Portuguese and Spanish researchers writing in the journal LWT—Food Science and Technology announced the birth of a new coffee-based beverage. They dried used grounds, heated the powder in scalding water for 45 minutes, removed the liquid and added sugar and yeast. Then they let the mixture ferment and concentrated it to boost the alcohol content. The result? A booze that’s about 80 proof, like tequila and vodka. It’s good enough to consume, they found, and its taste might improve with age. But beware: this coffee won’t keep you awake, since most of the caffeine disappears as it brews.
