On tap at Ambulance, luxuriously rich cask-conditioned nightcap (with bold 16.5% ABV) retains creamily chewy brown-sugared black chocolate syruping and massive maple molasses sapping. Dark cocoa, toffee, coffee, burnt caramel, creme brulee and caffè macchiato illusions given dried-fruited black cherry, raisin and prune pureeing as well as burgundy-wined bourbon whir at sweetly candied mocha finish.
