don't bring any wine with which you are too emotionally involved. For any wine you are thinking about, ask yourself how you would react if one of your uncles hated it. If you start to flare up at the thought, bring something else. Bring more than one bottle, and make them very different. Even your orneriest relative should try to find something to like, given multiple choices. We all know some wines are easier for novices to appreciate than others. If you want to spring a cool-climate Syrah on them, also offer the option of a crisp Sauvignon Blanc. Inoffensive is not a bad word in this context.
