Conical fermenters are a popular choice for home brewers who want to take their beer-making to the next level.

Buying Guide

When looking for the best conical fermenter for home brewing, there are several factors to consider.

There are numerous relevant aspects to consider when buying a conical fermenter.

Here are some key features to look at when choosing a conical fermenter:


The size of the fermenter is an important consideration. It should be large enough to accommodate the batch size of beer you plan to brew. A larger fermenter can also be useful if you plan to brew larger batches in the future. However, a smaller fermenter may be more manageable for a beginner or someone with limited space.


Conical fermenters can be made from a variety of materials, including stainless steel, plastic, and glass. Stainless steel is the most common material and is durable and easy to clean. Plastic fermenters are lightweight and less expensive, but may not be as durable as stainless steel. Glass fermenters are fragile but allow you to see the fermentation process.


There are several features to look for in a conical fermenter. Some models include a temperature control system, which can be useful for maintaining a consistent temperature during fermentation. Others include a spigot for easy transfer of the beer to secondary fermentation or bottling. Some fermenters also include a pressure relief valve, which can prevent explosions during fermentation.


Conical fermenters can range in price from less than $100 to several hundred dollars. Consider your budget and the features you need when choosing a fermenter. It’s important to remember that a higher price does not always guarantee a better product.


Consider the ease of cleaning and maintenance when choosing a fermenter. Stainless steel and plastic fermenters are generally easy to clean, but glass fermenters may require more care. Look for a fermenter with removable parts for easy cleaning.

In summary, when choosing a conical fermenter for home brewing, consider the size, material, features, price, and maintenance requirements. By taking these factors into account, you can find the best fermenter for your brewing needs.

More About Conical Fermenters

It’s always great to chat about the tools and tricks that make our brewing experiences better. Today, I’m diving deep into the world of conical fermenters.

Are conical fermenters really that beneficial for home brewing? The answer is, absolutely, they offer several advantages over traditional fermentation vessels. However, they’re not without their cons.

Andy P. – professional brewer

From my experience, shifting to a conical fermenter took my home brewing to the next level, but let’s start at the beginning.

Traditionally, home brewers, including myself, started off with bucket fermenters or carboys. Then, along came the conical fermenter. Resembling a cone, these fermenters are wide at the top and taper down to a point at the bottom.

The design isn’t just for aesthetics. The shape allows yeast and sediment to settle at the bottom, making the racking process smoother. They were primarily used in professional breweries before trickling down to homebrew setups.

History: The Evolution of the Fermenter

Centuries ago, fermentation was done in open vessels, which, thinking back, seems wild to us modern brewers. But as time went on and technology improved, brewing shifted from open vats to closed systems.

The conical fermenter itself was a design brought from the commercial brewing world. They became popular due to their efficiency and space-saving benefits. It’s fascinating to see how far we’ve come, and it’s a testament to the continuous evolution of brewing.

Pros of Conical Fermenters

  1. Efficiency: The most prominent advantage is its efficient design. The cone-shaped bottom ensures yeast and sediments collect away from the beer or cider, reducing the need to transfer between vessels.
  2. Harvesting Yeast: This is a biggie. With a conical fermenter, you can harvest yeast for reuse, saving you money and allowing consistency in batches.
  3. Reduction in Oxidation: Less transferring means less exposure to oxygen. This is vital as oxygen can spoil your brew.
  4. Easy Sampling: It’s a breeze to take samples without disturbing the sediment.
  5. Durability: Many conical fermenters are made from stainless steel, making them durable and easy to clean.

Cons of Conical Fermenters

  1. Cost: They are typically more expensive than traditional fermenters. Investing in one means you’re in it for the long haul.
  2. Size: They can be bulky. While they’re space-efficient inside, you need to have ample space in your brewing area.
  3. Maintenance: While easy to clean, the many parts can be a hassle to maintain.

Diving into my journey, I’ve brewed both cider and beer with conical fermenters. I remember my first batch of apple cider; the clarity was impeccable, something I struggled with when using traditional carboys. As for beer, the ease of dry hopping and yeast harvesting has been revolutionary.

The initial investment was hefty, but the consistent quality of my brews and the convenience factor made it well worth it.

In the grand tapestry of home brewing, conical fermenters have woven themselves a significant place. They provide efficiency, ease, and precision that traditional fermenters might lack. But, as with anything, they come with challenges.

The decision rests on your brewing goals, budget, and space.

To wrap up, here are 9 facts about conical fermenters:

  1. Derived from professional brewing.
  2. They allow for efficient yeast harvesting.
  3. Oxidation is reduced due to less transferring.
  4. They’ve been around since the mid-20th century.
  5. They can be used for both beer and cider brewing.
  6. The conical shape ensures better clarity in the final product.
  7. They come in varying sizes to suit different batch volumes.
  8. Some advanced models have temperature control features.
  9. They’re a testament to brewing evolution, reflecting our thirst for better brewing techniques.


1. What is the ideal size for a homebrewing conical fermenter?

The ideal size largely depends on the batch volume you generally produce. For most home brewers brewing 5-gallon batches, a 6 or 7-gallon conical fermenter is sufficient and for smaller test batches 2-3 gallons are fine. It’s always a good idea to have a little extra space to account for foam during fermentation.

2. Can I control fermentation temperatures with a conical fermenter?

Absolutely. Some high-end conical fermenters come with built-in temperature control systems. For others, you can immerse them in a temperature-controlled water bath or use external temperature control wraps to maintain the desired fermentation temperature.

3. How do I clean and sanitize a conical fermenter?

Cleaning a conical fermenter is similar to other brewing equipment. First, rinse out any residue. Then, use a brewing-specific cleanser, ensuring all parts are cleaned. Finally, thoroughly rinse and use a no-rinse sanitizer. The stainless steel models are particularly easy to sanitize due to their non-porous nature.

4. Are plastic conical fermenters any good?

Yes! They tend to be more affordable than stainless steel ones. Plastic fermenters are more sturdy, cheaper and lightweight, which is why we recommend them for home brewers. While they can work well for fermentation, be cautious of potential scratches inside, as these can harbor bacteria and contaminate your brews.

5. Can I use conical fermenters for secondary fermentation or lagering?

Certainly! The design of conical fermenters makes them excellent for secondary fermentation or lagering. The ability to remove sediment without transferring the brew is particularly advantageous during these stages.
