Boulevard Brewing Co. The Six Glass Quadrupel Ale, 10.2% ABV picked up from my local Total Wine comes from Kansas City, Missouri and is a Belgian Style Quadrupel Ale with 22 IBUs (International Bittering Units) pours a deep brown color with a one and a half beige head that slowly fizzes down to a nice halo giving you aromas of sweet dark fruits, plums and raisins with alcoholic boozy notes that takes you to the flavor of more dark fruit taste with a strong note of boozy alcohol with touches of sweetness coming through with a nice sweet boozy dark fruit finish and aftertaste of boozy dark fruits with a fuller mouthfeel. The Six Glass Quadrupel Ale is slightly thinner tasting than some other Belgian Quadrupel Ales, still a good one but I think there are better ones out there so I give Boulevard Brewing Co. The Six Glass Quadrupel Ale a B. The mouthfeel could have been a little fuller and there could have been more robustness in the dark fruits but not a bad Belgian style Quad. Something that I would recommend? Yes, this is one that you should try, it nice to see how an American craft version of a Belgian Quad stacks up to a real Belgian Quad, and it to okay but not better. Cheers! please enjoy responsibly!
