J. Hans van Leeuwen

Johannes van Leeuwen, professor at Iowa State University in the department of civil, construction and environmental engineering, has succeeded in developing the purest vodka in the world. Van Leeuwen said the vodka is fully produced in Iowa with Iowa corn and by Iowa entrepreneurs. IngeniOz — a combination of “ingenious” and “ozone” — has established an unmatched standard for vodka.

Van Leeuwen, originally born in Gouda, Netherlands, lived in South Africa and Australia before moving to the United States in 2000. He developed an interest in distillation from his brother, who made moonshine with a distillation kit when they lived in South Africa, where making moonshine is legal.
