Why are some wines better suited to aging than others?

I’ve always heard that certain wines get better with age, but what makes a wine “age-worthy”? I mean, what happens to a bottle that makes it improve over the years, while others are best when fresh? Is it about the grape variety, the tannins, or something else? Any wine lovers out there who can break this down for me?

Age-worthy wines typically have higher acidity, tannins, and complex flavor profiles, allowing them to develop and mature over time. Factors like grape variety, terroir, and winemaking techniques also play crucial roles. While some wines are best enjoyed fresh, the right components can make others truly shine with age.
