Both red and white wines can improve with age, but many are ready to enjoy when released. Sparkling wines vary too: some develop during extended maturation, while Prosecco is generally chosen for fresh fruit and floral character. Keeping a bottle longer is not a guarantee of better wine.
Someone tells you to keep a red wine because it will improve. A white bottle receives the opposite instruction. It is a tidy rule, which may explain why it travels further than its accuracy deserves.
Some whites develop beautifully over time. Plenty of reds are ready when you buy them. The question belongs to the particular wine.
Why some red and white wines develop with age
WSET identifies flavor intensity and preservative qualities, including acidity and tannin, as important features. Their balance matters. A strong mouth-drying sensation alone is no promise of a rewarding bottle years later.
As wine ages, youthful fruit aromas can fade, other aromas develop and texture can change. Enjoying the result is a matter of taste as well as condition. Older and preferable are different judgments.
Ask about the bottle you actually own
Start with the producer’s drinking-window advice and the way the bottle has been stored. If you are considering cellaring a special wine, seek guidance about that wine and vintage.
A bottle intended for early enjoyment has a perfectly respectable purpose. You bought something to enjoy, and the producer may have made it ready for precisely that.
What about sparkling wine, including Prosecco?
Sparkling wines can age too. In the traditional method used for Champagne, time on the lees before release can develop aromas such as brioche and toast. That controlled maturation is different from leaving a finished bottle in a cupboard.
Fresh fruit and floral character are often part of Prosecco’s appeal. Saving it indefinitely can change the qualities that attracted you. For Bella Principessa, follow advice for the specific bottle rather than assuming extra years will improve it.
Our guide to how long unopened Prosecco can be kept explains the timing. Storing Prosecco covers conditions, and wine tannins explains the drying sensation often discussed in reds.
The interesting choice is when to enjoy the wine at its best for you. Its color cannot put that date in your diary.
