5oz at brewery. Looks very thick and muddy brown. Aroma is not acidic, low on assertive black malts (explains the color). Sort if baked goods maltiness with some cocoa and lightening mineral maltiness. Flavor is mild big. With soft malts and sweetness creating a full flavor. Some light malt bitterness at the end. Full rounded and mineral lightness on the finish. Low hops. Rare type of Impy nowadays.
