Asti or Asti Spumante is a DOCG white sparkling wine prouced in an area to the south of the town of Asti in Piedmont, Italy. Made from the Moscato Bianco grape, it is sweet and low in alcohol, and often drunk with dessert. It retains its sweetness through a complex filtration process. Another wine called Moscato d'Asti is made in the same region from the same grape, but produced by another technique which differentiates it from Asti.
