Formed in 1969, Winzerwy is a Cooperative Association started by a group of small Swiss German wine makers to assure quality and improve marketing, The members grow, harvest, vinify and bottle on their own premisis. The Winzerwy trademark guarantees for the finest quality Swiss wines with a recognizable varietal, vintage and Terroir.

It's rare to describe a museum as “welcoming”, but the Viticulture Museum is welcoming. Located on the peninsula Au (near Wädenswil) on Lake Zürich, the Viticulture Museum is both a museum and a focal point for people interested in Swiss wine and wine making. It offers both a historical perspective as well as addressing changes confronting Swiss winemakers today. On the day I visited they held a demonstration of barrel making, which is an endangered craft: there are currently three barrel makers in Switzerland and only one apprentice.
