Prosecco: Prosecco is an Italian DOC or DOCG white wine produced in a large area spanning nine provinces in the Veneto and Friuli Venezia Giulia regions, and named after the village of Prosecco which is in the province of Trieste, Italy. It is made from the Prosecco grape (renamed Glera in 2009 within the European Union) but denomination rules allow up to 15% of the wine to be other permitted varieties. Prosecco is almost always made in sparkling or semi-sparkling style (spumante and frizzante, respectively), but a still wine (tranquillo) is also permitted. Within the larger designation are two small DOCG areas, Conegliano Valdobbiadene Prosecco in the hills between the towns of Conegliano and Valdobbiadene, and Asolo Prosecco around the nearby town of Asolo. Prosecco Superiore is always spumante and comes only from these DOCG areas.
Soda water: Carbonated water (also known as soda water, sparkling water, fizzy water, club soda, water with gas or (especially in the U.S.) as seltzer or seltzer water) is water containing dissolved carbon dioxide gas, either artificially injected under pressure or occurring due to natural geological processes. Carbonation causes small bubbles to form, giving the water an effervescent quality. Common forms include sparkling natural mineral water, club soda, and commercially-produced sparkling water.
