What's the use of the remaining half bottle of white wine in the hotel? It's a shame to throw it away.

It's simple. When you meet this half bottle of white wine, put them all in a bigger container. After all kinds of liquor are mixed, it is a combination of base liquors with different styles and qualities. The style will not have a unique flavor like any kind of liquor. Maybe it tastes good. Give it a try, have a taste, and don't want to throw it away next time.
