Dubonnet is a fortified and aromatized wine, and it also comes in a Blanc version (with a green label). But while Lillet Blanc is the more popular version of that spirit, the red red Rouge is the more popular version of Dubonnet. On its own (and on the rocks), Dubonnet immediately strikes you with the taste of Port wine, a raisiny concoction with a distinctly herbal, bittersweet aftertaste. It's not at all bad (and easily better that Lillet Rouge on its own).
