This is what tonic water wishes it were. Premium Tonic is built around real quinine for that crisp, classically bitter tonic backbone — then layered with lemon puree, jasmine, elderflower, and grapefruit peel for a floral, citrus-forward complexity you don't get from a can. Mix one part syrup with six parts sparkling water and you've made craft tonic from scratch in less time than it takes to pop a Schweppes.

It's the secret weapon behind a gin and tonic that actually tastes like a cocktail. Pour 1 oz over ice with 1.5 oz of gin, top with sparkling water, and you'll wonder why you ever drank tonic from a can. Stir it into vodka for a clean, dry, citrus-floral mixer. Mix it solo with sparkling water for a sophisticated zero-proof spritz that holds its own at any dinner party. Bonus: one bottle makes about a gallon of tonic, which means no more flat tonic water at the back of your fridge.

Tasting Notes: bright lemon, soft jasmine and elderflower, grapefruit peel zest, classic quinine bitterness

Frequently Asked Questions

Q: How long does the syrup last after opening?
A: Our syrups are shelf-stable for 24 months unopened. Once opened, refrigerate and enjoy within 6 months.

Q: What's the difference between Premium Tonic and Grapefruit Tonic?
A: They're built around different flavor profiles. Grapefruit Tonic leads with bright pink grapefruit and elderflower for a fruit-forward, slightly tropical take on tonic. Premium Tonic is more refined and floral — built around real quinine, with lemon, jasmine, elderflower, and grapefruit peel layered in for a classic dry tonic profile. If you want something that drinks like a craft grapefruit soda you can also turn into a cocktail, choose Grapefruit Tonic. If you want a traditional, bitter-bright tonic-water replacement for a proper gin and tonic, choose Premium Tonic.

Q: Can I use Premium Tonic syrup as a substitute for tonic water?
A: That's actually one of its primary uses. Mix 1 oz of syrup with 6 oz of sparkling water and you've made craft tonic water from scratch — significantly more flavorful than anything canned, and it doesn't go flat in the fridge. One 12 oz bottle makes about a gallon of finished tonic, which is roughly 8 cans of Schweppes worth, at about half the price.
