- 1-2 oz. cold brew concentrate, or 4 oz. nice cold brew coffee
- 1 slice lime
- handful ice
- top quality ginger ale/beer (Trader Joe’s is nice for those in the US)
Place the slice of lime in a highball glass and muddle it. Add a handful of ice and the coffee. Fill the rest of the glass with the ginger ale.
