AB Mauri® North America dates back to the introduction of Fleischmann’s® Yeast in the U.S. in 1868, thanks to the industry-changing vision held by brothers Charles and Maximillian Fleischmann who partnered with Cincinnati businessman James Gaff. Eight years later, Fleischmann’s® Yeast made the move north of the border to Canada.

By the early 20th century, the company merged with several other food corporations, including a merger forming Standard Brands by J.P. Morgan in 1929. Coincidentally, this was also the same year that the company began sponsoring the musical variety radio program, The Fleischmann’s Yeast Hour, starring Rudy Vallee.

Following several acquisitions later – including by Nabisco Brands, Inc., in 1981, and Australian company Burns, Philp & Co., Ltd., in 1986 – Associated British Foods purchased Burn’s Philp global yeast and bakery ingredients companies including the Fleischmann’s® Yeast assets, and AB Mauri was formed in 2004 to service the commercial baker. A sister company – ACH Food Companies, based in Chicago – directs the Fleischmann’s® Yeast consumer retail business in North America.

In 2005, AB Mauri purchased Innovative Cereal Systems, LLC, located in Wilsonville, Oregon. Today, what started as the Gaff, Fleischmann & Co. nearly 150 years ago has now evolved to AB Mauri® North America, a division of AB Mauri.
