Wash four fresh limes thoroughly under cold water. Cut each lime into wedges, removing the ends.

In a blender, combine the lime wedges, two cups of water, one cup of coconut milk, and a quarter cup of maple syrup. Blend on high for about 30 seconds.

Strain the blended mixture using a fine mesh strainer over a large pitcher, pressing down gently on the solids.

Fill glasses with ice cubes or crushed ice and pour the limeade over the ice.

Garnish with a lime wheel on the rim of each glass and serve immediately.
