How about giving him a cocktail mixing kit? It can include a shaker, strainer, bar spoon, measuring jigger, and some recipe cards. You could also add in a nice bottle of liquor, some unique bitters, and garnishes such as olives or cherries. Additionally, you could consider signing him up for a online mixology class or booking a private cocktail making class at a local bar.
Or you can get him a star map with the date when he was born.
