A team of researchers from the University of Minho (UM) could distill a drink from the coffee, but rather what happens to the liquor, did not use the grain: the drink is made with coffee grounds. Still, the alcohol content is so strong that equals the brandy or vodka.
process based on adding sugar and yeast (for catalyzing the fermentation), then leached with water to the dried coffee residues were boiled. The simplicity of this technique, already patented, guarantees a “high-value” to the new drink as highlights UM in a statement.
“In a production format in industrial context, although the process is relatively simple and inexpensive, the collection of large quantities of coffee grounds requires a system with some care, since these residues are moisture and other factors easy contamination “explained the researcher Solange Mussatto.
The main advantage of this distillation is the best use of coffee. “The sludge is about 80 percent of the grain,” said the scientist, the waste is “very rich,” he added, “the new beverage was identified as alcoholic coffee, but it is actually a distilled spirits as a transparent with 40 percent ethanol and coffee aroma. “
For Time magazine, the new drink ‘made in’ A is one of the 25 best inventions of 2013.
