London Essence’s range of exquisite mixers are distilled from real botanicals for the purest flavour in every sip. This beautifully distinctive tonic water is flavoured with a creative blend of zesty cold-pressed grapefruit oils and distilled essence of rosemary. Finished with a touch of bitter quinine, this low-calorie tonic is strikingly flavourful and aromatic, an invigorating tonic for your favourite gins. Also available in a case of 24. Perfect Serve - This perfectly balanced blend of citrus and herbal notes blends brilliantly with citrus-led or citrus-flavoured gins for a summery G&T. We recommend Silent Pool’s Rare Citrus gin.
