Wine service refers to the proper techniques and etiquette involved in serving wine to guests. This includes selecting the right wine glasses, pouring the wine correctly, and ensuring the wine is at the appropriate temperature. A key aspect of wine service is the presentation of the bottle, which involves showing the label to the guest before pouring. The server should pour a small amount for tasting, allowing the guest to confirm the wine's quality. Proper wine service enhances the overall dining experience and showcases the wine being served.
