Lime Rock Springs Co. is the corporate name and the company was founded in 1916 in Dubuque, Iowa by John C. Gantz. The name was derived from the natural springs on which the bottling facility was originally constructed. The Company bottled a full line of flavored soft drinks under its own label until 1936 when Pepsi-Cola was added. The Company has ceased producing at the Dubuque location and now sources its products from Wis-Pak, Inc. which is a multi-plant production cooperative servicing the Company and thirty-one other independent Pepsi-Cola Bottlers within the Midwest.

Lime Rock Springs Co. is the local distributor of Pepsi, Diet Pepsi, Mt Dew, and other PepsiCo brand soft drinks as well as Lipton teas, Aquafina waters, Klarbrunn still and sparkling waters, Gatorade, Rockstar energy drinks, Starbucks bottled beverages, etc. The company operates out of one warehouse located in Dubuque, Iowa servicing an area which includes Clayton, Dubuque, and Jackson counties in Iowa, JoDaviess county in Illinois, and Grant, Lafayette, and a portion of Iowa county in Wisconsin. The company employs approximately 70 people and has a delivery and service fleet of roughly thirty vehicles.

The Company is independently owned and operated, and is the exclusive franchisee of PepsiCo within its area of operations. It has been operated by the Gantz family for four generations. Both the Company and the Gantz family have a strong sense of community and family members serve on the boards of various civic and charitable organizations in the community.
