Use 1/4 of a lime wedge to rub along the rim of your cocktail glasses. Pour the sugar on a plate and cover the lime rubbed rim with the sugar. Let it set by placing it to the side (still upside down in the sugar)
Peel and roughly chop your peaches. Add the chopped peaches and mint leaves to a pitcher.
Squeeze the juice out of your limes into the pitcher. If you prefer more lime taste use 3 limes instead of 2.
Use a spoon or whisk to muddle the peaches and mint in the lime juice in the pitcher. The more you crush/muddle the ingredients the stronger the flavors will be in your drink.
After you've muddled the ingredients pour the bottles of ginger beer into the pitcher. Let it sit until the fizz from the carbonation settles.
Add your desired amount of white rum to the mixture. Gently stir until all the flavors are well combined.
Put a handful of ice cubes in your sugar rimmed glasses and pour your mojito over the cubes. Swirl and enjoy!
