The Ultimate
Brewing Solution
Efficiency, taste, and cleanliness – these are the keywords regarding this ultimate brewing solution. ULTROM is revolutionising the brewing process. A horizontal mixing drum, in combination with Ultrasound, enables new possibilities. Homogeneous stirring, a faster hydrolysis and a better and unique taste of the beer are only a few of the benefits of this new technology.

Proof
Ultrasonic cavitation breaks down the starch in the malt without damaging the grain. The enzymes gain more surface to work on and demonstrably convert it faster and more completely. Degassing the medium also improves the yield. With homogeneous stirring and mixing the malt in the mash, cavitation is evenly distributed. Low resistance in the stirring process allows the process to be stopped and started at any time. This so called “rewash” becomes very useful when a vacuum or compact mash hinders the lauter process or any technical issue forces stirring to stop. This particular feature provides the possibility to rewash the malt at any time and thus gain higher yield out of the malt.
Efficiency
With over 95%* brewhouse efficiency, ULTROM revolutionises brewing. The drum is fully insulated and heats the medium from all sides: fast heating, an even, stable temperature and high energy efficiency. As mashing and lautering take place in ULTROM, no solids need to be pumped – only the wort goes to the kettle. While it boils, the next brew can already start in ULTROM. This saves time and energy. Mashing in is easier too: no lumps form in ULTROM, so the malt can be added faster and hassle-free.
* US calculation, based on the maximum obtainable extract. Using the common German calculation (based on the grist, of which approx. 80% is hydrolysable), this corresponds to over 76%.
Compactness
This ultrasound barrel requires no headspace and is thus 35% more compact than normal two or three vessel brewhouses. Furthermore, as the vessel is closed, no ventilation system is required. The ULTROM is closed, coated, and filled to the top, hence it is more economical than any other brewing system.
Flavour
Ultrasound degasses brewing water and mash, lowering the dissolved oxygen. Together with the closed drum, filled to the brim, this means less oxidation during mashing. Oxygen-dependent enzymes are slowed down: lipoxygenase, which leads to staling flavours, and ascorbate oxidase (AAO), which breaks down ascorbic acid. This better preserves the malt’s natural antioxidants. The result: a fresher taste, better flavour stability and aroma that is preserved in the mash – particularly valuable for alcohol-free beers. Because of the covered round shape of the ULTROM and its comparatively small open valves at the top, if CO2 must be added it would not escape easily.
Quality
This Swiss patented brewhouse stands for quality and reliability. Ultrasound technology of its finest from Weber Ultrasonics AG (Karlsbad near Karlsruhe, Germany) is known as state of the art and appreciated by customers all around the world. The device is built to last thanks to the specialized welding. ULTROM is available as an addition to existing breweries or as a complete brewhouse.
Clean
When the ultrasound is switched on, cavitation cleans ULTROM by itself. No shovelling of spent grains is needed: they slide out easily at the end of the drum into a container.
