What is Cold Brew Coffee Tonic?

Cold brew coffee tonic is a non-alcoholic coffee mocktail that combines cold brew coffee concentrate with tonic water, a fizzy, caffeinated drink. Tonic and coffee might seem weird together, but it’s a combo that’s taken off in the specialty coffee world and gives drinkers looking for something other than a regular cup of coffee or espresso a refreshing kick.
This iced coffee alternative has become super popular as cafes and home baristas discover its awesomeness. The drink’s signature is the contrast between the rich, bitter coffee and the bright, slightly bitter carbonation of the tonic water, creating depth and complexity that’s surprising and fun.

Making Cold Brew Concentrate
- Combine coffee and water: In a large jar or cold brew maker, mix coarsely ground coffee with cold filtered water at a 1:4 ratio.
- Steep: Refrigerate the mixture for 12-24 hours. The longer steeping time creates a more concentrated, smoother flavor profile.
- Strain: Filter the mixture through a fine-mesh strainer lined with cheesecloth or use a cold brew maker’s built-in filter. Store concentrate in the refrigerator for up to two weeks.
Assembling Your Cold Brew Tonic
- Prepare the glass: Fill a tall glass with ice cubes, leaving space for the liquids.
- Add cold brew: Pour ¼ cup of cold brew concentrate over the ice. Try 1 part cold brew to 2 or 3 parts tonic for a cold brew tonic.
- Top with tonic: Slowly pour ¾ cup of chilled tonic water to preserve carbonation and create natural layering.
- Garnish and serve: Add a lime or lemon wedge, give it a gentle stir, and serve immediately.
Benefits of Cold Brew Coffee and Tonic Water
Cold Brew Benefits
Cold brew coffee has several advantages over hot brewed coffee. The longer cold brew process makes a naturally sweeter, less acidic coffee that’s easier on the stomach. This method also retains more of the coffee’s natural antioxidants and gives sustained energy without the jitters of hot coffee.
The concentrate format makes cold brew super convenient for coffee tonic variations as it maintains flavor strength and can be made ahead of time. The smooth, mellow flavor is the perfect base for the bright, bitter of tonic water.
Tonic Water’s Part
Good quality tonic water brings the important stuff to this fizzy coffee drink. The carbonation adds texture and lifts the coffee’s aromatics while the quinine adds a bitter note that complements the coffee’s natural bitterness. It’s a layered flavor experience that’s more interesting than either ingredient on its own.
Creative Variations and Customizations
Flavor Additions
Citrus: Add fresh orange or grapefruit juice for a bright, acidic boost to both coffee and tonic.
Spiced: Add cardamom, cinnamon or vanilla simple syrup for warm spice.
Herbal: Muddle fresh mint or basil leaves for a garden-fresh twist.
Strength Adjustments
- More Coffee: ⅓ cup cold brew concentrate, ⅔ cup tonic
- Less Coffee: 3 tablespoons concentrate, 1 cup tonic
- Sweet: 1-2 teaspoons simple syrup or flavored syrup
Seasonal Variations
Summer: Add fresh berry muddled fruits or coconut water for tropical vibes Fall: Pumpkin spice syrup or maple syrup Winter: Nutmeg or allspice

Tips for the Perfect Cold Brew Tonic
Quality Matters
Use high quality coffee beans and premium tonic water. Since this recipe is so simple, each ingredient’s quality will shine through. Choose coffee beans with flavor notes that complement tonic’s botanicals – Ethiopian or Colombian beans work really well.
Temperature and Timing
Make sure both the cold brew concentrate and tonic water are chilled before mixing. Room temperature ingredients will dilute the ice too fast and result in a flat, watery drink. Serve immediately after making to keep the carbonation.
Experimentation Encouraged
Don’t be afraid to adjust the ratios to your taste. Some like a stronger coffee presence, others like the lighter, more refreshing version with more tonic. Start with the basic recipe and adjust to your palate.
Coffee Tonics are Here to Stay
Americans think it’s new and novel, but so was the espresso martini at one time! The coffee tonic trend is part of a bigger movement towards creative, non-alcoholic drinks that offer complexity and sophistication without the booze.
It’s grown in Scandinavia, Europe and America and is a surprise alternative to iced coffee. First came to the UK via Soho, the espresso tonic spread through festivals and independent cafes and is now in high street chains
This growth means coffee and tonic water combinations are more than just a trend – they’re a legitimate evolution in coffee culture for adventurous drinkers looking for new experiences.
