Optisteep has been developed by Water IQ in collaboration with the University of Berlin and Boortmalt. The technology increases the speed of moisture intake and improves the enzymatic modification of the barley kernel. In doing so, only a single wet steep process is needed while maintaining or even improving overall malt quality and yield. This results in a groundwater consumption reduction of 40% in the steeping process. In 2022, Boortmalt has installed Optisteep in 5 malting plants in the world.
