Many years ago, on the vine-clad slopes of the Lake Biel region, winegrowers were busy trimming the vines during the winter months. The cold north-east wind made sure that everyone working in the vineyards was frozen.

Someone had the idea of cooking a sausage in the hot steam issuing from the cover of the distilling vessel.
