Cold Brew Tonic: Step by Step Guide

Start by making a batch of cold brew coffee. Combine coffee grounds (Samba Nights is a crowd favourite) and cold water in your One Brew and let it steep in the refrigerator for 12-24 hours.


Once the cold brew is ready, fill a glass with ice.


Pour the cold brew over the ice, leaving about an inch of space at the top.


Top the glass off with tonic water.


Give the drink a quick stir and enjoy!

What is Cold Brew Tonic?

Cold brew tonic is a combination of cold brew coffee and tonic water, which creates a refreshing and fizzy drink that's perfect for summer. The cold brew is made by steeping coffee grounds in cold water for an extended period of time, which results in a smooth and less acidic coffee. Tonic water, on the other hand, is a carbonated soft drink that has a slightly bitter taste due to the addition of quinine.


The combination of these two ingredients creates a unique taste that's both refreshing and satisfying. Plus, the carbonation from the tonic water adds a fun and fizzy twist to your usual cold brew coffee.

Tips for Making the Perfect Cold Brew Tonic 

⭐ Use a light roast coffee to avoid overpowering the tonic water.


⭐ For a sweeter drink, add a splash of simple syrup or flavored syrup to the cold brew before adding the tonic water.


⭐ Experiment with different types of tonic water to find your favourite brand and flavour.


⭐ Garnish the drink with a wedge of lemon or lime for an extra burst of citrus flavour.
