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

The Short Version: A floral, citrus-forward craft tonic concentrate built with real quinine — instant craft tonic for gin and tonics, vodka tonics, and sophisticated zero-proof spritzes.

Ingredients: Filtered water, organic cane sugar, lemon puree, jasmine, elderflower, grapefruit peel, quinine, citric acid.

Perfect For: Gin and tonic loyalists, craft cocktail enthusiasts, mocktail makers, dinner party hosts, and anyone who's gotten tired of canned tonic water that goes flat on day two.

Best Enjoyed In: Gin and tonics (1 oz syrup + 1.5 oz gin + 6 oz sparkling water), vodka tonics, premium tonic spritzes (1 oz + 6 oz sparkling water for a craft mocktail), or mezcal-tonic highballs for something a little more interesting.

The Portland Syrups Promise: Ethically sourced, carefully brewed, and bottled in glass jars right here in SE Portland, Oregon.

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.

I bought all three tonics together and this is the only one I really liked with gin. It's flavors are assertive enough to not be drowned out by it, but also not overpower it. Perfectly balanced and very, very good in just plain bubbly water as well.

I usually buy Fever Tree tonic for an occasional gin n tonic.. but now that I’ve tried these tonics., it’s my new go to! I love both of them! The Rose City and the classic! 🍹🥰🪻🌿♥️🪶

Nice surprise

Very rich taste. The root beer syrup was very adequate. Great

Top Notch Tonic

Bright, complex, flavor, that is refreshing alone or with a good gin or vodka. I love to play with the tonic concentration and amount of effervescence to personalize the mixer to my taste. This makes a perfect tonic water geared to just how you want it.

Tried many syrups to make tonic water using my soda stream. This brand beats the rest for great flavor at a reasonable price.

Some disappointment

The Tonic and Falernum w we're really great and I have been making lots of cocktails with them. Unfortunately the bottle of Grenadine was completely smashed and I was unable to try it.

Really good. We’d tried the rose tonic, but sometimes you want a straight tonic and this is way better than tonic water you buy at the store.

This is a great addition to my vodka tonics! So good!
