The Guide to Brewery Fermentation Tanks
Overview of Brewery Fermentation Tanks
Fermentation tanks are a cornerstone of the beer brewing process, transforming wort into beer through the magical process of fermentation. They come in various shapes, sizes, and materials, each tailored to specific brewing needs. Whether you’re a homebrewer or running a commercial brewery, understanding the nuances of fermentation tanks can greatly impact your brewing success. This guide delves into everything you need to know about brewery fermentation tanks, from equipment types and brewing processes to suppliers, prices, and maintenance tips.
The Role of Fermentation Tanks in Brewing
Fermentation tanks are where the wort, a sweet liquid derived from malted grains, is transformed into beer by yeast. This process not only produces alcohol but also contributes to the beer’s flavor, aroma, and carbonation. Tanks can be as simple as a glass carboy for homebrewing or as complex as a conical stainless steel tank for commercial breweries.
Types of Fermentation Tanks
Fermentation tanks come in several types, each serving different brewing scales and purposes:
- Glass Carboys: Ideal for small-batch homebrewing.
- Plastic Fermenters: Affordable and lightweight, suitable for beginners.
- Stainless Steel Conical Tanks: Used in commercial brewing for their durability and ease of cleaning.
- Unitanks: These versatile tanks can ferment and carbonate beer in the same vessel.
| Type | Description | Usage |
|---|---|---|
| Glass Carboys | Transparent, easy to clean, but fragile. | Homebrewing |
| Plastic Fermenters | Lightweight, less expensive, but prone to scratches and staining. | Beginners |
| Stainless Steel Conicals | Durable, easy to clean, resistant to contamination, and often used in commercial setups. | Commercial brewing |
| Unitanks | Multifunctional, allowing fermentation and carbonation in one tank, often found in advanced setups. | Advanced home and commercial brewing |
The Brewing Process Using Fermentation Tanks
Brewing beer is an art that requires precision and patience. Here’s a step-by-step overview of how fermentation tanks are used in the brewing process:
1. Preparation and Wort Production
The brewing process begins with mashing malted grains to extract fermentable sugars. The resulting liquid, known as wort, is boiled and hops are added for bitterness and aroma.
2. Transferring to the Fermentation Tank
Once the wort is cooled, it’s transferred to the fermentation tank. Yeast is then pitched into the wort to begin the fermentation process. This is where the magic happens – yeast consumes the sugars and produces alcohol and carbon dioxide.
3. Fermentation Phase
The primary fermentation typically lasts between one to two weeks, depending on the beer style and yeast strain. During this time, the temperature and environment are carefully controlled to ensure optimal yeast activity.
4. Conditioning and Maturation
After primary fermentation, the beer may undergo a secondary fermentation or conditioning phase. This step enhances the flavor and clarity of the beer. Some brewers transfer the beer to another vessel, while others keep it in the same tank (especially if using unitanks).
5. Carbonation and Packaging
Finally, the beer is carbonated if necessary, either naturally (in the bottle) or forced (in kegs or tanks). The finished beer is then packaged in bottles, cans, or kegs for distribution.
Capacity, Space, Design, and Customization of Fermentation Tanks
When choosing fermentation tanks, it’s essential to consider their capacity, space requirements, design features, and customization options.
| Factor | Details |
|---|---|
| Capacity | Tanks range from 1 gallon for homebrewers to 500 barrels or more for large breweries. Consider your batch size and production needs. |
| Space Requirements | Ensure you have adequate space for the tanks, including height clearance for conical tanks and space for ancillary equipment. |
| Design Features | Look for features like cooling jackets, sampling ports, and pressure relief valves. These can enhance control over the fermentation process. |
| Customization | Many manufacturers offer custom-built tanks to suit specific brewing processes and facility constraints. Consider future expansion when planning your setup. |

Installation, Operation, and Maintenance of Fermentation Tanks
Proper installation, operation, and maintenance of fermentation tanks are critical to ensure longevity and optimal performance.
| Aspect | Details |
|---|---|
| Installation | Involves setting up the tank, connecting to necessary utilities (water, power), and ensuring proper insulation and cooling systems are in place. Professional installation is recommended. |
| Operation | Follow manufacturer guidelines for filling, fermenting, and emptying tanks. Monitor temperature and pressure closely. |
| Maintenance | Regular cleaning and sanitization are vital. Inspect tanks for signs of wear or contamination. Replace seals and gaskets as needed to maintain a tight seal. |
How to Choose the Right Supplier for Brewery Fermentation Tanks
Choosing the right supplier involves more than just comparing prices. Here are key factors to consider:

FAQs
Q: What size fermentation tank do I need for homebrewing?
A: For homebrewing, fermentation tanks typically range from 1 to 10 gallons. The size depends on your batch size. A 5-gallon tank is common for standard homebrew batches.
Q: Can I use plastic fermentation tanks for commercial brewing?
A: While plastic tanks are suitable for small-scale or home brewing, commercial breweries prefer stainless steel tanks for their durability, ease of cleaning, and contamination resistance.
Q: How do I clean and sanitize my fermentation tank?
A: Clean with a non-abrasive cleaner and sanitize using a suitable sanitizer. Regular cleaning prevents contamination and ensures consistent beer quality.
Q: What is a unitank and how does it differ from standard fermentation tanks?
A: A unitank is a versatile vessel that allows both fermentation and carbonation in the same tank, saving space and reducing transfer needs. Standard tanks typically require separate vessels for these processes.
Q: How much do commercial fermentation tanks cost?
A: Prices vary widely based on size and features. Small commercial tanks may start around $1,000, while large, custom-built tanks can cost upwards of $100,000.
Q: What materials are fermentation tanks made from?
