The aroma should be a pleasant balance between the expected aroma of the base beer (e.g., robust porter) and the smokiness imparted by the use of smoked malts. The intensity and character of the smoke and base beer style can vary, with either being prominent in the balance. Smokiness may vary from low to assertive; however, balance in the overall presentation is the key to well-made examples. The quality and secondary characteristics of the smoke are reflective of the source of the smoke (e.g., peat, alder, oak, beechwood). Sharp, phenolic, harsh, rubbery, or burnt smoke-derived aromatics are inappropriate.Appearance: Variable. The appearance should reflect the base beer style, although the color of the beer is often a bit darker than the plain base style. The appearance should reflect the base beer style, although the color of the beer is often a bit darker than the plain base style.As with aroma, there should be a balance between smokiness and the expected flavor characteristics of the base beer style. Smokiness may vary from low to assertive. Smoky flavors may range from woody to somewhat bacon-like depending on the type of malts used. Peat-smoked malt can add an earthiness. The balance of underlying beer characteristics and smoke can vary, although the resulting blend should be somewhat balanced and enjoyable. Smoke can add some dryness to the finish. Harsh, bitter, burnt, charred, rubbery, sulfury or phenolic smoky characteristics are generally inappropriate (although some of these characteristics may be present in some base styles; however, the smoked malt shouldn't contribute these flavors).Varies with the base beer style. Significant astringent, phenolic smoke-derived harshness is inappropriate.This is any beer that is exhibiting smoke as a principle flavor and aroma characteristic other than the Bamberg-style Rauchbier (i.e., beechwood-smoked Märzen). Balance in the use of smoke, hops and malt character is exhibited by the better examples. The process of using smoked malts more recently has been adapted by craft brewers to other styles, notably porter and strong Scotch ales. German brewers have traditionally used smoked malts in bock, doppelbock, weizen, dunkel, schwarzbier, helles, Pilsner, and other specialty styles.
