Add agave, water, and quartered peaches to a pot and place on high heat until boiling. Lower heat to medium and allow the mixture to simmer (approx 15 minutes).

Squeeze lemons until there is one cup of juice.

Remove peach mixture from heat. Strain liquid into pitcher, discard peaches.

Add lemon juice to pitcher.

Fill pitcher with desired amount of water. I suggest six cups. Add ice.

For extra flair, freeze fresh peach slices to use as garnish when serving.
