Champagne Papi is trading bubbly for beers … because Drake went all the way to Germany to hit up Oktoberfest.

Drizzy just posted a photo dump from his Oktoberfest adventure … and he got in the spirit, because he’s wearing his own custom lederhosen.

Drake looks like he’s rolling with his entourage … and everyone in the group grabbed a big mug of Germany’s finest beer and chugged.

Check out the photos … it looks like Drake and the crew had a helluva time.
