At Proof, we believe bread is more than food - its nourishment of connections, memory, and craft. We are committed to baking 100% naturally leavened sourdough, stone-milling heritage and local grains ourselves to honor tradition, flavor, and Mother Nature. Every loaf tells a story of patience and intention, shaped by hand and baked fresh daily. Proof is a rebellion in which old world techniques meet modern community to battle modern-day apathy and awaken the human spirit one crumb at a time. Based out of Phoenix, Arizona. #sourdough #bread #bakery #naturallyleavened #heritagegrains #arizona #phoenix #mesaaz #litchfieldpark
