When we talk about the identification of fraudulent foods and beverages, many elaborate methods are available in analytical chemistry and food labs. The method of using “whiskey webs” is quite unusual in its simplicity; it is based on the unique residue left behind by each beverage after evaporation. American Whiskey is matured in new charred oak barrels that transfer a number of water-insoluble components into the final product, allowing each whiskey to leave behind its own unique “fingerprint”.
