Bright Tanks – The Future of Fermentation

What are Bright Tanks?

Bright tanks are specialized vessels used in the brewing industry for the secondary fermentation of beer. These tanks are typically made of stainless steel and are designed to hold the beer after primary fermentation is complete. During this secondary fermentation stage, the beer undergoes a natural carbonation process as yeast consumes any remaining sugars in the beer.

How do Bright Tanks work?

After primary fermentation is complete, the beer is transferred to the bright tank, where it is stored at a controlled temperature and pressure. As the beer sits in the tank, yeast consumes the remaining sugars in the beer, producing carbon dioxide as a byproduct. This carbon dioxide dissolves into the beer, creating the bubbles that give beer its characteristic fizziness.

Bright tanks are also equipped with special valves that allow brewers to control the pressure and carbonation levels in the beer. By adjusting these variables, brewers can create beers with different levels of carbonation, from flat and still to highly carbonated and effervescent.

Advantages of using Bright Tanks

Bright tanks offer several advantages over other fermentation methods. First and foremost, they allow brewers to control the carbonation levels of their beer more precisely. This means that brewers can create beers with consistent levels of carbonation from batch to batch, ensuring a high-quality product every time.

In addition, bright tanks are more efficient than other fermentation methods. Because the beer is stored in a sealed vessel, the carbon dioxide produced during secondary fermentation is captured and used to carbonate the beer naturally. This eliminates the need for additional carbonation equipment and reduces the amount of carbon dioxide that is released into the atmosphere.

Bright tanks also offer better clarity and stability than other fermentation methods. Because the beer is stored in a sealed vessel, it is protected from outside contaminants and remains free from sediment and other particles. This results in a clearer, more stable beer that can be stored for longer periods of time.

Applications of Bright Tanks

Bright tanks are used primarily in the brewing industry, but they can also be used in other fermentation processes. For example, they are sometimes used in the production of wine and cider, where they can be used to clarify the product and control its carbonation levels.

Bright Tanks vs. Other Fermentation Methods

Bright tanks offer several advantages over other fermentation methods, such as open fermentation and bottle conditioning. Open fermentation, which involves fermenting the beer in an open vessel, can lead to contamination and inconsistent carbonation levels. Bottle conditioning, which involves adding additional yeast and sugar to the beer before bottling, can be time-consuming and can result in inconsistent carbonation levels.

In contrast, bright tanks offer a controlled, efficient, and precise way to carbonate beer. By controlling the pressure and temperature in the tank, brewers can create beers with consistent carbonation levels and a stable, clear appearance.

Choosing the Right Bright Tank

When choosing a bright tank, brewers should consider several factors, including the size and capacity of the tank, the materials used to construct the tank, and the type of valves and controls available.

Size and capacity are important considerations, as they will determine how much beer can be stored and carbonated in the tank at one time. Materials are also important, as stainless steel tanks are more durable and easier to clean than other materials.

Finally, brewers should consider the valves and controls available on the bright tank. These can include pressure relief valves, pressure gauges, and carbonation stones, which can be used to control the pressure and carbonation levels in the tank.


Bright tanks are an essential tool in the brewing industry, offering a controlled and efficient way to carbonate beer.
