Buying Guide

When it comes to conical fermenters, it’s important that you know which buying criteria to keep in mind when you shop to ensure you pick out the best product. This short but comprehensive buying guide will lay out everything you need to know about this product, and you can use it to narrow down your choice to the product that will help you be the most productive. You can also get this equipment with any home brewing starter kit.

Defining a Conical Fermenter

Fermentation is arguably one of the biggest parts of the brewing process because it’s where your ingredients turn into spirits. This is the stage where your beer develops the carbonation and alcohol content, and you’ll need a beer fermenter to make it happen. You’re spoiled for choice when it comes to your fermentation vessel, including kegs, carboys, plastic buckets, and fermenters.

A conical fermenter is precisely what it sounds like, and it has a cylindrical top on a cone-shaped bottom, and there is a valve located at the bottom point. These come made out of stainless steel or plastic for the most part, but you can get a number of different features like automatic temperature control, rotating racking arms, and built-in stands.

Biggest Buying Considerations

Although there are arguably dozens of buying considerations that come into this piece of brewery equipment, a few are more important than others. Keeping an eye on them as you compare products will help you make a smart choice when you start seriously shopping for your new stainless steel conical fermenter.


The quality of your fermenter is very important because it’ll dictate how long your item lasts, and you can usually choose from plastic or stainless steel. Plastic models are usually more cost-effective, but they won’t last as long as stainless steel as they’re prone to cracking or breaking down. If you scratch your plastic equipment, this tiny scratch creates the perfect space for bacteria to thrive and taint your beer.

Your fermenter’s construction and the brand are also important because more well-known brands dedicate themselves to using high-quality products that won’t leak or break down. A seamless construction will contribute to the quality by helping to reduce the chances of leaks, and this also makes it easier to clean.


Take a look at the features that your product has but keep in mind that many of them are relatively basic. Most of these products will need a hose when they finish the fermentation process because you’ll have to extract the liquid inside the device to leave the trub behind at the bottom of the cone shape for easy collection. Some products allow you to tap out the liquid that you can continue to use throughout the brewing process for an added convenience factor.

If you choose to buy this model over a model that requires a hose, you’ll get a more convenient and faster brewing process that doesn’t require any additional items because everything comes from a single product.

Ease of Cleaning

You want your new product to be very easy to clean thoroughly between batches because this can help prevent bacteria from growing and tainting your brew. Look for fermenters with a wider opening that you can easily fit your hand inside to reach every area, and you don’t want raised seams or crevices that are difficult to get in.

Most stainless steel conical fermenters come with a mirror finish throughout the inside of the tank that is very easy to clean with hot water and soap. Plastic ones come with wider openings and a simple design that makes them easy to both clean and dry.


While you don’t necessarily want to buy the cheapest stainless steel fermenter on the market, it’s important that you pay attention to the price and find a model that has a good balance of features and durability for the money.

You want to do your research to ensure you find the best conical fermenter on the market, and make sure to look at the materials, features it offers, and then compare it to the price. This will help you narrow down our reviews to find the product that offers you the most features for the price point, and it’ll help you find the one that is the easiest to clean and maintain.

Stand or Mounting Hardware

Your stand for your fermenter should be very broad and sturdy to hold the hardware and prevent it from spilling or tipping over when you use it. Metal is a very common stand material as it is very resistant to rust and corrosion, and it also stands up very well to wear and tear.

If you don’t have the space to set your fermenter on the floor, some models offer a wall-mount system that attaches to the studs in your wall to keep it out of your way. You will most likely pay more for this model since it also comes with a floor stand to allow you to swap out, but it can be well worth it.
