If summer isn’t complete without a dash of French’s Classic Yellow Mustard, you are in for a treat. This Saturday, August 1, in celebration of National Mustard Day, French’s introduces its Mustard Beer. Beer maker Oskar Blues partnered with French’s to develop French’s Mustard Beer- a semi-tart tropical wheat beer infused with an array of citrus fruits to complement French’s Classic Yellow Mustard. The beer will be available to order online while supplies last.
