In 1897 Orazio Nonino establishes his own distillery in Ronchi di Pavia. In 1933 the distillery moves from Ronchi to Percoto. Here, the Noninos introduce their “Aquavitae Optima”; a test which would lead to the creation of Monovitigno (single variety) Grappa. This grappa is distilled from the pulp of the Moscat grape immediately after pressing and fermentation. In order to guarantee the best quality of the distillates, Nonino only produces during the wine harvest.
