Using a shaker, or a medium mason jar, add 4 fresh mint leaves and the pure maple syrup.
Using a muddler, or the handle of a wooden spoon, gently press down and twist on the mint leaves 3-4 times.
Next, add the fresh lime juice and a few ice cubes. Place the lid on the shaker, or mason jar, and shake vigorously 5-10 times to combine.
Pour mixture through a cocktail strainer, or tea strainer, into an 8 ounce rocks glass filled with crushed ice.
Top off with ginger beer.
Garnish with lime wedge and 1-2 mint leaves.
ENJOY!
