Shadow of a Doubt Imperial Porter (9.86% ABV): Shadow of a Doubt was named after the great Hitchcock movie filmed in Santa Rosa in 1943. This beer pours a black color with dark brown hue and rich tan foam that leaves a persistent lace webbing on the glass. Shadow of a Doubt has a rich cocoa/chocolate and roasted malt aroma with background of dark coffee. The beer is medium to full-bodied with mild carbonation. Shadow of a Doubt provides rich, delicious, and balanced flavors of cocoa and chocolate, roasted malt, coffee, and light smoke. A wonderfully subtle hops bitterness and hints of tobacco accompany the slightly dry finish. This world-class beer is addictive and demonstrates the same type of creative, dark genius Alfred Hitchcock poured into his movies.
