What should I do with expired wine in the bar?

You can't handle it yourself. The wine that has been opened, whether it is the guest's or the company's internal wine, should be registered according to the date and stored in a special wine cabinet. The wine list has three links: one for the bar, one for the finance and one for the guests. Remind guests to use wine in time. If it is overdue for a long time, ask the parties for advice.
