White Sonora wheat sourdough is a soft, sweet-flavored heritage-grain bread milled from the oldest wheat variety in the Americas, introduced by Father Kino in the 1690s.

Father Eusebio Francisco Kino introduced white Sonora wheat to the Pimeria Alta (modern Tucson region) in the late 1690s, the first wheat grown in the Americas. The variety nearly disappeared in the 20th century to commercial high-protein wheats, but Native Seeds/SEARCH preserved the heirloom seed line. Don Guerra of Barrio Bread won James Beard Outstanding Baker 2022 for his community-supported bakery that mills white Sonora wheat from Mission Garden plots and Pivot Produce growers into naturally-leavened loaves.
