What country makes the most sparkling wine in the world?

C.

Every year since 2016, Italy has made more spumante (“sparkling wine” in Italian) than any other country in the world according to the OIV (International Organization of Vine and Wine). Italy’s achievement has been driven in large part by the skyrocketing success of Prosecco which, at 660 million bottles a year, now makes up more than 10% of all Italian wine produced. Other major types of Italian sparkling wines include Lambrusco, Franciacorta, and Asti.
