You’ve brought a bottle of wine to a party, but no one’s opened it. Can you take it back? That’s an important question to ask yourself. You can’t be offended if the person who opened it didn’t care for it. It might be a special bottle that represents your personal taste, or it might just be a mistaken assumption. It’s not a bad idea to offer to return the bottle if you’re invited to a party, but you can’t just walk away.
First of all, don’t assume that just because someone opened your wine doesn’t mean they’ve had it. It’s always nice to be polite and say so. This way, if your wine isn’t to your liking, you’ll know that you’ve done your best to pick a wine that will complement the meal and the food you’re eating. However, if your dinner is a complete disappointment, the wine will never be returned.
You’re stuck with this problem. No one opened the wine you brought, and you don’t have a way to take it back. If this happens, you should explain why you chose the wine and give them a taste. If you know that they’re not a fan of wine, then you’re better off taking it back and not wasting the wine.
