On the edge of the wine-growing village of Flasch in the Grinsons Rhine Valley stands a striking ensemble of buildings amidst the vineyards: The Gantenbein Winery where Martha and Daniel Gantenbein have been producing wine since 1982. They knew from the start that the vine is the key, so they planted Burgundy clones in their vineyards. They learned that it is vital for the grape to keep its quality on its way from the vine to the bottle, so they structured their production accordingly: The flow of the grapes and the juice is basedon the force of gravity, which means that neither pumps nor filters are needed. An area of 12.5 acres - and thus the largest part - is dedicated to Pinot Noir. Chardonnnay is grown on 2.5 acres, while Riesling covers an area of only .5 acres.
