Roots Divino Bianco is an alcohol-free vermouth made on the island of Lesvos, Greece, from a base of fermented grape concentrate. The alcohol is removed by reverse osmosis, a filtration method that separates alcohol from liquid using membranes, leaving the botanical character intact. The botanical selection, rosemary, thyme, wormwood, lemon and gentian, is macerated in the traditional vermouth manner. The brand positions this as the first wine-based zero-proof vermouth in the category, tracing its concept to the ancient medicinal wine tradition associated with Hippocrates.
