Boozy with a hint of citrus + sweet and some complexity and depth from the barrel-aged bitters and Bols Genever. Lingers in your mouth with a syrupy feel, a slight tingle and some sweet from the syrup. The Bols Genever is not my favorite, definitely a unique (and acquired?) taste. The bitters play well with the lemon and orange from Grand Marnier. A drink I could only have one of.
