When it comes to brewing craft beer, the choice of fermenter volume and quantity plays a crucial role in optimizing production efficiency. In this article, we will delve into the considerations for determining the volume of fermenters and the precise number needed for a brewery, taking into account factors such as beer variety, market demand, and fermentation cycles.
One crucial aspect of beer production efficiency is the careful selection of fermenters, determining both their volume and quantity. In this guide, we will explore the intricate considerations behind choosing the right fermenter size and number, offering valuable insights to enhance production efficiency and streamline operations in the dynamic world of craft beer brewing. Whether you're a seasoned brewmaster or now want to invest in a brewery, understanding fermenter selection is key to achieving a perfect blend of quality and productivity.
Choosing the Right Fermenter Volume:
The volume of a fermenter is closely tied to the brewhouse's capacity and the batch size. For example, a 50-hectoliter brewhouse producing four batches per day can be paired with fermenter volumes of 50, 100, 150, or 200 hectoliters. To make an informed choice, consider the types of beer brewed and the production scale.
Streamlining Production of Fewer Beer Types:
If your brewery focuses on a limited range of beer types, such as 2 to 3 mainstream products, opting for a larger fermenter volume, preferably 200 hectoliters, can be economical. This choice reduces investment costs, minimizes floor space requirements, and lowers labor intensity and cleaning costs during the pouring and filling process.
Diverse Craft Beer Portfolio:
For breweries catering to diverse markets like bars, craft beer experience halls, or engaging in OEM processing, where craft beer styles vary widely, a combination of fermenter volumes is advisable. This flexibility helps meet market demand efficiently, accommodating varying beer categories with different circulation speeds.
Determining the Number of Fermenters:
Understanding the fermentation process and cycles for different craft beers is key to optimizing brewery operations.
Example: Ale and Lager Beer Production:
If the fermentation cycle for ale beer is 2 weeks and lager is 4 weeks, the total storage capacity needed can be calculated based on daily wort production. For instance, brewing 200 hectoliters of wort per day requires at least 14 fermenters of 200 hectoliters for wheat beer. The total storage capacity is determined by multiplying the daily volume by the fermentation cycle. Similar calculations apply to lager beers.
Strategic Fermenter Configuration:
Consider a scenario where a brewery produces both ale beer and lager. For a brewery producing equal amounts of wheat and lager beers, a strategic fermenter configuration might involve 7 units for 200 hectoliters of wheat beer and 14 units for lager beers, totaling 21 units. Dividing the fermentation capacity into phases can also reduce investment risks.
Of course, when the actual design scheme is designed, the fermentation capacity can be divided into two or even three phases, which can reduce the investment risk.
By carefully considering the volume and number of fermenters based on beer variety, market demand, and fermentation cycles, breweries can optimize their production processes, reduce costs, and enhance overall efficiency in the craft beer brewing industry.
