Sometimes you want a cocktail that drives you nuts. With flavor, that is. And, you're in luck, because falernum syrup does just the trick! Not only can you use this staple ingredient in your cocktails, but you can add this to your morning coffee to give it a little extra buzz. Or your espresso martini. Whatever floats your falernum syrup boat.

What Is Falernum Syrup?

Falernum syrup isn't new to the cocktail scene, not by a long shot. You'd need to travel as far back as the 1700s to Barbados to find its roots. However, there's a pretty good chance that the 18th century falernum isn't the falernum you know and love in the 21st century. Today's spicy almond didn't pop up until the 1930s. This citrus, spice, and almond ingredient gives cocktails a tropical spin with the perfect touch of flavor.
