Types of Brewery Fermentation Tanks

Stainless Steel Fermentation Tanks

Stainless steel fermentation tanks are the most popular choice for craft breweries due to their durability and versatility. These tanks are made from high-quality stainless steel and can withstand the pressure and temperature changes that occur during the fermentation process. They are also resistant to corrosion and easy to clean, making them a hygienic option for breweries.

One of the benefits of using stainless steel fermentation tanks is that they can be used for both primary and secondary fermentation. Primary fermentation is the initial stage of fermentation where the majority of the fermentation takes place, while secondary fermentation is a secondary stage of fermentation that helps to clarify and stabilize the beer. Stainless steel tanks can also be equipped with temperature control systems, which allow breweries to precisely control the temperature of the fermentation process.

Conical Fermentation Tanks

Conical fermentation tanks, also known as cylindroconical tanks, are a popular choice among craft breweries due to their unique design. These tanks are shaped like a cone and have a sloped bottom that allows for easy separation of the spent grain and hops from the finished beer. The cone shape also allows for the collection of yeast at the bottom of the tank, which can be harvested and reused for future batches.

One of the benefits of using conical fermentation tanks is that they allow breweries to conduct both primary and secondary fermentation in the same vessel, saving time and space. They are also easier to clean due to their sloped design and can be equipped with temperature control systems, like stainless steel tanks.

Wood Fermentation Tanks

Wood fermentation tanks, also known as foeders, are a more traditional choice for craft breweries and are often used to produce sour and wild ales. These tanks are made from oak or other types of wood and are known for imparting a unique character to the beer due to the tannins and other compounds found in the wood.

One of the benefits of using wood fermentation tanks is that they can be used for long-term aging of beer, allowing the flavors to develop and mature over time. They are also a visually appealing option for breweries, adding a rustic and authentic touch to the brewing process. However, wood fermentation tanks do require more maintenance and care than stainless steel tanks and are prone to contamination if not properly cleaned and sterilized.

Plastic Fermentation Tanks

Plastic fermentation tanks, also known as carboys, are a budget-friendly option for craft breweries and are often used for small-scale or experimental batches. These tanks are made from a food-grade plastic, such as PET or HDPE, and are lightweight and easy to transport.

One of the benefits of using plastic fermentation tanks is that they are inexpensive compared to other options and can be replaced easily if they become damaged. They are also easy to clean and can be equipped with airlocks to allow for the release of gases during fermentation. However, plastic fermentation tanks are not as durable as stainless steel or wood tanks and are not suitable for long-term aging of beer.

Ceramic Fermentation Tanks

Ceramic fermentation tanks, also known as amphoras, are a more traditional choice for craft breweries and are often used to produce ancient and exotic styles of beer. These tanks are made from ceramic and are known for their ability to retain heat, which can be useful during the fermentation process.

One of the benefits of using ceramic fermentation tanks is that they are porous, which allows the beer to breathe and absorb oxygen during fermentation. This can help to develop complex flavors and aromas in the finished product. Ceramic fermentation tanks are also visually appealing and can add a unique touch to a brewery’s branding. However, they are fragile and prone to breaking, and their porous nature also makes them more susceptible to contamination if not properly cleaned and sterilized.

Concrete Fermentation Tanks

Concrete fermentation tanks are a more recent addition to the craft brewing scene and are often used to produce modern and experimental styles of beer. These tanks are made from concrete and are known for their ability to retain heat and insulation properties, which can be useful during the fermentation process.

One of the benefits of using concrete fermentation tanks is that they are extremely durable and can withstand the pressure and temperature changes that occur during fermentation. They are also resistant to corrosion and easy to clean, making them a hygienic option for breweries. However, concrete fermentation tanks are expensive to manufacture and install, and they require specialized equipment and expertise to handle.
