Innovation in food distribution changed everyone in the food business, including Cains. In 1970, direct delivery to grocery warehouses instead of store-door delivery revolutionized manufacturing and shipping methods. Bigger volume was now possible, and Cains moved to a spacious new facility in Ayer, Massachusetts in 1973.
This new home made it possible for Cains to focus on its core business of mayonnaise and a new line of salad dressings. As the company's potential grew, Cains was sold to BolsWessanen in 1986. Sister companies were Heluva Good Cheese and Kemps Frozen Yogurt.
John E. Cain Co. became Cains Foods, and under its new owners, the product line expanded for both retail and food service customers. Most importantly, the company never lost sight of its overall goal to manufacture foods of the highest quality and reliability, and never lost its name: CAINS!
