Fortaleza Tequila Reposado - 100% estate grown Blue Agave Tequilana Weber, and aged in oak barrels for 6-9 months. Guillermo Erickson Sauza is a fifth generation tequila maker who hand-crafts beautiful, artisanal tequila at his century-old estate. His tartabuelo (great-great-grandfather) Don Cenobio was the first person to export tequila to the US, way back in the 1860s, starting his own brand in the 1870s. That tequila (Sauza) was passed down the generations before being sold my Guillermo's grandfather in 1976. Tequila Fortaleza is a return to his roots, and to the traditional methods, including the use of a stone mill called a Tahona to crush the agave, a small, copper pot stills to destill the fermented agave mosto. The resposado is aged in barrel for up to nine months and no less than six, and is authentic tequila, the kind that would make Sauza's ancestors proud.
