Cold Brew Coffee Tonic (Printable)

Effervescent cold brew with tonic and orange zest for a bright, sparkling summer sip.

# Ingredient List:

→ Base

01 - 6.76 fl oz (about 200 ml) cold brew coffee, chilled
02 - 6.76 fl oz (about 200 ml) tonic water, chilled

→ Garnish

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

# How to Make:

01 - Fill two tall glasses with a generous amount of ice to chill the vessel and maintain effervescence.
02 - Divide the cold brew evenly, pouring approximately 3.38 fl oz (about 100 ml) into each glass over the ice.
03 - Gently pour about 3.38 fl oz (about 100 ml) chilled tonic water into each glass, aiming to preserve carbonation by pouring slowly down the side.
04 - Using a long spoon, stir each drink once or twice with a gentle lift-and-fold motion to integrate without flattening the tonic.
05 - Express the orange zest over each glass to release oils, drop the zest in, and add an optional orange wedge on the rim.
06 - Serve immediately while the tonic is still effervescent to retain the bright contrast between coffee and citrus.

# Expert Tips:

01 -
  • It feels like your own secret signature drink—but takes less than five minutes from start to finish.
  • The combo of cold brew and tonic water is impossibly refreshing and guaranteed to wake up your tastebuds.
02 -
  • Once, I rushed and dumped the tonic in too fast—the bubbles overflowed and I lost a third of my drink. Patience is key.
  • Switching to a floral tonic water completely changed the flavor, adding a delicate finish that I now always look for.
03 -
  • Avoid stirring too vigorously after adding tonic to preserve the bubbles—it took me a few flat drinks to learn this.
  • Pouring the tonic down the side of the glass keeps the drink lively and sparkling to the last sip.
