The white Muscat grape grown to produce Asti docg originates in southern Piedmont, in an area officially delimited since 1932. Covering a total of 9700 hectares, comprising 52 communes and over 4000 businesses in the provinces of Alessandria, Asti and Cuneo, it lies to the right of the river Tanaro in the rockless hill system of the Langhe and Upper Monferrato (cartina_Asti.pdf).
Asti docg comes exclusively from the only vine, the white Muscat, which can generate a delicate and intense, fragrant and persistent sparkling wine. The peculiarities of this vine, well-known to viticulture in the past, are exalted by the climatic and geographical characterisitcs of the area of production. Indeed, according to the deepest knowledge of the interactions between vine and environment, the best results in terms of aromatic varietal component, fineness and balance between acid and sugar are reached on limestone terrain, like the Asti docg area of production, and in environments with a micro-climate typical of its hilly zones. It is precisely the precious aromatic substances (linalool) produced by the white Muscat grape in the final weeks before harvesting which reach their maximum build-up in the grape at the beginning of September.
This is when the harvesting operations begin, carried out by hand to transfer intact from grape to wine the aromatic heritage which is the true characteristic of Asti docg and Asti Muscat docg.
