Koops' Mustard

Koops' Mustard is a historic American brand founded by Peter Koops in 1897. Originally established with a focus on simple, high-quality recipes using traditional stone-grinding methods, the brand has remained a prominent name in the condiment industry for over 125 years. The manufacturing process centers around its primary facility in Wisconsin, where mustard seeds sourced from both the United States and Canada are processed into a variety of flavors, including Dijon, Horseradish, and Stone Ground varieties.

Today, the brand is owned and operated by Olds Products Company, a family-owned enterprise headquartered in Pleasant Prairie, Wisconsin. Olds Products Company has maintained the brand's commitment to clean-label ingredients and traditional production techniques. Despite its long history, the company remains privately held, focusing on long-term growth and regional production within the American Midwest rather than under the umbrella of a global conglomerate.
