Fill a pitcher with 6 cups of water.

In a small bowl, use your fingers to toss together mint and limes, working the mint leaves to gently release some of their oils and flavor.

Stir limes and mint into the water. Refrigerate for 10 minutes, or up to 2 days for the flavors to infuse into the water. The longer you let it chill, the stronger the water will taste.

Serve with ice, if desired.
