Prosecco

Opened prosecco loses its fizz after 1 to 3 days. Unopened it carries no date and keeps one to three years — best drunk young.
No date — but still not forever
Prosecco is one of those drinks you search in vain for a best-before date. At around 11 percent alcohol it sits above the 10 percent mark and is therefore exempt from a best-before date under EU law. But no date does not mean it keeps forever — with sparkling wine, rather the opposite is true.
Prosecco is a fresh, fruity sparkling wine not made for ageing. Unopened and kept cool, it holds its quality for about one to three years, after which freshness and fizz fade. Unlike fine Champagne, prosecco does not gain from storage — it tastes best young.
Once opened, the carbonation is the limiting factor. With a sparkling stopper and chilled, opened prosecco keeps its fizz one to three days; without a stopper it is often flat by the next day. A proper stopper preserves the bubbles far better than the often-heard spoon-in-the-neck trick, which is proven to be ineffective.
The closure is a good guide to handling: sparkling wines with a classic cork and wire cage are under pressure and should always be opened well chilled so nothing foams over. After opening, a dedicated metal sparkling stopper best preserves the fizz. If you only want half a bottle, chill the rest again straight away — the colder the prosecco, the more slowly the carbonation escapes, so the second day stays lively.
How do I spot bad prosecco?
Spoiled or flat prosecco shows clearly:
If no bubbles rise, the prosecco is flat. Not a safety issue, but no pleasure.
A stale, slightly vinegary or bready taste shows oxidation.
Clear darkening or cloudiness points to an over-aged wine.
Pour a glass and watch the bubbles: if fine bubbles rise and form a bead of foam at the rim, the prosecco is fresh. If no bubbles appear and the wine looks still, the carbonation has escaped and the prosecco is flat.
Shelf life at a glance
State and stopper decide between days and years:
| State | Shelf life |
|---|---|
| Unopened, cool & dark | 1–3 years |
| Opened with a stopper | 1–3 days |
| Opened without a stopper | about 1 day |
| Once poured | drink promptly |
Store it right
The right storage keeps prosecco fresh longest:
Cool and dark — stored steadily cool, away from light and heat.
Store upright — sparkling wine stands; the pressure keeps the cork moist.
Use a stopper — best preserves the carbonation after opening.
Serve well chilled — cold, prosecco keeps its bubbles longer and tastes fresher.
Common myths
A few myths surround prosecco:
No — prosecco is a young sparkling wine that loses freshness over the years. The missing date is a legal exemption, not a quality guarantee.
A myth — proven ineffective. Only a tight stopper really helps.
No — prosecco is drunk young and fresh; it is not made for ageing.
Flat prosecco is not lost: it works for sorbets, for deglazing in the kitchen, or in an aperitif cocktail where the missing fizz goes unnoticed. So a leftover does not go down the drain.
