Start with curiosity, not a correct answer.
Try a small pour and notice your first reaction. You do not need to identify a grape, a place, or a list of aromas. “I like that” and “not for me” are useful observations.
Take a small sip if you want to explore further. An aroma you do not enjoy does not always predict your reaction to the taste. There is no need to finish a wine you do not like.

People sharing the same bottle may notice different things. Talking about those differences—and the meals or gatherings they bring to mind—is part of the experience. Skipping a taste or choosing not to drink is always welcome.
