We're growing grapes organically on 14.5 hectares in the Mosel Valley, mainly on steep slopes. In the last 5 year we have planted more than 3.5 hectares of Piwis (new hybrids)as part of our 7 hectare vitiforesty project. We produce 11 different natural wines with zero additives which make up about 55% of our production. For the other 45 % w still produce some classic Mosel styles using sterile filtration, but without addtives except sulfites.
