Castle Constellation Wines in Sion, open July–November.
Perched at 1,950 meters elevation in the Valais region, Castle Constellation Wines commands sweeping Alpine vistas across the Rhône Valley and toward the Pennine Alps.
The estate's vineyard terraces cascade down the mountainside, creating a dramatic natural amphitheater for ceremonies and receptions.
Stone architecture and mature grapevines form an authentic Swiss mountain backdrop that shifts with season and light.
Great wines that I had the chance to taste at the Cave du Palais de la Justice in Geneve.
