Researchers from the University of Minho in Portugal have been messing around with two of our favorite vices: coffee and alcohol. Now they have found a way to combine the two into an 80-proof liquor that still has the nutty aroma of coffee. Unlike a mixed coffee drink like Irish coffee, this dual-shot beverage is actually fermented from the coffee beans themselves.

And yes, in case you were wondering, you can try it at home. According to Science Magazine, you’ll first need to heat coffee grounds in water at 325 degrees Fahrenheit to collect the resulting liquid. From there, you add sugar as well as yeast to begin the fermenting process, which you allow to run its course until the brew reaches around 40 percent alcohol content.

The one downside of this product is it destroys the caffeine in the coffee, so you won’t be able to get buzzed and caffeinated at the same time. (If you could, the FDA would probably want to have a word with you.)

The eight testers who tried the concoction called it a pleasant beverage that tastes just like coffee, but with a bitter, pungent kick to it. But like all booze, the alcoholic mud could be altered and improved with a little bit more age and tweaked into something truly great. Drink—and brew—responsibly.
