Laboratory Mash Bath
The Mash Bath (Mashing Bath) is a professional automated instrument designed for brewery and malting laboratories. It is used for precise determination of malt extract using standardized EBC and ASBC analytical methods.
This device fully complies with the following EBC and ASBC standards:
- CONGRESS Method:
The CONGRESS method produces wort from which relative densities are determined and extract percentages are calculated. At the same time, the resulting congress wort is used to determine a number of other analytical malt parameters, such as saccharification, wort filtration/flow-off, color, clarity, viscosity, pH, soluble nitrogen compounds, etc. - HARTONG Methods (20, 45, 65, 80):
These methods are used to obtain worts whose extract values indicate extract yield at given temperatures. From the values of individual extracts, it is possible to determine the enzymatic activity developed during malting, assess the malt’s amylolytic potential, and evaluate its proteolytic and cytolytic modification. - ASBC Method:
The American standard for brewing analytics. - Custom Profiles:
Possibility of programming specific temperature ramps via PC.
Main benefits and applications:
- Full automation: The Mash Bath automatically controls temperature curves and the mashing process.
- Standardized methods: Supports the CONGRESS, HARTONG (20, 45, 65, 80), and ASBC methods.
- High accuracy and calibration capability: Ideal for laboratories operating under ISO 9001/9002 quality systems.
- Flexibility: Allows setting custom profiles using the PROFILE and THERMOSTAT methods.
- Decades of experience: We have been manufacturing Mash Baths for over 25 years, producing more than 600 units during that time. Our Mash Baths are used by major companies such as Heineken, Asahi, Anheuser-Busch, Cargill, and Soufflet, as well as by small breweries and maltings.

Frequently asked questions
What is the 1-CUBE Mash Bath used for?
It is used for laboratory processing of malt samples to determine their quality and extract yield according to international EBC and ASBC standards.
Can the device be connected to a computer?
Yes. Models labeled “Monitoring” include PC software and an interface (RS232/USB) for controlling the Mash Bath from a computer, allowing real-time monitoring of the set temperature profiles.
What is the capacity of the Mash Bath?
We manufacture models for 4, 8, or 12 stainless steel beakers with a volume of 500 ml each.
What is the difference between the Standard and Automatic versions?
The main difference lies in the level of automation for distilled water addition during the mashing process. While measurement methods run automatically on both versions, operator involvement differs:
- Standard version: Requires operator assistance. The device signals acoustically when it is necessary to manually add preheated distilled water to the beakers containing the mash, or to take a sample for the saccharification test. Distilled water is poured manually by the operator from test tubes placed in the Mash Bath, where it is preheated to the required temperature.
- Automatic version: Fully unattended in terms of distilled water addition. The device automatically dispenses preheated distilled water, eliminating the need for manual intervention during the method.
