The top pick for many bartenders is blanco (or silver) tequila — unaged, crisp, and full of pure agave flavor. It cuts through the citrus and sweetness of a margarita with a clean bite that doesn’t get lost in the mix. Brands like Don Julio, El Tesoro, Fortaleza and Espolòn often top the list for their balance, quality, and traditional production methods. They’re not the cheapest on the shelf, but they deliver that agave-forward character that makes a margarita sing.
