Schneider is one of the world’s great brewers of wheat beers and Aventinus is a great beer, though not what most people think of as a Weizenbier. As you say, it’s a Doppelbock with tons of malt plus that spicy fruitiness characteristic of wheat beers. These sorts of brews are pretty nice on a chilly spring evening. I’ve had the Schneider Aventinus Weizen-Eisbock and it’s similar but even more extreme (12% alcohol I think and slightly syrupy). It comes in a small 330 mL bottle and I can’t imagine drinking more than one. Just the thing for a winter nightcap.
If you like Schneider Aventinus, you might want to try Weihenstephaner Korbinian. It’s along the same lines as Aventinus but not quite as intense (not necessarily a bad thing). Weihenstephaner, another wheat beer specialist, claims to be the world’s oldest brewery and makes what is probably my favorite Hefeweissbier. Here’s what the Korbinian looks like.
Picking up Korbinian at Binny’s, I noticed some bottles of Iron City I hadn’t seen before (not that I was looking). While not a huge fan of Iron City, I always thought it was better than your usual “yellow beer.” Anyway, this comes in a 12 ounce aluminum bottle. Ironic, no?
