Profound Belgian quadrupel aged two years in Heaven Hill bourbon barrels retains creamy mocha sweetness and dried fruited intensity. Rich brown chocolate-spiced dry bourbon entry gains subtle Scotch whiskey boozing as raisin-prune-date conflux, candi-sugared caramel malting, sweetly soured red wine esters and musty cellar funk deepen bold complexity of bourbon-barreled (10.5% ABV) Belgian dark strong ale.
