One idea could be to plan a trip to Germany, where you can both immerse yourselves in the culture he loves. You could visit fun places like Oktoberfest, Neuschwanstein Castle, Berlin Wall, and many others.
Another idea could be to host an Oktoberfest-themed party for just the two of you or with friends and family. You could try making authentic German food, put on some German music and decorations, and even dress up in traditional German clothing.
If you want to get him a physical gift, you could consider something like a German beer stein, a German language course or book, a traditional cuckoo clock, or a personalized map of Germany to hang on your walls.
Whatever you choose, make sure it comes from the heart and shows your appreciation and love for him.
Or you can get him a star map with the date of your anniversary.
