ZANTHO wines are created in collaboration between Josef Umathum and Wolfgang Peck in the Andau wine cellar. Josef Umathum guarantees the high quality of the grapes produced and is responsible for quality management in the vineyards. Wolfgang Peck, managing director of the Andau wine cellar, is the oenologist responsible for the vinification. Together, typical regional wines are produced from local grape varieties on almost 70 hectares of vineyards.
