Ryan and I have been saving this for a needed occasion. We've had several in this series and they are always good. Saint Arnold is a great Houston brewery and if you're ever in Houston and like beer you have to go there. Modest head and the color is a deep brown but not opaque, a little light gets through this clear liquid. Aroma is wonderful. Oak barrel and woodsy, alcohol that brings bourbon and a sweetness that's yet unidentified. First thing I noticed is that it's has a lot of effervescence in the mouth. But not in the head. A heavy wood oak barrel begins the flavor profile. Bourbon whiskey, espresso and coconut all blend perfectly. A hint of chocolate hides in the background. There's a strong sweetness that's mostly from the bourbon but tastes like maybe a little molasses also. Late in the finish I get just a little nondescript citrus pith bitterness. As it warms the bourbon produces a smooth alcohol that begins to dominate. I really like this beer. There are moments when it has a blend of flavors reminiscent of German chocolate cake. Ryan was a bit put off by an abundance of effervescence but I swirled the glass and it made no difference to me. As usual, the Bishop Barrel series is fabulous.
