However the story goes that it wasn't until the early 1900s that Félix's son, Aurelio López Rosales, found a horseshoe while out inspecting the agave fields. With this symbol of good fortune, Aurelio named his excellent 100% Agave Premium Tequila after the Spanish for horeshoe - Herradura. Remaining in the family for five generations, it wasn't until 2007 that Casa Herradura, including the distillery, agave fields and the Herradura brand, along with their sister brand of El Jimador, was sold to the diversified American wine and spirits company Brown-Forman. For those interested in the history of Herradura and Tequila production in general, jump on the Tequila Express and visit Casa Herradura and its Old Factory museum, in the town of Amatitán.
