Choosing the right number of fermentation tanks is an important part of brewery planning. The number of beer fermentation tanks depends on your brewhouse capacity, production volume, fermentation time, beer styles, and future expansion plans.

For a small craft brewery, a few stainless steel fermenters may be enough. A commercial brewery with higher production usually needs more brewery fermentation tanks to maintain a continuous brewing schedule.

一、How to Calculate the Number of Fermentation Tanks

A simple way to estimate your required fermentation capacity is:

Required Fermentation Capacity = Weekly Production × Average Tank Occupancy Time

For example, if a brewery produces 5,000 liters of beer per week and beer occupies the fermentation tanks for approximately two weeks, the brewery needs around 10,000 liters of fermentation capacity.

This capacity could be provided by:

• 5 × 2,000 L fermentation tanks
• 4 × 2,500 L fermentation tanks
• Or another combination based on the brewery's production plan

The actual configuration should also consider tank working volume, cleaning time, beer styles, and future production growth.

二、What Size Fermentation Tanks Does a Brewery Need?

Fermentation tank size is usually selected according to the brewhouse system and production schedule.

For example:

• 10 HL brewery: 1,000–2,000 L fermenters may be suitable
• 20 HL brewery: 2,000–4,000 L fermenters may be suitable
• 50 HL brewery: larger commercial fermentation tanks are typically required

Breweries producing different beer styles may choose several tank sizes to improve production flexibility.

三、Fermentation Tanks, Unitanks and Brite Tanks

A stainless steel fermentation tank, also known as a conical fermenter, is mainly used for beer fermentation and yeast collection.

A unitank can combine fermentation, conditioning, and carbonation in one pressure-rated vessel. This can be useful for breweries that want a more flexible brewing system.

A bright beer tank (brite tank) is generally used for beer conditioning, carbonation, clarification, and storage before packaging or serving.

A typical beer production process may look like:

Brewhouse → Fermentation Tank → Bright Beer Tank → Packaging

四、Why Choose Stainless Steel Fermenters?

Stainless steel is widely used for commercial brewery equipment because it is durable, hygienic, corrosion-resistant, and easy to clean.

Modern conical fermentation tanks can also be equipped with cooling jackets, temperature sensors, pressure gauges, sanitary valves, CIP spray balls, and other accessories.

A properly designed glycol cooling system is also important for maintaining stable fermentation temperatures.

五、Choosing a Brewery Equipment Manufacturer

When purchasing fermentation tanks, breweries should consider more than tank capacity. Important factors include stainless steel quality, welding quality, cooling performance, pressure rating, CIP compatibility, customization options, and after-sales support.

An experienced brewery equipment manufacturer can also help match fermentation tanks with the brewhouse, glycol cooling system, CIP system, bright beer tanks, and packaging equipment.
