Why does wine need to age? Can it age theoretically forever?
In: Chemistry
Why does it “need” to age? It doesn’t “need” to but there are chemical changes that happen gradually since there is no real perfect seal and things like oxygen will react with the wine. This changes the flavor of the wine and what one prefers is completely subjective. In particular, age might cause some of the harsher tasting compounds in wine to dissipate which leads to what is described as a “mellower” tasting wine.
Nothing is forever. So no, wine cannot age forever. Many old bottles use cork which will deteriorate over time – letting in air and therefore likely spoiling the wine. Generally speaking, it would have to be pretty ideal conditions to age red wine past 20 or so years. And most white wines probably won’t last much beyond 10 years.
There may be certain vintages that have a reputation for great taste that some might want to preserve. Other than that, there is of course the “status” of drinking something rather old and likely expensive.
