French_Roll_Production_02_webAlpha Baking Company, Inc. was established in 1979 with the acquisition of the Mary Ann Baking Company in Chicago. Founded in 1935, Mary Ann is best known for the ever-popular Chicago style poppy seed hot dog bun. In 1981, Alpha Baking purchased S. Rosen’s Baking Company, a Chicago staple and baker of Jewish hearth rye breads and variety rolls since 1909. Through the years, Alpha Baking has continued to grow with the acquisition of Kreamo Bakers in La Porte, Indiana in 1979, National Baking Company in Chicago, Illinois in 1997, Natural Ovens Bakery in Manitowoc, Wisconsin in 2007, and recently in 2016 with the addition of a new sweet good facility in Chicago, and a new baking facility in Grand Rapids, MI.

Alpha Baking offers direct store delivery (DSD) service in central and southern Wisconsin, northern Illinois, and northwestern Indiana. In addition to national grocery chains and independent grocery stores, we also service national restaurant chains, quick service restaurants, schools, institutions, major league sports franchises, warehouse club stores…the list is endless. In fact, over 90% of Chicago-area hot dog stands use our Mary Ann poppy seed hot dog buns!

Alpha Baking Company, Inc. has a long history of donating product, money, and time to local charities, including food banks across the Midwest.

Perhaps our most visible donation was the promotion Alpha Baking Company, Inc. ran for its S. Rosen’s brand’s 100 year anniversary. For one week that summer, each fresh S. Rosen’s hot dog bun sold generated a ten cent donation to five food banks serving Illinois, Indiana, and Wisconsin. This highly successful promotion resulted in a lump sum donation of over $120,000 to help feed the Midwest’s hungry.

In addition to monetary donations, Alpha Baking Company, Inc. regularly donates bread product to local food banks, resulting in thousands of pounds of bread donations per year. Donations are also made to events and community organizations that arise through our connection to our community.
