I absolutely love Weihenstephaner’s Korbinian Dopplebock.
For me, the perfect dubbelbock is rich, very sweet, malty, bready, and has just enough hops to balance it out...not giving it a particular hop taste.
Korbinian is good and I do buy it but I’ve had brown ales richer than it. I knock them all the time but Sam Adams makes a better dubbelbock.
