Lavaux is one of the most beautiful wine regions in the world. UNESCO-listed since 2007. A belt of terraced vineyards along the north shore of Lake Geneva, first planted by Benedictine monks in the 12th century. Vines dropping into the water. French Alps across.
The problem with Lavaux is finding somewhere to actually sit and drink it.
Leave cash in the box. Take a bottle. Sit on the patio with the lake below you and the Alps across the water. An A+ way to spend an afternoon.
Domaine Saint-Amour is the answer. Take the train, walk up through the vines. Small caveau, stone patio, the wine made on the slope behind you. On Sundays the rest of Switzerland is closed. The door here is still open. Fridge stocked. Honour system.
