That bottle sitting on your kitchen counter isn't getting better with age.
It's getting worse.
A kitchen counter has far too many heat swings and light.
Your bottle probably only hasn't gone bad yet because it is laden with preservatives or was produced in a way that helped it hold up in the adverse environment of your kitchen or the global supply chain.
Even if it's holding up, it's not getting better.
Even if this wine is aged properly, it won't improve much. They can get away with it because most drinkers can't tell the difference and don't realize how much worse they feel after drinking it.
If you want a wine that ages well, find one that hasn't been heavily manipulated.
To store wine right, lay it on its side somewhere cool and dark. A basement, a garage that never warms up, or the back of a closet.
If you don't have a spot like that, buy a wine fridge, or just don't "age" wine. Chances are the wine you bought off the shelf won't change much with age anyway.
