A brilliantly refreshing mixer, Schweppes Slimline Bitter Lemon is a sparkling soft drink with sharp citrus and the perfect bubbly finish. Though Schweppes have been producing premium blends for over 200 years, their Bitter Lemon Tonic was released as recently as 1957. Since then, it’s become a staple for master mixologists and casual drinkers alike thanks to its refined palate of quinine and fresh, floral lemon zest. If you fancy stocking up on this essential mixer, Bitter Lemon is also available in a case of 24. Perfect Serve – For a more sophisticated take on a Vodka Lemonade, mix this 20cl bottle of Schweppes Bitter Lemon with a double shot of premium vodka.
