Is it rude to bring only beer for yourself to a party?

I work in a senior building, and there is a party this week for a guy who lives here. It will be in his apartment. When giving his wife some supplies for the party yesterday, I saw what she is serving the spiked punch in. The containers are more like plastic bucket organizer baskets. I have no clue if only beverages have been in these containers. I would not like to drink from there.

Obviously, we could just drink water, no big deal. But I just had the thought to maybe bring two beers - one each for my husband and I. But then I wondered if that’s rude. So now I’m more curious what others think.

Worth noting, we drink craft beer. I have come to really not like inexpensive domestics, otherwise I’d buy a pack of Bud Light and be happy to share.
