During the 19th century, in agricultural areas, each home in the High-Jura kept livestock and cultivated their own cereal. Many mills worked on water. In Vulvoz, the structure that housed the mill straddled the Perrine waterfall. Each peasant would bring their harvest there. Barley, oats and grinding waste served to feed the livestock, whilst wheat was used for men. In 1930, the structure over the Perrine was turned into a hydropower plant. The electricity, carried to the village, was used to run a new, more accessible mill. In 1960, the operator closed its doors for good.
