Barrio Bread is a small neighbourhood bakery on the east side of Tucson that has done more than anywhere to revive local heirloom wheats. The breads — country loaves, focaccia, the Heritage Wheat baguette — are made from grains grown within a hundred miles. Buy a loaf and you taste the entire ecology of the Santa Cruz valley.
The bakery opens limited hours and frequently sells out by noon. Pre-order through the website if you want to be sure. Also stocked at the Heirloom Farmers' Market on Saturdays.
