The history of Almadén shows one of the first steps towards the internationalization of the Brazilian grape and wine industry. It was established in the Campanha region based on a study carried out by the UC Davis University in 1973, which indicated that the area was favorable for grape growing. Foreign investment started the business, but it was soon identified as a legitimate representative of the Brazilian wine industry. Since 2009, the brand has belonged to the Miolo Wine Group, which grows 23 varieties there. While it has some of the oldest vines in the country, the vineyards have been modernized for the production of high quality grapes.
