A drink for a Xmas toast?

I have found some lovely etched vintage sherry glasses from WWII. I also have 3 adult children with spouses. Some drink some don’t. I would love to make a toast Christmas night to our children and make it a tradition. I have no idea what to serve. I know it’s only August but…I’m excited. What’s something yummy? Something I can count on to be a yearly tradition. It will only be one drink so no worries about strength. I am really looking forward to this. Btw I don’t drink. Used to drink beer as a kid. But am excited for the new tradition. Thanks for your kindness.
