubbler airlock if you decide to go with this product. Airlocks will allow the gasses to escape while still maintaining a tight air seal, and this will prevent contamination during the fermentation process.

You may also want to pick up another one of these if you’re planning on having a secondary fermentation system. This product is an amazing way to get started on your own recipe-testing and beer brewing process at home for very little money.


#3 Northern Brewer Fermenting Bucket

Fast fermenter bucket, without beer recipe kits and stand, at a brewery, fittings

This fermenting bucket is one of the cheapest, if not the cheapest, way to ferment your beer. But please don’t set your expectations way too high. As you can see, it’s only a bucket!

The product can also double as a bottling bucket (which is actually the more common of using it). From our point of view, if you plan to go this route, make sure to go with the siphonless model. Doing so will make the beer brewing process a whole lot easier for you, especially if you’re just starting out with home brewing.

The Northern Brewer Fermenting Bucket also comes with the option to add a lid, an airlock (to keep the lid in place), a thermometer (to check the beer temperature) and a spigot–all for a very low price.

If you are still deciding on which home brew fermenter stand to grab, I would consider going with one of the other options such as the Big Mouth Bubbler or the FastFerment. There isn’t a whole lot of cost difference between the choices, but the ale and beer batch brewing benefits are excellent. If, however, you are set on this fermenting bucket, you might want to make your beer brewing process easier by grabbing one or all of the extra accessories mentioned above.

There are plenty of different beer brewing brands and manufacturers out there that deliver very similar products. However, not all of them are created equal. Whenever I make a purchase, I always try to grab the best and the newest equipment that I can afford. That way, I won’t be forced to upgrade to something better a few weeks or months down the road. Believe me, this technique will save you a ton of time and money in the long run.

With that being said, I would recommend going with The Catalyst Fermentation System. I know this is a little more expensive than the other options I’ve talked about, but remember that you get what you pay for. If you’re on a tight budget on the other hand, I would suggest going for the Big Mouth Bubbler,

Now that you have a list of the best fermenters out in the market today, from plastic to stainless steel to glass variants, you are now ready to explore your brewing (or even winemaking) techniques! Get that wort going, fill up those beer bottles, and enjoy your brew!
