Eight grape varieties grow on two sites on the southern slope of the Ottenberg hill with a clear view over the Thur valley to the Alpstein and Säntis. Two thirds of the vines are located in Bründlerberg, one third in Waidli and Bachtobel area. The grapes are processed into 12 wines. The soils lie on a glacial moraine and are rather heavy. The terroirs are clayey-loamy and rather heavy. Since 1975, the Wolfer Winery has been a self-wine-pressing operation.
The geographical location of the Wolfer winery combines heavy terroirs with a view that reaches as far as the Alpstein and Säntis. World-class wines that are part of the memory of Swiss wine thrive here.
