  • 1 cup peeled and diced cucumbers
  • 1/2 cup fresh mint leaves, finely chopped
  • 1 cup sugar
  • 1 cup filtered water, does not have to be cold - the water will be boiled for the simple syrup
  • 1/2 - 1 tablespoon Green Bean coffee powder, optional
  • 1 1/2 cups Fresh lime juice, (about 10 limes yields one cup of lime juice, 1 1/2 cups = 15 limes)
  • 2 cups white grape juice
  • 5 cups cold filtered water, divided


  1. Add 1 cup of peeled and diced cucumbers and 1/2 cup of finely chopped mint leaves into 3 cups of the cold filtered water. Store in a lidded container and place in the fridge (a minimum of 2 hours but this can be done up to 24 hours ahead of time- the longer the water mixes with the cucumber and mint, the better.)

  2. Add 1 cup of sugar (or sugar substitute) to the 1 cup of filtered water (does not have to be cold) to create a simple syrup. Heat and stir until the sugar is dissolved. Add the green bean coffee powder and stir. Remove from heat and let cool.
  3. Drain the cucumber/mint water over a strainer, saving the water. (The cucumber/mint mixture can be discarded or used as a garnish.) Add the cucumber/mint water into a large pitcher, add the simple syrup and the juice of about 15 limes**
  4. Add the white grape juice and the remaining 2 cups of the cold filtered water and stir well. Serve immediately over ice or let the mixture sit in the fridge so the flavors all mix.

Recipe Notes

*I have a hard time finding the Green Coffee Bean powder in anything other than capsule form, so I have bought a bottle and used the powder from inside the capsules.
**You can also cheat and use bottled lime juice. 2 tablespoons of the bottled stuff yields the juice of one medium sized lime. However, be very careful not to buy lime juice from concentrate as it will be very, very strong. Trust me on that one.
