Fermentation tanks

Are you looking for a conical tank for your brewery? A conical fermenter is one of the most popular utilitarian beer fermenters on the market. 

The fermentation tank is essential microbrewery equipment. Fermenters are an important part of every brewery, from the smallest home brewery setup to the largest commercial brewery enterprise. 

Although any receptacle could ostensibly be used as a fermentation vessel, the technology used to manufacture these vessels today is state of the art. You could say that a fermenter is where all the magic happens, where the great craft beer is born.

With this in mind, the fermentation tank should always be the object of key supervision and management, if you want the end result to be the production of high-quality beer. 

Fermentation Tank Essentials

Fermentation tanks are essential for beer production. They are where yeast converts sugars into alcohol and carbon dioxide, which gives beer its characteristic taste and texture. As such, the quality of fermentation tanks plays a significant role in the quality of beer produced. In this section, we will discuss the essential features of high-quality fermentation tanks, including the materials used, ease of use and maintenance, user experience, durability, size and setup, stability, and budget-friendliness.

High-Quality Materials and Craftsmanship

The materials used in fermentation tanks can significantly affect the quality of beer produced. Stainless steel is the most common material used in commercial fermentation tanks, thanks to its durability, corrosion resistance, and ease of cleaning. Other materials such as copper, plastic, and wood can also be used but are less common. Regardless of the material used, the quality of the materials and craftsmanship is crucial. High-quality materials and craftsmanship ensure that the fermentation tank is well-built and long-lasting, minimizing the risk of leaks or other issues that can affect beer quality.

Ease of Understanding, Operating, and Maintaining

Fermentation tanks should be designed to be easy to understand, operate, and maintain. This means that the tanks should have a simple design that is easy to comprehend, and the operation should be straightforward. Additionally, maintenance requirements should be minimal, and the tanks should be easy to clean. This makes it easier for brewers to focus on the brewing process, rather than worrying about technical issues or complicated procedures.

User Experience

User experience is a critical consideration when choosing fermentation tanks. The tanks should have features that enhance the user experience, such as easy-to-use valves and fittings, clear and visible level indicators, and adjustable legs or feet. These features make it easier for brewers to work with the tanks, resulting in a more efficient and productive brewing process.

Durability and Longevity

Durability and longevity are essential features of high-quality fermentation tanks. They should be built to last and withstand the harsh conditions of brewing. A durable fermentation tank can provide years of reliable service and minimize the risk of leaks or other issues that can affect beer quality. Factors that affect the longevity of fermentation tanks include the materials used, the construction method, and the level of maintenance.

Proper Size and Setup

Choosing the right size and setup for fermentation tanks is crucial for efficient and effective beer production. Factors that determine the size of fermentation tanks include the volume of beer produced, the type of beer produced, and the brewing process used. The setup of the fermentation tanks should also be considered, including the location of the tanks, the layout of the brewery, and the necessary utilities such as water and electricity. Proper sizing and setup ensure that the fermentation process is optimized, resulting in higher-quality beer and increased production efficiency.


Stability is another essential feature of fermentation tanks. Stability ensures that the fermentation process is consistent, resulting in consistent beer quality. Factors that affect the stability of fermentation tanks include the design of the tanks, the materials used, and the environmental conditions. Stable fermentation tanks minimize the risk of contamination, which can result in off-flavors and aromas in the beer.


While high-quality fermentation tanks may come at a higher cost, there are options for budget-friendly tanks that still provide reliable service and quality beer production. Factors that affect the cost of fermentation tanks include the materials used, the size of the tanks, and the level of customization required. Careful consideration of these factors can help breweries find affordable options that meet their brewing needs without compromising on quality.

At the beginning of any brewery setup, the brewmaster or operations manager must focus on buying the best and most reliable cellar tanks. This is key to consistently long-term, high quality beer production. Even if you pay a little more for the unit you are buying, a solidly good fermentation tank produces tastier beer, which leads to more profit and a faster payoff. Cutting corners is never a good idea if you want to replicate your beer recipe accurately and reliably every time.

How to plan ahead the brewery fermentation tanks for your brewery?

We suggest that you always base your choice on what room space is available (length/height x width x breadth) on site at your chosen location.

Next: what beer output do you need for stable supply and sales? Do you have an expansion planned? What are your mid to long term beer production goals?


Choose the volume of the fermenter for beer according to the output of the Brewhouse. You can choose a fermenter based on single, double, or even multiple times the volume of the Brewhouse output. Of course, this depends on the total output efficiency  of the brewhouse. Conical fermentation is one of the most requested brewery equipment orders we are asked to custom produce for our valued clientele. 


Arranging each fermentation period according to the output plan. The work schedule of the tank, the cleaning cycle, if they work efficiently, etc. Operating efficiency is directly related to your profit turnover.


  • As your brewery business expands, you may find that the current number of existing fermentation tanks is not enough. If the space is already fully utilized, your best bet might be to build an additional cellar room. Each YoLong fermenter is manufactured to work on its own or with many other fermenters, according to the volume output you require.
  • YoLong fermenters can be bought with a few to future expansion; if more volume output is needed, we can help you plan how to make space for subsequent expansions of production capacity. 
  • If you want bigger output, you can choose the YoLong unitank, which acts in the capacity of a fermenter and BBT. This arrangement will free up space for you to fit in more fermenters. 
  • Before your YoLong fermentation tank is delivered, a drainage ditch must be designed.
  • For countries located in earthquake zones, New Zealand, Japan, etc. Every fermenter is shipped with bolt holes on the fermentation tank legs which can then be fixed in place. This must be requested in advance so that the bolt holes can be included in the design.

Large Fermentation Tanks

For large fermentation tanks, the production process, as well as the transportation and installation, are far more cumbersome than small size fermenters.

During the manufacturing process, large-scale fermentation tank production processes require specialist lifting tools.  This means that the manufacturing process is slower, because the workers have to add highest quality welding and other production parts.

The length of a single weld for a large-scale fermentation tank takes longer for our welding technicians to do. The work must show beautiful craftsmanship, as well as functionality and flawless finish.

Staying focused for a longer period ensures continuous consistency and quality of the welds: the hallmark of any YoLong conical fermenter. Additionally, controlled measures are taken to ensure there is no roughness or dent, because this is where germs can hide. Aesthetics and hygiene are important here at YoLong.

In the process of assembling the inner and outer cylinders, a vehicle-mounted crane is used during assembly. This requires the skill of the workers who operate the hoists and ground cooperating personnel are there to oversee.

This skilled and coordinated effort ensures the perfect combination of the inner and outer cylinders, with no friction and scratches, no matter how large the stainless fermenter size.

Large-scale fermentation tanks are more complicated to manufacture than small-scale fermentation tanks. They are generally set up outdoors, and that means the place where they are to be set up must be built in advance.

The ground must be level and able to bear the fermenter’s weight. This is why every large scale YoLong fermentation tank comes with special adjustable feet, which allows it to automatically adapt to minor ground irregularities, keeping the bulky fermenter perpendicular to the ground for stability.

A YoLong conical fermenter is designed to promote optimal beer fermentation. If you are looking for a conical fermenter for sale, please contact the YoLong team and we can suggest the best fermentation equipment to suit your budget and layout.
