About 15 years ago my grandmother used to buy some fairly generic tequila called Newton at the supermarket in Mexico. Despite the less-than-stellar packaging and the unconventiinal name, it was some of the best tequila I ever had. Not only me, but my grandma, who's somewhat of a tequila connoisseur, with 5+ decades of experience under her belt, also agreed that it was some of the best she'd ever had. It rivaled Cazadores, Siete Leguas, and Don Julio, and was head and shoulders above Hornitos, Cuervo, Reserva del Patron, Sauza, and all the other brands that try to sell you gasoline in a bottle.
