Each bottle of Ruta features a large sprig of rue, a bitter herb that gives this unusual grappa a delightfully astringent flavour. Although the infusion is an acquired taste for some, Ruta has many advocates & was always the personal favourite of Aldo Signetti, the legendary head barman at Dukes Hotel in St James. In homeopathy, rue is sometimes used as a fever suppressant, but according to Italian folk-lore it not only increases male potency but assists women to relax. A fairly useful combination.
