The 8 Best Conical Fermentors For Homebrewing

Most homebrewing beginners start their brewing journey with very little equipment. They usually use glass carboys and a simple plastic bucket for the fermentation phase.

Although this is one of the cheapest way to store your fermenting beer, they are not really made for brewing. 

In addition, glass carboys can break easily and there is a high risk of not just ruining your beer but also hurting yourself in the process.

In order to avoid this, there is good brewing kit out there that resembles the fermentation tanks which are used by large breweries. But don’t worry, these fermentors are not as big as with a commercial brewery.

We had a look at some of the best conical fermentors for homebrewing of batches of around five gallons.

Here is our ultimate guide to fermentors, including our eight top conical fermentors and a fermentor buying guide.

What’s A Conical Fermentor?

Just as the name suggests, conical fermentors are essentially fermentation vessels that are shaped like a cone. 

They have a valve at the bottom of the cone which catches all the solids and yeast that fall to the bottom during fermentation. 

This little tub can be removed. This will remove any risk of oxidation or infection, which makes a conical fermentor ideal for all homebrewing projects.

Benefits Of Conical Fermentors

Besides from there being no risk of breakage similar to a glass carboy, conical fermentors come with a number of great advantages.

Here is a list of some of the benefits of conical fermentors in comparison to flat-bottomed fermentors and other fermentation vessels.

No Need For Transfers

One of the biggest advantages with a conical fermentor is that you do not need to transfer your beer to a secondary fermentor.

All you have to do is open the bottom valve and remove any of the yeast or other sediments that have dropped to the bottom out of suspension.

This means that you also won’t run the risk of accidentally adding any air or bacteria into the beer. 

As all the sediments fall out and you can remove them regularly, your beer will also become clearer, which also prevents any sediments inside your bottle of keg when you transfer the final brewing result.

Easier Transfers

Talking of your final beer! Thanks to the valve at the bottom of the conical fermentor, you can easily transfer your beer from the fermentor into bottles or kegs.

This means that you won’t need to siphon the beer anymore, and there is going to be a lot less mess.

Most conical fermentors also have a racking arm that rotates, so you can move away from the yeast sediments which allows you to transfer a clear beer into your bottle or keg.

Easier To Clean

The majority of conical fermentors are made of good-quality plastic or stainless steel. This allows you to clean the fermentor much easier than a soft plastic bucket.

Additionally, conical fermentors have been specifically designed for the brewing process, so they have a large opening at the top and an easy-to-clean valve at the bottom which can be removed for thorough cleaning.

Collect Yeast Easily

Another great advantage of the bottom valve on a conical fermentor is that you can easily harvest any good yeast that has dropped out of suspension during the fermentation process.

You can use this yeast for future brewing processes, saving you time and money buying more yeast.

Also look out for any fermentors that a yeast container attached to the bottom. This collects the yeast and makes harvesting an unused yeast a great add-on.

The Top 8 Conical Fermentors For Homebrewing

Canonical fermentors may be a step up from the cheap plastic bucket or glass carboy, but for the best homebrewing results, you also need the right equipment.

We put together a summary of the best eight conical fermentors that we found useful for homebrewing.

Buying Guide

Undoubtedly, fermentation is the most important process when brewing beer, cider or other alcoholic beverages.

Although most homebrewing beginners try to use what they may have already available, it is worth looking at some special homebrewing equipment to ensure the results are what you want.

Conical fermentors come in a range of different sizes, designs and budgets, but they all will make your fermentation process when brewing beer much easier.

We put together a handy guide on what you should look out for when buying your first conical fermentor.

The 8 Best Conical Fermentors For Homebrewing

Choose The Right Fermentor Size

One of the first things to consider when you are looking for a conical fermentor is the size. You need to ask yourself how large is your batch going to be? 

The majority of beer recipes start with around 5 gallons, although they typically yield up to 6.5 gallons.

You need to allow for roughly 1.5 gallons of extra space because your batch will produce additional air bubbles.

If you are looking to make a standard batch, then we recommend going with a 6.5 gallon fermentor to allow enough space without having to buy a blow-off tube.

The majority of small fermentors are suitable for 2.5 gallons to 6.5 gallons, but it is best to check the manufacturer description.

Find The Right Material

Another important thing to look out for when buying a conical fermentation tank is the material the unit is made of.

Plastic can scratch very easily, and scratches are a breeding ground for bacteria that you don’t want in your beer.

Saying this, some plastic fermentors are excellent, but it is best to ensure that you buy a hard plastic fermentation tank that is more resilient to scratches.

However, the best material for a durable fermentor is stainless steel. It is very easy to clean, and it also lasts for much longer.

As stainless steel fermentation tanks are usually more expensive, they may be a better option for everyone who already tried making a few homebrewing batches with a plastic fermentor.

Easy Cleaning

This goes hand in hand with the material. Any type of plastic fermentor is more difficult to keep clean because the plastic surface will wear off after some time.

In comparison, a stainless steel surface is much more resilient to scratches. Some stainless steel fermentors can even be put into the dishwasher.

In addition, you also need to look out for how easy it is to unscrew any parts. You should also be able to lift off the lid and wipe the inside.

Especially smaller parts, such as the bottom dump valve, can get dirty very quickly, so you will need to clean this part after each batch.

Available Accessories

It is also worthwhile looking out for any available accessories that you can buy with your conical fermentor.

Some fermentors do not come with all the standard features but the manufacturer may offer them as accessories or upgrades. 

This is typically the case with thermowells or thermometers that allow you to monitor and control the temperature of your batch.

Accessories, such as leg extensions, casters and control thermometers can be very useful during the homebrewing process.

If you want to brew spirits or beer with a higher ABV, you may need to look for a fermentor that offers a pressurized option. 

Some premium fermentors allow you to upgrade to a working pressure of up to 15 PSI.


You can spend as much or as little money as possible for a fermentor but it is important to remember that the low budget units will also offer fewer essential features.

Final Thoughts

So, are conical fermentors really worth it? We tried and tested the above eight fermentors, and we found that they all do a very good job.

It takes some trial and error to find what works for you and how many different features you need for your homebrewing.
