What beverage goes with cabbage rolls?

It's called beer. (And I'm a wine snob.) A dark one, like a porter or stout, is especially good. If your corned beef was braised in beer, well, then no other beverage but beer will do. However, if you MUST drink wine, then a Beaujolais or Beaujolais Village is okay. If you don't like reds, then an off-dry Riesling might do the trick.
