Gunner Original Ginger Bitters & Lime is a non-alcoholic ready-to-drink adaptation of the Gunner, a mixed drink attributed to Ewen Fergusson and Robert Renton at the Singapore Golf Club. The original recipe found an audience in clubs across Singapore, Hong Kong, and India during the colonial era, before the format faded from widespread availability. The brand's version uses natural bitters containing quinine alongside lemon and grape juice concentrates and apple extract, giving it a complexity beyond a standard ginger beer or lemonade blend. It is now made in the UK.
