Use a darker beer of any kind for more flavor if you've got it. Anything that says u003cstrongu003edarku003c/strongu003e on the label is good. u003cbr/u003eu003cbr/u003eFor the best results, use something that is a Dark Lager, Dark Ale, Stout, or Porter; or even one of the lesser known u003cemu003eDunkelu003c/emu003e and u003cemu003eSchwarzbieru003c/emu003e styles. If all you've got is an IPA Bock or Amber Lager, that's fine too.
