eli5: What about the taste of wine actually gets better with age? Articles online describe flavor can improve over time, but not what about the flavor changes.

It depends on the wine, but generally red wines get less sharp and less…grape-juicy. They can develop undertones of earth, berries, nuts, truffle, etc. These flavors exist in younger versions of the wine, but they can be less pronounced and harder to find in a younger wine. Again, it really depends on the particular wine in question. Some wines age and don’t really change all that much or even taste worse, but that also depends on how they are produced and ultimately stored…and on the drinker’s preferences.

Flavor in general is a delicate thing, not just in wine.
