From the producer:
"Super simple, but super specific makes Mario’s Crazy Delicious.
We handcraft every bottle of Mario’s Hard Espresso starting with Triple-Distilled, 200-proof Grain Neutral Spirit. It’s pure and super smooth and imparts no alcohol flavor, like what happens in other coffee liqueurs made with a lower proof vodka, tequila or rum. This allows the rich, delicious flavors of the 100% Arabica Dark Roast Italian Espresso, Organic Madagascar Vanilla and a touch of Cane Sugar to blend beautifully and really come through. It’s also what makes Mario’s so incredibly versatile as a delicious addition to traditional cocktails made with whiskey, bourbon, rum, mezcal, vodka and tequila. Cheers!"
