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.
Simple syrup: Simple syrup (aka sugar syrup, or bar syrup) is a basic sugar-and-water syrup used by bartenders as a sweetener to make cocktails. Simple syrup is made by stirring granulated sugar into hot water in a saucepan until the sugar is dissolved and then cooling the solution. The ratio of sugar to water is 1:1 by volume for normal simple syrup, but can get up to 2:1 for rich simple syrup. For pure sucrose the saturation limit is about 5:1 (500 grams (18 oz) sucrose to 100 millilitres (3.5 imp fl oz; 3.4 US fl oz) water).
