Espresso martinis are two of our favorite things: intense coffee flavor and expertly crafted cocktails. With Jess and John Feller's infusion kit, you'll have just about everything you need to craft this sumptuous sip at home. The glass steeping jar comes prestocked with espresso beans, cacao nibs, and cinnamon. Just pour in the spirit of your choice (Jess and John recommend vodka, tequila, or whiskey) and wait about a week. The ingredients will steep into an aromatic liqueur that you can enjoy on its own or as the velvety base to a variety of coffee-flavored cocktails. The kit comes with complete instructions and two luscious recipes to get you started on your way to caffeinated cocktail bliss. Made in Chicago, Illinois.
