G4 Tequila is produced at El Pandillo Distillery (NOM 1579) in Jesus Maria, Jalisco by Felipe Camarena, fourth-generation master distiller and son of the La Alteña family behind Tapatio and El Tesoro. Built on 100% estate-grown highland agave, a custom-built metal tahona, stone-oven cooking, and a unique 50/50 blend of rainwater and spring water, G4 is one of the most technically precise and terroir-driven tequilas produced in Los Altos.
