Tiswin is an alcoholic beverage brewed from corn. Tiswin is also the sacred saguaro wine of the Tohono O'odham, a group of aboriginal Americans who reside primarily in the Sonoran Desert of the southeastern Arizona and northwest Mexico.
The saguaro, the largest cactus in the world, is in many respects the sacred tree of the Tohono O'odham, who reside in the Sonoran Desert of southeastern Arizona and northwest Mexico. From the fruit of the saguaro they make a sacred fermentation called tiswin or sometimes nawai.
