As a DIY homebrewer, you already know that the quality of the beer you brew, and the efficiency at which you do it, should be high on your
list of importance.

One of the ways you can eliminate a few steps during the brewing process, and save some time along the way, is to upgrade to a conical fermenter.

Primary and secondary fermentation can be done in just one conical fermenter, and can take the place of multiple traditional plastic buckets and carboys.

A conical fermenter can make your brew day run smoother because you are bypassing steps, using less equipment, cleaning and sanitizing less, and most of all, less chance of infecting your beer during the fermentation process if you usually use a secondary fermenter.

Ss Brewtech Brew Bucket Brewmaster Edition

This 7-gallon Chronical Fermenter from Ss Brewtech became one of the first quality stainless steel conical fermenters on the market, and has many features that make it a top choice for many homebrewers.

Besides being made from 304 stainless steel, which is lighter than glass and more durable than plastic, it has many features that will help with the beer brewing process.

It has a LCD thermometer which makes it easy to keep an eye on the fermentation temperature, a rotatable racking arm, welded carrying handles, large clamps to secure the lid, adjustable flow spigot, and four strong legs with rubber bottoms that won’t scratch your table or countertop.

Whether this is a big issue with you are not, there is one feature that is lacking on this model compared to some other conical fermenters.  You are not able to remove the trub and yeast during fermentation.


  • Made of high-quality 304 stainless steel
  • Stackable
  • LCD temperature gauge
  • Internal rotating racking arm


  • More expensive than other models
  • Cannot collect and remove trub during fermentation

FermZilla Conical Fermenter 7.1 Gallon/27 Liter

The FermZilla conical fermenter from Kegland has a new designed conical unitank, and an overhauled and improved version of their original Fermtasaurus model.

The FermZilla has a clear conical tank, made from durable clear PET, and is great for making 5 gallons of beer. It has many of the same advantages of similar stainless steel conical fermenters, but at a much cheaper price.

One special feature of the FermZilla is the ability to ferment and do closed transfers under pressure, which cannot be done with other plastic fermenters.

It comes with a sturdy reinforced stand, a 3-piece airlock, a 1000ml yeast and trub collection jar, and an adhesive thermometer to monitor temperature control.

The FermZilla will allow you to ferment, carbonate, and serve your beer from this one vessel.  If you do plan on doing pressure fermentation, you will need to purchase the pressure kit separately.


  • Ferment, carbonate, and serve from one vessel
  • Costs less than stainless steel
  • Large opening makes the tank easy to clean
  • Can see the fermentation taking place


  • Pressure kit not included
  • Threads are plastic and can strip

Craft a Brew Catalyst Fermentation System

This Catalyst Fermentation System from Craft a Brew is easy to understand and assembly can be completed in minutes. Both elegant as well as functional, this conical fermenter can be on display rather than hidden in a closet or garage.

It has integrated professional brewing features into a more compact device that is practical for most home brewing systems.

The multi-function conical design tank is made from Tritan®, a medical-grade and food safe BPA free polymer that has the clarity of glass, but all the durability of plastic.

The tank will hold 6.5 gallons of beer, and is designed to protect your beer from oxygen. It is also more scratch resistant than other plastic fermenters, and is completely dishwasher safe.

The large opening on the bottom acts as a trub trap and adapts to different size mason jars to efficiently collect sediment and yeast, with a dump valve at the bottom.  Anytime during fermentation, the butterfly dump valve can be closed off and the trub and yeast can be removed without disturbing the beer.


  • Lightweight but durable
  • Easy to collect yeast
  • Simple to use
  • Easy to clean


  • Not easy to move around

BrewDemon Conical Fermenter

Claiming to be the “worlds first” fermenting system for small batch home brewing.

This  BrewDemon conical fermenter is a budget friendly fermenter created for the home brewer who is not interested or ready for large batch brewing.

It is made from BPA-free professional grade, durable food grade PVC that won’t leave any unwanted off-flavors in your finished beer.

Although it is specifically designed to be used with all BrewDemon 2-gallon recipes, it will also work with 2 or 2.5 gallons of any beer, wine, kombucha, or mead recipe.

It has a wide mouth opening which makes adding ingredients and cleanup easy. Because it has a unique venting design that allows CO2 to escape while keeping oxygen and contaminants out, an airlock is not necessary.

Maybe not the most accurate, but it has a stick-on thermometer to monitor the fermentation temperature. Just remember that even though the plastic tank allows you to see what is going on inside, you still want to keep it out of the light and direct sunlight.


  • Versatile: Can make beer, wine, mead, or Kombucha
  • Great for making small batches
  • Compact design
  • No air-lock is needed


  • Cannot remove trub during fermentation – Not equipped with a butterfly valve
  • Sediment can collect above the spigot
  • Using Star-San is not recommended

7.9-Gallon FastFerment Conical Fermenter

If you are looking to move away from your standard plastic bucket or glass carboy, this food grade 7.9-gallon plastic conical fermenter from FastFerment is a budget friendly option, and will handle a 5 gallon batch of beer, wine, or cider.

The top has a wide opening which makes adding ingredients to your beer or wine a simple task. If you want to save your yeast and reuse it on another brew day, it also has a collection ball with a butterfly ball valve at the bottom of the cone that will catch the trub and harvesting yeast, which can also make for a much clearer beer or wine.

It also comes with a bottling filling attachment which allows you to easily rack your beer to a keg or the bottles of your choice.

These are definitely not deal breakers, but most accessories are not included in the box.  It does come with brackets for wall mounting, but that might not be practical for most homebrewers.

The items that are optional and not included in the box is a table/countertop stand, carrying straps, insulated jacket, and thermometer.


  • Wall mount design
  • Less expensive than other fermenter
  • Easy to clean


  • Plastic can scratch

It is an efficient time saver as racking is not needed, and can brew a 1 or 2-1/2 gallon batch of beer with ease. It also comes with a butterfly dump valve, and 4 ounce mason jar trub trap attachment for harvesting your own yeast, which can also save you more money in the long run.

What Is A Conical Fermenter?

A conical fermenter is a single container used in the beer fermentation process, and can be made from glass, plastic, or stainless steel.  If you’ve seen pictures or visited a large commercial brewery, or even a local micro-brewery, I’m sure you have seen a conical fermenter. 

These are the massive shiny large tanks that have a cone or conical shape at the bottom of the vessel.  The cone-shaped bottom allows for solids to collect and has a dump valve for a simple and sanitary removal of yeast and sediments, anytime during fermentation.

Depending on the type of beer you are brewing or just a personal brewing preference, many homebrewers choose to do a two-stage or secondary fermentation.  Normally this would mean a higher risk of contamination and oxidation when transferring the beer from a primary to a secondary, and then again to a bottling bucket.

 With a conical fermenter as part of your brewing equipment, all of these steps can take place in one tank.

What Are The Advantages & Benefits Of A Conical Fermenter?

Previously, a quality conical fermenter was almost out of the question for an amateur home brewer because of the outrageous cost.

But over the last several years as the homebrewing hobby continues to skyrocket, this once out of reach type of equipment has become more affordable and can now be bought on just about any budget.

There are quite a few advantages for the commercial brewer as well as a novice homebrewer when brewing with a conical fermenter.

One Fermentaion Vessel

When brewing beer at home, most people often use a plastic bucket or glass carboy for “primary fermentation”, then transfer to another optional “secondary” vessel to add additional ingredients and separate the beer from the layer of yeast and sediment.

But when using a conical, you can essentially do the same thing by removing the trub from the tank and leave the beer behind where it can age in the same vessel.

Reusing The Yeast

After the yeast has finished its job, it doesn’t die, it just becomes dormant. Another advantage of a conical fermenter is you can remove the yeast from the tank and reuse it on future brews, and save you money.

In fact, many commercial brewers will use the same yeast up to 6 times before it is thrown out.

Check out our “How To Make a Yeast Starter” page if you are interested in making your own yeast starter the next time you brew.

Saying Goodbye To Racking

Many homebrewers will do a transfer two or three times during brew day.  Once from the primary to the secondary fermenter, from secondary fermenter to the bottling bucket, and then from the bottling bucket to filling the bottles or keg.

Every time you transfer from one vessel to another, you are introducing oxygen to the beer, which is a risk for infection and oxidation.  Using a single conical fermenter allows you to complete all the steps from one vessel.

Saves Brewing Steps & Time

Of course this goes without saying, but anytime you can eliminate specific steps in the brewing process, you can drastically cut down on your preparation and overall brewing time.

Less Brewing Equipment Means Less Cleaning & Sanitizing

Because you are using less equipment overall, you will save time by not needing to clean and sanitize unnecessary and extra equipment like a secondary fermenter when using a conical style ferementer.

Many units are made of stainless steel which makes cleaning much easier, and even the plastic models are easier to clean because they have a wide opening on top.

Even though a conical fermenter will be more expensive than a bucket or carboy, you will be able to eliminate these two items along with some racking and bottling equipment as well.

Things To Think About Before Buying

When it comes to picking the right conical fermenter, there are a few things you should consider to choosing the right product for your overall brewing needs.

It is important that the one you end up choosing works with all the variables to your home brewing environment: space, budget, amount of beer you want to make.

Extra Accessories

Often times there are “optional” accessories that are included when you buy a specific product, like a trub trap for yeast collection, or a thermometer for temperature control.

Many times the low-budget models come with the bare minimum and that’s it, where some of the higher priced models already come equipped with all the bells and whistles.

Just be aware that you might be spending more money in the long run, every time you have to buy an optional piece that is not already included in the price.

Physical and Volume Size

Conical fermenters come in a variety of sizes, so you want one that will fit into your brewing space, for sure. If you do the majority of brewing in your basement, almost any size will do, but if you are a kitchen brewer who has to share space with a significant other, your options will be somewhat limited.

Make sure you have a good idea how much space you have available for the brewing and storage, and that will help determine the perfect size.

For the volume size, if you buy a model where you can only make 2 or 3-gallon batch sizes of beer, you are severely limited on future brews if you want to make the larger batch sizes.

But just because you buy a bigger one that can hold 5 or 6 gallons of beer, that doesn’t mean that it will be able to work for small batch beer brewing.

What It's Made Of And The Quality Of The Parts

Once you have a size in mind that you think will work in your brewing space, deciding on the material of the fermenter is next.  Do you want a plastic or stainless steel conical fermenter?

Of course the ones made of Polyethylene Terephthalate (PET) will be less expensive and not as heavy, but it can scratch and provide a place for bacteria to hide.

A stainless steel conical fermenter looks professional, is easy to clean, much larger & heavier, more durable, and quite a bit more expensive, but can last a lifetime if taken care of.

It is important to purchase a fermenter that is built solid and sturdy, and parts like the spigot, yeast collection ball, butterfly valve, etc, are made of quality materials and can be taken apart or removed easily when it is time to clean and sanitize for the next brewing day

The Price

Of course conical fermenters vary in volume size, construction, and accessories, but the price is usually the deciding factor when choosing a particular model.

Basic vessels for small-batch brewing made from plastic are a much more cost effective than the larger stainless steel conical models, but there are limitations.  It is always wise to buy the one you can afford, but not to limit yourself going forward for future brewing.

But, whether you are looking to spend less than a hundred bucks, or willing to spend a thousand, there is an option that can cater to just about every budget.

What Are The Drawbacks To Using A Conical Fermenter?

If you are thinking about buying a conical fermenter to take your home brewing to the next level, there are not a lot of drawbacks or disadvantages to using one, besides the larger physical size and the increased cost.

These “uni-tanks” are larger than a plastic primary fermenting bucket or glass carboy and will usually require more space in your brewing area.

Keep in mind that conical fermenters are more expensive than your standard vessel, so if you are not sure about how often you want to brew or if you are experimenting with brewing for the first time you may not want to invest in this product just yet.

Also, a conical fermenter, particularly if it stainless steel, can be heavy and difficult to transport. If you are starting your brewing process in one place and moving to another, you need to take into account how to safely handle the weight and protect it so no damage occurs, to you or your beer.

Final Say

So what is the best conical fermenter?

When purchasing any piece of beer brewing equipment, you should never spend more than you can comfortably afford, but it also isn’t wise to buy the least expensive product too.

The overall features of the SS Brewtech Brew Bucket stainless steel chronical fermenter is why this one comes out on top, and is also a favorite among many other amateur home brewers and professional brewers as well.

This fermentation system has that true beer brewing experience feel, it’s easy to clean, and should last a lifetime if taken care of, and one of the best conical fermenters you can buy.

Happy Brewing!
