The Passionfruit Martini is part of Sir James 101's range of non-alcoholic ready-to-drink cocktails, each modelled on a recognised bar format. The brand developed the range in response to what they saw as a market dominated by overly sweet, lemonade-like mocktails, and this expression was specifically designed to replicate the foam layer and visual presentation of a freshly shaken cocktail. The flavour is structured around passionfruit and vanilla, with a deliberate bitterness on the finish intended to echo the complexity of a vodka-based original. Sir James 101 is produced by P.M. Spirits, a family-owned company with a background in traditional spirit production, which the brand says informed the recipe development approach.
