The mild climate and quite regular rainfall favor the ripening process, leading to good acid balance and sugar values. Most Prosecco, whether DOC or DOCG, is made as Spumante sparkling wine or Frizzante (semi-sparkling). Prosecco DOC Spumante is the most famous and popular variety, with longer-lasting bubbles. Prosecco DOC Frizzante has bubbles that linger for a shorter time. A small proportion is made as Tranquillo (still wine), with no bubbles. [5] Tranquillo amounts to only about 5% of production, [21] and this wine is rarely exported. Depending on their sweetness, in accordance with the EU Sweetness of wine Regulations for Terms used to indicate sweetness of sparkling wine, Proseccos are labelled "Brut" (up to 12grams per litre of residual sugar), "Extra Dry" (12–17 g/L) or "Dry" (17–32 g/L). [28] Extra-Dry has been the dominant style made, but the amount of Brut is now increasing.

Except for Col Fondo and any Método Classico Prosecco, most Prosecco does not ferment in the bottle. Usually, it should be drunk young, [41] preferably within three to five years [43] of its vintage. However, high-quality Prosecco may be aged for up to seven years. [44] a b Blyth, Mark (31 December 2021). "How the politics of prosecco explain what took the fizz out of the Democrats".

Since the 2000s, Glera grapes are cultivated and wine produced in other countries including Brazil, Romania, Argentina, and Australia. [3]Glera grapes are grown on plains or on slightly sloping areas, with alluvial medium-textured soils rich in clay. The view that Prosecco cannot be aged has been challenged by other experts. A tasting in 2013 of wines produced between 1983 and 2013 demonstrated the longevity of the wines from one of their top producers.
