Pulling Nails pours a dark cola brown with a couple fingers of tan head that calms down to a thin layer over the top of the beer. The aroma is more of malty caramel and a barrel aged porter with yeast. The flavor is sour, but takes you on a journey of cola and dark fruit. We also picked up notes of coffee and caramel, a Belgiany yeast and some alcohol. The sourness builds upon itself and every sip brings a new flavor. The mouthfeel is medium to heavy and the carbonation is also heavy that lends a creamy foamy texture as you swish it in the glass. The alcohol is hidden, but comes out the more it warms up.
