A split-vermouth cousin of the Rob Roy, the Affinity stirs Scotch whisky together with equal measures of dry and sweet vermouth, the two fortified wines bridging the malt's smoke and the drink's name nodding to their easy chemistry. Two dashes of Angostura and an expressed lemon peel keep it bright and aromatic. Documented across early-1900s bartending books and an IBA official cocktail from 1961, it's a balanced, spirit-forward classic that predates and parallels the Rob Roy.
