Grappa hand detergent. The first grappa sanitizing hand gel detergent. Packaged in an elegant glass bottle, pocket/travel size, its practical spray top allows you to dose the correct amount onto your hands. Rub onto your hands until completely dry. This simple action, which by now has become natural and certainly essential for everyone's health, recalls an old tradition in which distillers rubbed grappa onto the back of their hands, to evaluate the quality and freshness of the original pomace based on the aroma of the grappa.
