Roots Divino Rosso is an alcohol-free vermouth made on the island of Lesvos, Greece, from a fermented grape concentrate base. The brand positions it as a wine-based product, distinguishing it from AF vermouths built on spirit-distillate bases. The alcohol is removed by reverse osmosis, a filtration method that separates alcohol using membranes. The botanical selection draws on bitter orange, gentian and wormwood, giving the drink its bitter-herbal character.
