Grand Marnier - or "GrandMa," as some cocktail geeks gleefully shorthand it - remains one of the classics. Although it's Cognac-based, it's a versatile match for other spirits, too. The liqueur is extremely aromatic, with lots of sweet and bitter orange notes exploding out of the glass. Look for a warm, honeyed flavor and a nice burst of orange peel and spicy cinnamon and ginger on the long finish. Tasting Notes Bright topaz with gold and amber tints. Complex nose of orange flowers combined with scents of candied zests and toffee. Bitter orange flavors are enhanced by the cognac with nuances of orange marmalade and hazelnuts. The finish is long and harmonious.
