Prosecco is generally enjoyed for its freshness, so follow the producer’s drinking-window advice and store it somewhere cool and dark. There is no single expiry date for every bottle. A special occasion need not become an appointment that keeps being postponed.
The bottle was a present. You put it aside for something special, and several perfectly pleasant evenings have since passed without quite qualifying. Now the wine has become a small obligation in the cupboard.
Before saving it any longer, check what the producer recommends. Time changes wine; it does not automatically reward patience.
How long should you keep unopened Prosecco?
The Conegliano Valdobbiadene consortium says its Prosecco Superiore shows its qualities fully in the year following harvest, while describing how aromas mature over time. The Prosecco DOC tasting guide also recommends enjoyment in the year after harvest.
Those are freshness recommendations, not universal expiry dates or a one-year countdown starting at purchase. The particular wine, bottling and storage history all matter.
For Bella Principessa, check the advice for the bottle you have. An exact drinking window needs product information, rather than a guess based on how long you remember owning it.
How long can Prosecco rosé be kept?
Do not treat two years as a guaranteed keeping time for Prosecco rosé. Follow the producer’s advice for the bottle you have, considering its vintage, bottling information and storage history. Once opened, use the separate guidance below for keeping Prosecco after opening.
Read the year in context
A harvest year identifies the vintage. It does not automatically give you the bottling date or the last day the wine should be opened. If you need help, send the producer or retailer a photograph of the label and lot code.
That is more useful than asking an old bottle to account for every cupboard it has visited.
Choose the occasion and store it well
Keep the wine cool and away from light and heat. Our storing Prosecco guide explains suitable conditions. A bottle left in a warm kitchen for an unknown period may not resemble one with a known storage history.
If you are planning an important meal, choose a bottle whose condition you can reasonably assess. Once opened, different considerations apply: see keeping Prosecco after opening.
For the wider question of improvement with time, read ageing red and white wine. Freshness can be the pleasure you bought the wine for. It need not wait for a grander invitation.

The Prosecco DOC tasting guide also recommends a large tulip glass, cool and dark storage, and enjoying the wine in the year after harvest. This is general enjoyment guidance, not an expiry date.
