The Clos Mathis belongs to Ostertag's long-time, freshly retired vineyard manager, Hubert Mathis. This remarkable 0.6-hectare vineyard surrounded by stone walls is located in Ribeauvillé, in line with the grand crus Geisberg and Kirchberg. The soil is composed of a granitic mother rock and gneiss, with poor fertility. The vines are grown on terraces, on a very steep south-east facing slope which benefits from hot days and cool nights. The heat is tempered by cool winds coming down at night from the valley that ends just after the vineyard. This particular location allows slow ripening, preserving acidity and finesse in Riesling.
