On a beverage menu that shifts both subtly and frequently alongside the dishes at Tratto, one cocktail sticks around through the seasons: the Durum Old Fashioned. It should be said, though, that it has moving parts as well, as bourbons cycle through it at Blaise Faber's whim (sometimes it's Arizona Distilling Company's desert durum wheat whiskey, other times it's 107-proof W.L. Weller bourbon from Kentucky). But the mix is always secured by Faber's very own cordial crafted from Arizona-grown durum wheat and dates. The drink also gets dotted with Workhorse Rye coffee bitters, made by a friend in San Francisco with deep Tucson roots.
