Why do the Champagne and Prosecco regions produce sparkling wine?

The Champagne and Prosecco regions produce sparkling wine due to a combination of climate, soil, grape variety, and winemaking techniques. Champagne’s cool climates and chalky soils are ideal for growing the exquisite grapes of Chardonnay, Pinot Noir, and Pinot Meunier, which are used to make Champagne. On the other hand, the Veneto region in Italy has a mild climate that is ideal for growing Glera grapes, which are used to make Prosecco.
