On tap at Ambulance Brew House, fully expressive dark-roasted mocha malt creaminess nearly overwhelms dark-fruited constituency. Coffee-sugared black chocolate frontage, black patent malt subsidy and dark cocoa reminder get soaked in sappy molasses as blackened charcoal-singed hop bittering deepens the contagious mocha prominence. Burgundy-wined black grape and black cherry tones settle beneath the surface. In the can, thickly frothed mahogany-bodied Cascadian Dark Ale seeps black malted dark chocolate bittering into mild coffee sugaring and ashen hop-roasted nuttiness as well as IPA-suited orange peeled yellow grapefruit twist.
