Nowadays, the demand for craft beer is increasing, and the demand for corresponding brewery equipment is also rising. The number of fermenters to be configured in the entire production process is a core issue that determines production capacity, operational efficiency, and investment costs.
Many of our customers ask when purchasing brewery equipment:"My mashing system is 2000L/3000L/5000L. How many fermenters should I equip?"
Next, let's explain how to match fermenters:
Why must the number of fermenters be more than the mashing equipment? Because the beer fermentation time is several times that of mashing.
Mashing cycle: 6–10 hours/batch. Fermentation cycle: 7–30 days/batch.
If there are too few fermenters, the following problems will occur:
Mashing equipment shuts down and waits (wasted production capacity)
Inability to produce multiple types of beer at the same time
Limited room for new product development
Increased costs and decreased return on investment
Therefore, the number of fermenters must be at least 4–8 times that of the mashing system to ensure continuous production.
Industry standards: How many fermenters should be configured for different mashing capacities?
Based on the most common configurations in global craft breweries currently, we provide the following recommendations:
2000L mashing system: Recommended number of fermenters: 6–8 units of 2000L or 2–4 units of 4000L (double-capacity tanks)
Suitable for: Small and medium-sized craft breweries, restaurant breweries.
3000L mashing system: Recommended number of fermenters: 8 units of 3000L or a combination of 4 units of 3000L + 4 units of 6000L (double-capacity tank combination)
Suitable for: Regional brands, standardized beer production lines.
5000L mashing system: Recommended number of fermenters: 8–12 units of 5000L or a combination of 4–6 units of 5000L + 2–4 units of 10000L
Advantages: Flexible, low cost, can produce multiple styles of beer.
However, the following issues should also be considered:
When choosing fermenter capacity, the following factors need to be considered:
Market demand and main products
If your main product has high sales volume, it is recommended to add large tanks (double-capacity tanks).
Beer style
Lager (longer fermentation cycle) → requires more tanks
Ale (shorter cycle) → slightly fewer tanks can be used
Daily production capacity planning
Do you mash every day? How many batches do you produce per week?
Budget and site size
Double-capacity tanks can effectively reduce unit investment costs, but require more space.
The number of fermenters required for large-capacity brewery equipment is not fixed; it is calculated comprehensively based on mashing system capacity, beer style, production cycle, and market demand.
If needed, we provide customers with a one-stop solution from planning and design to equipment implementation.
