First created at a bar called La Capilla in the town of Tequila by Don Javier Delgado Corona in the 1960s, the Batanga is a favorite among fans of agave spirits.

You can experiment with whatever Fernet you have on hand, but Ignacio "Nacho" Jimenez says Fernet-Vallet will bring a deeper bark-like dryness to the mix.
