The Ingenious Design of Conical Beer Fermenters: Unveiling the Secrets Behind Their Success

Conical fermenters are an integral part of the beer production process, and their design is crucial for ensuring successful fermentation. Many breweries use conical fermenters for various reasons. Here are some advantages of conical fermenters:

Advantages of Conical Fermenter

  • The conical fermenter is a “uni-tank” that allows primary fermentation and aging/storage to be done in the same vessel. Unlike flat-bottomed fermentation vessels, which require transferring the beer to a separate vessel for aging, a conical fermenter allows you to open the valve at the bottom, letting the sediment flow out while leaving the beer behind.
  • Another advantage is the ability to remove yeast and sediment from the beer at any point during the fermentation process. This makes it easy to reuse the yeast by pumping some out and washing it. Using one batch of yeast for multiple batches can save you money in the long run.
  • If your fermenter is higher than the bottling/barrel vessel, you can transfer the wort without using a siphon. Some closed-top fermenters even allow you to apply CO2 pressure to the top, forcing the beer to divert from the bottom.
  • Many conical fermenters are made of stainless steel, which makes them easy to clean and maintain. Even plastic cones can be cleaned in most cases.

Carbon Dioxide Removal

Conical fermenters are capable of removing carbon dioxide, a by-product of yeast metabolism during fermentation. If carbon dioxide is not removed from the tank, it can build up pressure and potentially cause an explosion. In a conical fermenter, the carbon dioxide rises to the top and is released through a valve, ensuring safe levels throughout the fermentation process.

Promotion of Alcohol Production

Conical fermenters ensure constant contact between yeast and wort. The yeast needs to be in contact with the wort to consume sugars and produce alcohol and carbon dioxide. By settling to the bottom of the storage tank, next to the wort, a conical fermenter facilitates this contact, allowing the yeast to work effectively during fermentation.

Conical Shape for Rapid Fermentation

The conical shape of the fermenter promotes fast and complete fermentation. The cone shape helps distribute the yeast evenly throughout the tank, resulting in more consistent fermentation. This even distribution ensures the integrity of the fermentation process and contributes to a beer with a consistent flavor and aroma.

Easier Cleaning and Disinfection

A conical fermenter is easy to clean and sanitize. Its shape allows solids and other sediment to settle at the bottom, simplifying draining and cleaning processes. This ease of cleaning is crucial for maintaining the quality of the beer, as it ensures the tank remains free from harmful contaminants.


In summary, conical fermenters are essential for the beer production process. Their unique design allows for easy yeast harvesting, efficient removal of carbon dioxide, continuous contact between yeast and wort, rapid and complete fermentation, and straightforward cleaning and sanitation procedures. Conical fermenters are widely used in breweries and play a key role in producing high-quality beer.
