Different materials used to smoke malt result in unique flavor and aroma characteristics. Beechwood-, peat- or other hardwood (oak, maple, mesquite, alder, pecan, apple, cherry, other fruitwoods) smoked malts may be used. The various woods may remind one of certain smoked products due to their food association (e.g., hickory with ribs, maple with bacon or sausage, and alder with salmon). Evergreen wood should never be used since it adds a medicinal, piney flavor to the malt.  Excessive peat-smoked malt is generally undesirable due to its sharp, piercing phenolics and dirt-like earthiness. The remaining ingredients vary with the base style. If smoked malts are combined with other unusual ingredients (fruits, vegetables, spices, honey, etc.) in noticeable quantities, the resulting beer should be entered in the specialty/experimental category.
