In the craft beer industry, the choice of brewing equipment is crucial to beer quality, production efficiency, and cost control. For small breweries, home brewers, or craft beer enthusiasts, the three-vessel brewing System is a common and efficient choice. Micet Group engineers will introduce the construction, advantages, and application scenarios of the three-vessel brewing system in detail and illustrate its application in craft beer production by giving examples.
What is a 3-vessel beer brewing system?
The 3-vessel brewing system is a set of professional-grade equipment consisting of three components: a mash tun, a lauter tun, and a boiling pot. Each container has a specific purpose, ensuring optimal control of the brewing process. The system allows for simultaneous operation, which means you can mash, lauter, and boil simultaneously without waiting for one step to complete before starting the next. It is a favorite of brewers who want to improve batch consistency and shorten brewing time.
The main features of the three-vessel brewing system
- Efficiency: Simultaneous processes reduce overall brewing time.
- Scalability: Suitable for small to large operations.
- Control: Independent vessels allow for precise temperature and process management.
- Customization: Accommodates a variety of brewing styles and batch sizes.
Advantages of 3-vessel brewing system
- Improved brewing efficiency: Since the 3-vessel system allows multiple steps to be performed simultaneously (such as heating water, mashing, and boiling at the same time), waiting time is reduced and batch capacity is increased. For example, when the mash tun is mashing, the hot water barrel can simultaneously prepare the hot water required for the next batch, thereby reducing the waiting time of the entire brewing process.
- More accurate temperature control: The mashing process requires precise temperature control to ensure maximum enzyme activity. The 3-container system allows for more stable temperature management. For example, water of different temperatures can be prepared in the HLT for the gradually heated mashing process, improving mashing efficiency and wort quality.
- Improved wort quality: Since the 3-container system provides a clearer filtration process, the wort has a higher degree of clarity, reducing the amount of spent grain residue entering the boiling process, and improving the taste and flavor of the final beer.
- Strong scalability and suitability for scale-up: For small breweries or craft beer enthusiasts who want to expand their production capacity, the 3-container system provides a more flexible production capacity. It can be upgraded with larger capacity equipment to accommodate larger batches without affecting brewing quality.
- Suitable for a variety of beer styles: The 3-container system supports a variety of mashmethods (such as single-step mash, step mash, and German three-step mash), which can adapt to the production of various styles of beer such as lager, ale, stout, etc.
The brewing process of a 3-vessel brewing system
- Heating brewing water: First, heat the water in the hot water barrel to 70-78°C in preparation for mashand rinsing malt.
- Mash Tun: Add the crushed malt to the mashbarrel and mix it with hot water, keeping it between 60-70°C, so that the enzymes can convert starch into fermentable sugars. This step usually lasts 60-90 minutes.
- Lauter Tun: After mash, the wort is transferred to the lauter tun to separate the spent grains, while the residual sugars are rinsed with hot water to increase the extraction rate.
- Boiling and adding hops: The filtered wort is transferred to the boiling barrel and heated to 100°C for boiling (60-90 minutes), and hops are added at different time points to give bitterness and aroma.
- Wort Chilling: After boiling, use a chiller to quickly cool the wort to 18-25°C (depending on the yeast type) for fermentation.
- Fermentation: The cooled wort is transferred to a fermentation tank, yeast is added, and primary fermentation is carried out for 1-2 weeks. After that, secondary fermentation or maturation may be required depending on the beer style.
- Packaging: After fermentation is complete, the beer is filtered, carbonated, and bottled or kegs before drinking. This 3-container system is efficient and controllable, suitable for home craft brewing and small commercial brewing.
What features does a three-vessel brewing system have?
맥아 즙 통
- Starch conversion: The wort tub is where the ground grains come into contact with hot water. This interaction activates enzymes in the malt, converting the grains’ starches into fermentable sugars. This sweet liquid is called wort and is the basis of beer.
- Temperature Grading: Some brewing recipes call for different temperatures to activate different enzymes at different stages of mashing. Modern mash tuns are equipped with advanced temperature controls to enable multi-step mashing.

- Wort-to-grain separation: After the mashing is complete, the wort needs to be separated from the grain bed. The lauter tun has slotted plates at the bottom that allow the liquid wort to pass through while retaining the solid grain bed.
- Flushing: This is the process of flushing the grain bed with hot water to extract any remaining sugars. The lauter tun facilitates flushing by evenly distributing the hot water over the grain bed.

- Boiling and adding hops: The collected wort is boiled in a boil kettle. Hops are added at different stages of the boiling process to add bitterness, flavor, and aroma to the beer.
- Sterilization: Boiling wort has another key function: sterilization. The boiling process kills any harmful microorganisms, ensuring a clean subsequent fermentation process.
- Vortex formation: Some boiling pots have a vortex function, where the liquid circulates to form a vortex. This helps to settle solid particles in the center, making it easier to extract clear wort from the sides.

How to build a 3-vessel beer brewing system?
Selecting equipment
The first step in building a 3-vessel beer brewing system is to choose the right equipment. The system consists of three main parts: the mash tun, lauter tun, and boiler kettle, and the hot liquor tank (HLT) is used to heat and store hot water. The mash tun is responsible for converting the starch in the malt into sugar, the lauter tun is used to separate the spent grains and wort, the boiler is used to boil the wort and add hops, and the hot liquor tank provides the required hot water for mashing and rinsing.
System layout
In terms of layout, the placement of the 3 vessels can usually be arranged in a straight line or a stepped arrangement. The straight line arrangement is suitable for limited space, while the stepped arrangement uses gravity to flow the wort, which helps improve efficiency. The pipes in the system should ensure a smooth flow of wort from the mash tun to the lauter tun and then to the boiler. Make sure the distance between each vessel is appropriate for easy operation and maintenance.
설치
When installing the equipment, you first need to assemble the hot water tank (HLT), make sure the heating element or gas stove is firmly installed, and connect the temperature probe to ensure that the water temperature is controllable. Then, the drainage system of the mash tun and lauter tun needs to be connected to the pipes through valves to ensure smooth flow of wort. The heating system of the boil tun should ensure that the wort can be heated to boiling in the required time. All equipment must be installed according to the operating manual and ensure that the pipes must be connected correctly to avoid leaks or other problems.

All equipment must be installed according to the operating manual and ensure that the pipes must be connected correctly to avoid leaks or other problems.
Pipe connection
All containers need to be connected through pumps and pipe systems. The hot water tank (HLT) delivers hot water to the mash tun for mashing and rinsing malt. After the mashing process, the mash tun delivers the wort to the lauter tun through the pump, and the lauter tun delivers the clarified wort to the boil tun through the drain valve. During the boiling process, hops are added to the wort, and finally, the cooling system quickly cools the wort and prepares it for fermentation.
Testing and debugging
After installation, the system needs to be tested and debugged. Check that all pipes, valves and heating systems are working properly to ensure smooth flow of wort and accurate temperature control. Conduct a small-scale trial brew to check whether each step is operating smoothly, whether there are leaks, temperature fluctuations or unstable flow rates. If problems are found, they should be adjusted and repaired in time to ensure that the system can operate normally.
