4) Frizzante and Spumante mean different things
You may have seen some Prosecco labelled either as ‘Spumante’ or ‘Frizzante’. Frizzante is technically ‘lightly sparkling’, and doesn't keep its fizz as long as spumante, which means ‘fully sparkling’, will. You can usually tell a frizzante by the special piece of string over the top of the cork. This is know as a ‘spago’ opening. Frizzante is usually cheaper than spumante, too. Sometimes you can also find still Prosecco wines, called ‘tranquilo’ wines. They are quite hard to come by, though.
5) There are different sub regions and quality levels for Prosecco
Prosecco is never just Prosecco. It comes from Northern Italy and can be grown in nine provinces spanning the wine regions of the Veneto and Friuli Venezia Giulia. The most important thing to note here is that quality Prosecco starts with DOC on the label (Denominazione di Origine Controllata) which essentially means it’s been made in a controlled zone of production. If you want to go higher in quality, look for DOCG (Denominazione di Origine Controllata e Garantita). Like many parts of France, Prosecco from the DOCG quality level can now put their village on the label (look for ‘Rive di…’), which ostensibly points to subtle differences in terroir characteristics. Did you know there was also a kind of ‘Grand Cru’ of Prosecco too? It’s called ‘Cartizze DOCG’: the name of a hill 1,000 feet high which, arguably, grows the best grapes of all due to altitude and ripening ability.
