Now you can get a new kind of buzz from coffee. Researchers have found a way to turn used coffee grounds into an alcoholic beverage. In recent years, the industry of distilled spirits has put out a call for new beverages with different flavors created from unusual raw materials. To answer this call, some scientists examined the potential of used coffee grounds. The scientists first collected this raw material from a Portuguese coffee roasting company and dried it. Then they heated the powder in water at 163°C for 45 minutes, separated out the liquid, and added sugar. Next, the team mixed in yeast cells, let the concoction ferment, and concentrated the sample to get a higher alcohol content. (A similar process is used to produce other distilled beverages such as whiskey and rum from wheat and molasses.) And voilà!
