Why are fermenters conical?

Fermenters are essential equipment in the production of various types of fermented products, including beer, wine, and yogurt. They come in different shapes and sizes, but one of the most popular designs is the conical fermenter. This article will explain why fermenters are conical and the advantages of using this type of fermenter.

What is a Conical Fermenter?

A conical fermenter is a specialized vessel used for the fermentation of beer, wine, and other fermented products. It is a cylindrical container that tapers to a conical bottom. The conical shape allows for the collection of sediment or trub at the bottom of the tank during fermentation, which makes it easier to remove and discard later.

Why are Fermenters Conical?

  1. Improved Yeast Collection

Conical fermenters are designed with a cone-shaped bottom that allows for the collection of yeast at the end of the fermentation process. Yeast is an essential component in the production of beer, wine, and other fermented products. It is responsible for converting the sugar in the wort or juice into alcohol and carbon dioxide. Conical fermenters allow for the yeast to collect at the bottom of the tank, making it easier to collect, harvest, and reuse in future fermentations.

  1. More Efficient Fermentation

Conical fermenters have a smaller surface area compared to other fermenter shapes, which makes them more efficient in terms of heat transfer. This means that they can maintain a consistent temperature throughout the fermentation process, which is crucial for producing high-quality fermented products. Additionally, the conical shape promotes a more even distribution of yeast and other microorganisms throughout the fermenter, leading to a more efficient fermentation process.

  1. Easy to Clean

The conical shape of fermenters makes them easy to clean. The sediment or trub that collects at the bottom of the tank during fermentation can be easily removed by draining it out of the bottom of the tank. This eliminates the need for complicated cleaning processes that may be required for other fermenter shapes.

  1. Space-Saving

Conical fermenters are designed to be stacked on top of each other, which makes them space-saving. This is particularly useful for breweries and wineries that have limited space. Additionally, conical fermenters can be placed on wheels, making them easy to move around and store when not in use.

Types of Conical Fermenters

  1. Stainless Steel Fermenters

Stainless steel fermenters are popular in commercial breweries and wineries due to their durability and ease of cleaning. They are resistant to corrosion and can withstand high pressures, making them ideal for high-volume fermentations.

  1. Plastic Fermenters

Plastic fermenters are affordable and lightweight, making them ideal for homebrewers and small-scale fermentations. They are also easy to clean and sanitize, and some models come with built-in spigots for easy transfer of the fermented product.

  1. Glass Fermenters

Glass fermenters are transparent, which allows for easy monitoring of the fermentation process. They are also non-reactive, which means that they do not affect the taste or quality of the fermented product. However, they are fragile and require careful handling to prevent breakage.


Conical fermenters are an excellent choice for producing high-quality fermented products due to their efficient design and ease of use. They allow for improved yeast collection, more efficient fermentation, easy cleaning, and space-saving. Additionally, they come in different types, including stainless steel, plastic, and glass, making them suitable for different types of fermentations.
