Our History
Founded in 1973 by Phillip J. Sass during a global mustard shortage, Wisconsin Spice, Inc. began operations in an abandoned 19th-century feed mill and has since become a leading global force in the mustard industry. From its early focus on milling ground mustard and mustard flour for the sausage industry, the company expanded in 1975 to produce prepared mustard, directly competing with renowned international brands. In 1985, it relocated to a modern 130,000 sq. ft. state-of-the-art facility, becoming one of the few manufacturers capable of producing both dry-milled and prepared mustard under one roof while serving industrial ingredients, foodservice, and retail channels.
Under second-generation leadership, Wisconsin Spice continued its growth with the 2018 opening of the Phillip J. Sass Technical Center for research, development, and corporate functions, followed by the 2021 acquisition of its largest Canadian supplier, Besco Grain, Ltd., achieving greater vertical integration and operational efficiency. Today, the company is the world’s largest mustard seed miller, processing over 40 million pounds annually and supplying mustard products to more than 35 countries, with ongoing investments aimed at expanding capacity and delivering added value to customers worldwide.
