The legal drinking age in Switzerland is 18 years old. This applies to all alcoholic beverages, including beer, wine, and spirits.
While the legal drinking age is 18, it's important to note that some cantons may have additional regulations regarding alcohol consumption in specific locations, such as bars or clubs. For example, some cantons may require individuals to be 20 years old to enter certain establishments.
It's always advisable to check with local authorities or establishments for any specific restrictions before consuming alcohol.
