Bamberg-style Bock Rauchbier should have beech wood smoky characters that range from detectable to prevalent in the aroma and flavor. Smoke character is not harshly phenolic, but rather very smooth, almost rendering a perception of mild sweetness to this style of beer. The Bock beer character should manifest itself as a strong, malty, medium- to full-bodied with moderate hop bitterness that should increase proportionately with the starting gravity. Hop flavor should be low and hop aroma should be very low. Bocks can range in color from deep copper to dark brown. Fruity esters should be minimal. Diacetyl and chill haze should not be perceived.
