I drink but he doesn't?

So I'm going out with this guy and both of us are 20. I drink and he knows I do. It isn't all that often, but he knows that I enjoy a nice glass of wine every once in a while and occasionally go to parties where there is alcohol. He does not drink. He wants to wait until he's 21. Now, I'm planning on having a date night where he comes over to my place to have dinner and watch a movie. I would like to have a glass of wine with dinner. Do you think that would make him feel excluded or weird?
