Oberweis Dairy

American corporation

Oberweis Dairy, headquartered in North Aurora, Illinois, is the parent company of several dairy related and fast food restaurant operations in the midwest region of the United States. Its businesses include a home delivery service available in parts of Illinois, Indiana, Missouri, Michigan, North Carolina, Texas, and Wisconsin, which delivers traditional dairy products, including milk, ice cream, cheese, and yogurt, as well as bacon and seasonal products. The businesses also include a chain of corporate owned "Dairy and Ice Cream Stores", in the Chicago area, which expanded the "Dairy and Ice Cream Stores" into Wisconsin, Indiana, Missouri, and Michigan after 2004. In 2012, Oberweis also began a new franchise of high end, fast food hamburger restaurants named "That Burger Joint". The firm is privately owned by the Oberweis family.

In 1915, Peter J. Oberweis began selling his excess milk to his neighbors in Kane County, Illinois; the business became full time in 1927. According to the Dairy's website, the family's farm was off of Molitor Road, in Aurora, Illinois. The family used a horse and milk float to deliver milk to their neighbors, beginning in 1927, after Peter J. Oberweis invested in half of the business of the Big Woods Dairy. During the Great Depression, Peter's son Joe dropped out of high school to help run the business. The business continued in the family, with Joe running the business through the 1950s. Current owner, Jim Oberweis, purchased the company from his brother in 1986 and named his son, Joe, CEO in 2007. In October 2022, Oberweis Dairy purchased milk from cooperatives instead of directly from family farm patrons.

In 1927, the company's founder began a home delivery service, which has continued since that time. Delivery has been in glass bottles, in the same way milk was delivered throughout the United States in the 1960s. A modern smartphone app supports tracking and timing deliveries.

In 1951, the Dairy and Ice Cream Stores began operation. The company currently has locations, both corporate owned and franchised, throughout Chicago, its suburbs, northwest Indiana, around St. Louis, Missouri, near Indianapolis, Indiana, Milwaukee, Wisconsin, and near Detroit, Michigan. Some projects for the retail stores were done on a trial basis at the company's corporate office in North Aurora (which also includes a retail store) before being put into place at other locations, such as the stores' drive through service, and the lunch/sandwich program, which began in 2004 and ended in July 2006. In 2012, Oberweis said that each dairy store generates between $1.25 million and $1.75 million per year.

In 2012, Oberweis opened their first quick service hamburger restaurant, named That Burger Joint, intended to expand as a chain and compete directly with Five Guys.

In 2017, Oberweis Dairy acquired Woodgrain Neapolitan Pizzeria, a pizzeria serving custom made personal pizzas in minutes.

Oberweis Dairy does not use or sell milk from cows treated with rBGH, recombinant Bovine Growth Hormone, despite United States Food and Drug Administration statements that the hormone does not have any detrimental effects on humans. Dairy cow diets contain corn and corn silage. Soy meal is used as a protein source. Haylage (chopped hay) and baled (dry) hay are also provided as feed. Vitamins and minerals are added to balance their diets. 90% of dairy herds graze when weather permits.
