Beers for the Non-Hopwhore

Sounds to me you're more of a malt guy especially if you like the Octoberfest brews.
Try any Festbier. HeBrew has a few maltier beers. I'd also suggest some great brown ales such as Dogfish Head's Indian Brown Ale or any Altbier for that matter.
Lastly, dopplebocks will fit your bill perfectly in my opinion. Ayinger Celebrator is a slamdunk as is Troegenator Double Bock (one of my favorites) and Weihenstephaner Korbinian. Enjoy and good luck on your beer discoveries!
