Stadium Authentic Mustard is the trademarked name of a brown mustard, manufactured in Illinois, popular in Northeast Ohio, particularly in Cleveland. Stadium Authentic is an alternative formulation of Joe Bertman's original signature mustard recipe, also produced by Bertman's family's company as Bertman Original Ballpark Mustard. Stadium Authentic Mustard is sold at retail outlets and served in over 150 stadiums and arenas throughout the United States.
In 1969, David Dwoskin, a sales representative of Bertman's company in the northeast Ohio area, formed the Davis Food Company to make "The Brown Mustard" served at the Cleveland Municipal Stadium available for retail sales in supermarkets. In 1971, David Foods registered the name "The Authentic Stadium Mustard". In 1982, Davis Food Company obtained exclusive rights to sell to both wholesale and retail markets as well as stadiums, arenas and other venues. In the early 1980s there was a disagreement between Bertman and Dwoskin. Dwoskin produced the original mustard under the Stadium Mustard brand through his own company. The Bertman Family continues to sell its version of the mustard through its Bertman Foods Company.
Dwoskin told Cleveland.com that his mustard is served in 150 stadiums in the United States including First Energy Stadium and Rocket Mortgage FieldHouse "www.stadiummustard.com/". www.stadiummustard.com/. Archived from the original on 2011-07-16. Retrieved 2011-06-02.</ref>
Both mustards are sold in grocery stores, specialty food shops, and online. A 2011 blind tasting revealed strong similarities between the two brands, with Bertman, which has some sugar in it, being a bit sweeter, and Stadium being a bit more spicy.
Stadium Mustard is made with a brown seed, has no preservatives, sugar, fat or fillers. It is a mildly spicy brown mustard more similar to European mustards than American deli-style brown mustards. Stadium Mustard is unique in that it is homogeneously brown in color, compared to traditional coarse-ground brown deli mustards, which are typically mottled in appearance and may feature both yellow and brown mustard seeds.
