Fill a tall glass with ice.
Pour in 180 mL of cold tonic water.
Pour 90 mL of concentrate slowly over the back of a spoon so it lands on top.
Add an orange wheel if you have one. Drink it right away, while the tonic still fizzes.
Two liquids and ice, so the real work is brewing the concentrate. Tonic goes in first, concentrate on top.
Concentrate to tonic is 1:2, the same dilution the calculator defaults to for plain cold brew. One batch of concentrate makes four of these with some left over.
