From the maker:
A long-lost concoction crucial to drinks from the golden era of tropical cocktails. Passion fruit, cherries, and other flavors add a bit of zip to your libations, and unlock a treasure of drink recipes from long ago. Try some Red Fassionola syrup to enhance your hurricanes, to make an incredibly flavorful daiquiri, or just mix with soda water for a treat everyone can enjoy! Works great with Rum, Gin, and Vodka!
