What happens to wine when the cork dries out?
But cork loses its elasticity and resilience over time, and an older cork won’t expand as well as a fresh one—especially if it dries out, which can cause it to become quite brittle and crumbly. (That’s why it’s so important to store wine bottles on their sides, so that the cork doesn’t dry out.)

Why is my wine cork black?
