The tradition of selecting grapes for making wine is known in Liechtenstein as "Wimmlete", a term also used to refer to the grape harvest itself.
On the day of the grape harvest, church bells would ring and friends and relatives would hurry to the vineyard owned by "their" winemaker to help. In return they would receive food and wine at the end of the day in recognition of their hard work. Even today people are still needed to help pick grapes during harvest time - why not have a go at it yourself?
