WHERE’S PROSECCO FROM?

A couple of flutes of Prosecco wine.

Q. Where is Prosecco sparkling wine from? Thanks, Dennis C.

A. Prosecco is from Italy, northern Italy in fact, the region called [the] Veneto. Here's a bit from something I’ve written previously on Veneto: “Three of Veneto’s wines are very familiar to American wine drinkers, three being Soave, Valpolicella and Prosecco, this last having bubbled its way close to the top in popularity for Italian sparkling wine.

Its full name is Prosecco Superiore Valdobbiadene Conegliano DOCG (whew) and it is made of a grape little known to us, the Glera. This soft, fruity, light, fizzy white wine slakes thirst like few other bubblies and its price is remarkably low (usually $10-$15 a bottle). It is the wine of Venice and the base of that city’s famed aperitif, the bellini.”
