It will continue to get better if you keep it in the following conditions:
1) Out of light
2) Decent amount of humidity 50%+
3) Cooler temperatures lets say 55-65 degrees (that doesn't fluctuate much day to day)
Keep in mind not all wines get better with age. And they all have their time limits as well.
If you want to buy some newer age worth wines, they may require a few hours of decanting prior to drinking if you want to drink them young.
