Without cheating what is the bottom of a wine bottle called?

James R Us The sad part.

Schmoo📎 James R Us My Dad called to ask me how long wine lasts after you open it.
I said, i don’t know, a couple hours??
He said, no, after it’s been open a couple of days.
I said, I don’t know, I’ve never had wine left to save.

Sherri Schmoo📎 James R Us 🤥 After a couple of days left open, you can use it as vinegar.
