According to newly released figures from the Swiss Federal Office of Agriculture, a total of 280 million liters of wine were consumed in the country last year.
The increase is in line with the population growth, the office said in a statement. Consumption of foreign wine rose most, increasing by 7.8 percent and imported vintages accounted for 62 percent of all consumption.
Swiss wines are making up lost ground, with the popularity of home-grown vintages having fallen in previous years. Swiss red wine was up 4.2 percent, while consumption of Swiss white wine was up 2 percent.
Canton Valais remains the biggest wine producing area in Switzerland, with 5,042 hectares under cultivation, followed by Canton Vaud (3,818 ha) and Canton Geneva (1,433 ha).
