On tap at Ambulance, fantastic St. Patrick’s Day Celebrator aged in whiskey barrels with cold-brewed coffee and Madagascar vanilla beans penetrates deeply with its smoothly creamed Irish coffee warmth. Spiced black chocolate, caramel latte, hazelnut crème, dark toffee and crème brulee illusions elevate luxurious whiskeyed coffee prominence above teasing hop-charred bitterness. Elegance personified by newly minted Mamaroneck brewer.
