Don Fulano Añejo is produced from 100% estate-grown Blue Weber agave piñas, slow-roasted in traditional brick ovens, then fermented with natural yeast and spring water filtered through local volcanic rock at La Tequileña (NOM 1146), Tequila, Jalisco. Following double distillation in copper pot stills, the tequila is aged for a minimum of twelve months in American white oak barrels — the standard añejo maturation period — developing notes of vanilla, dried fruit, and warm spice while retaining the estate-grown agave's roasted, earthy character. No additives, colouring, or flavour agents are used. Bottled at 40% ABV.

Don Fulano is produced at La Tequileña distillery (NOM 1146), located in the town of Tequila, Jalisco, Mexico. The brand was founded in 2000 by Enrique Fonseca and Sergio Mendoza, combining Fonseca's distillation expertise — gained through study in Scotland and Europe — with the Fonseca family's generational history of agave farming in the Highlands of Jalisco dating to the late nineteenth century. Don Fulano uses 100% estate-grown Blue Weber agave, is produced without additives, and ferments with natural yeast and spring water filtered through local volcanic rock. Ageing experiments draw on European cask influences including Limousin oak and ex-PX sherry barrels.
