Cold Brew Coffee Tonic (Printable Version)

Chilled cold brew topped with tonic and orange zest for a bright, fizzy summer drink in minutes.

# What You'll Need:

→ Base

01 - 200 ml chilled cold brew coffee
02 - 200 ml chilled tonic water

→ Garnish

03 - Zest of 1 orange (plus an optional wedge)
04 - Ice cubes as needed

# How-To Steps:

01 - Fill two serving glasses with ice cubes to chill.
02 - Pour 100 ml chilled cold brew coffee into each glass.
03 - Gently pour 100 ml chilled tonic water over the cold brew in each glass to preserve effervescence.
04 - Stir each glass once or twice with a spoon to integrate coffee and tonic without flattening the bubbles.
05 - Express orange zest over the surface of each drink and drop the zest in; add an optional orange wedge to the rim.
06 - Present immediately while the drink remains cold and effervescent.

# Expert Advice:

01 -
  • No fancy equipment needed—just your favorite cold brew, tonic, and an orange.
  • Every sip feels like summer in a glass, and you can tweak sweetness or zest as you wish.
02 -
  • Stirring too fast or too vigorously flattens the tonic—gentle is key for those sparkling bubbles.
  • Freshly zested orange is a must; pre-zested or bottled zest just doesn’t give the same vivid aroma.
03 -
  • Avoid crushed ice—large cubes melt slower and keep things from watering down too quickly.
  • Trying with different citrus (like grapefruit or lime) can totally shift the mood of the drink.
