Generally all malt, but can include up to 25% wheat malt and some sugar adjuncts. Any hop variety can be used. Clean American, lightly fruity English, or Kölsch yeast. May also be made with lager yeast, or cold-conditioned. Some versions may have honey, spices and/or fruit added, although if any of these ingredients are stronger than a background flavor they should be entered in specialty, spiced or fruit beer categories instead. Extract versions should only use the lightest malt extracts and avoid kettle caramelization.
