Switzerland's core vine-growing districts are located around its edges, leaving the centre is largely vineyard-free. The majority are located in the south-west around the northern side of Lake Geneva (Geneva and Vaud) and along the upper stretches of the Rhone River in the Valais. There are also significant vineyard areas in the west (Neuchatel), the south (Ticino), the east (Graubunden) and scattered around Zurich in the north (Aargau, Schaffhausen and the Zurcher Weinland).
