The Azanza Company was founded by José María Velasco Azanza Pérez in 1810. Little by little the company was consolidated and strengthened by achieving major successes.
In 1893 his son, José María Azanza, participated in the Fourth World Fair Exposition in Chicago in 1893 with a sample of their products.
In 1912, another descendent, Mariano, was present at the National Viticulture Congress celebrated in Pamplona, that had a great impact in the sector. Mariano continued with the family legacy within the world of viticulture and distillation.
