Beer brewing

  • What are the basic components of a brewery?

  • A brewery can be divided into two parts: the brewhouse, where all the brewing is done, and the fermentation area, which consists of fermentation and maturation tanks. In order for the brewing process to run smoothly, you also need hot water and cold water tanks. Hot water is used to rinse the malt (lautering), while the cold water is needed for the process of wort cooling using a plate heat exchanger.

    The brewhouse consists of a mash mixer, a lauter tun, a kettle, and a centrifugal separation tank (whirlpool). The processes can be carried out in separate process tanks, or you can purchase a brewhouse with a smaller number of combined tanks, which are adapted so that different phases of the brewing process can be carried out in them.

  • How is the brewhouse installed and who can do it? What about the first use?

  • The brewhouse installation site must be prepared beforehand: you must arrange all necessary supply connections (water, steam, glycol, electricity). All work must be performed by properly qualified personnel and in accordance with the provided instructions.

    You can start brewhouse operation on your own or you can ask SK Škrlj to help you with it.

  • Is the system manual or automatic?

  • All systems are semi-automatic with individual automated functions. This means that the presence of an operator / brewer is essential. Process control is carried out using the main touch screen control panel. The control panel enables you to regulate the temperature inside the tanks, the mixer and pump speed, as well as to set the timers, the step mashing program, etc.

    All brewhouses except the MB series have manual valves. Only the step mashing program and heating to the desired temperature are automated, while the timers turn off individual functions, e.g. boiling or whirlpool.

  • Do I have to buy any additional equipment to be able to start brewing?

  • Each brewhouse system includes a process pump, a heat exchanger, and pipe connectors, and it is equipped with a touch screen control panel for process control and a complete electrical wiring system. Some models also include a hot water tank, while with others it has to be purchased separately. Beer fermentation and maturation tanks are also extremely important for the brewing process - you can order them according to your own needs or depending on the desired capacity of your brewery (more here).

    All brewhouses, with the exception of the standard BHM250 and BHM500, which are heated with oil, require a suitable steam generator for heating and a sufficient amount of water, which is used for the purposes of the brewing process (wort cooling). There is also some additional equipment that can be important for system operation: a malt mill, wort and beer transfer pipes, a mobile pump for liquid flow and equipment cleaning, a CIP station, a grist case, a malt conveyor, and a cooling unit for fermentation and maturation tank cooling.

  • What about hot water? Do I need an extra hot water tank?

  • A hot water tank may be part of the main brewhouse system or it has to be purchased separately, it depends on the model. You can see a detailed description of our different brewhouse systems here.

    We advise you to purchase a hot water tank with a volume that is at least twice the nominal volume of the brewhouse (the size of one batch). This way, the hot water will always be ready, even if you are preparing several batches in a row.

  • How are the water tanks controlled?

  • The water tanks that are part of the brewhouse system (established pipe and electrical connections, built-in pump) are controlled via the main control panel of the brewhouse. The control panel is equipped with a touch screen and its user interface is available in multiple languages.

    The user enters the desired temperature into the program and then presses the suitable button to activate water heating or cooling. The process is deactivated automatically when the desired water temperature is reached.

    The pump is also controlled using the main control panel - it enables you to activate/deactivate a tank's pump and to also set a pump cycle. In this case, the pump of the selected tank is activated automatically: it alternates between pumping and pause in accordance with set time parameters.

    The control panel also displays current water temperature and flow, as well as the total amount of water pumped.

  • Which heating medium is used?

  • Heating is carried out along the tank wall and on the bottom, where the heating medium flows through the double jacket and, consequently, increases the temperature inside the tank.

    The heating medium used in most of our brewhouse systems is steam. The standard models of our smaller systems (BHM250 and BHM500) use thermal oil, but steam heating is available as an alternative. If the brewhouse is heated with thermal oil, the basic system includes a heater, a pump, a manifold, and a control unit.

  • In what way and how fast is wort cooled? What is the cooling medium?

  • Wort cooling is carried out using a heat exchanger. The wort enters the plate heat exchanger at a temperature of approximately 100 °C. Due to the interaction between the hot wort and the cold cooling medium inside the heat exchanger, the wort temperature gradually decreases, while the temperature of the cooling medium increases.

    The brewhouse can be equipped with a single-stage or two-stage heat exchanger. If the brewhouse is equipped with a single-stage exchanger, the only cooling medium used is cold water, which is stored inside a water tank and used later on in the process. However, if there is a two-stage heat exchanger, both cold water and a water/glycol solution (cooling manifold) are used for cooling. Find out how to choose the right heat exchanger here.  The heat exchangers are dimensioned so that all the wort is cooled in 45 minutes (on average).

  • How many batches can be completed in one day?

  • The number of batches you can make in one day depends on brewhouse configuration and the recipe you use. With our brewhouses, you can complete 4 to 11 batches per day, as they are designed in such a way as to enable a simultaneous execution of multiple processes. This means that you can, for example, start mashing malt for a new batch before you've transferred the wort from the kettle to the fermenters (knockout). Consequently, if multiple processes are executed simultaneously, cycle time becomes significantly shorter.

    Another factor to always take into account is the total capacity of the fermenters and maturation tanks at your disposal. You can only make as much wort as you are able to store, as beer needs 3 to 4 weeks to mature (depending on the type).

  • How are the brewhouse and other tanks cleaned? Do I need a CIP station?

  • Quality beer requires perfect hygiene during each production process. The brewhouse and tanks must be thoroughly cleaned after each use. In order to prevent product contamination and an unwanted aftertaste, it is extremely important to thoroughly clean the inside of the tanks and pipe connections, as well as any other part of the system that may have come into contact with the product during the brewing process.

  • How to clean a brewery

  • The brewhouse and tanks must be thoroughly rinsed with water to wash away any larger dirt residue. The entire system is then cleaned with a cleaning solution, which is prepared in accordance with the manufacturer's instructions and pumped between the tanks using a pump and flexible pipes.

    Suitable cleaning and disinfection products, as well as other cleaning equipment for breweries are available in specialized shops. They must be suitable for use on surfaces that come into contact with food and beverages. After cleaning, the entire system must be thoroughly rinsed with clean water.

  • Cleaning and disinfection with CIP (Clean-In-Place) technology

  • The CIP station is not part of a brewery's mandatory equipment, but it is definitely recommended to have one. The CIP process is the most effective way to remove accumulated dirt and sediment from tanks, pipes, connectors, and other equipment that is connected to the system.

    The advantage of CIP cleaning is that it enables equipment cleaning and disinfection without system component disassembly.

  • Is regular service necessary? How are service and support arranged (in other countries), if there is a malfunction or if something needs to be repaired?

  • A user manual is available on our web page ( and it also includes product maintenance and cleaning instructions. Spare parts are available at SK Škrlj, they can be delivered in a few days.

    Regular servicing is not necessary. Our trained personnel are available for remote assistance if there is a malfunction, and, if necessary, can also pay you a visit and solve the problem.
