To make the simple syrup, pour water and sugar into a small pot and let it come to a boil. Stir until sugar dissolves. Take off the heat and let cool.

Add ice to the glass and pour whiskey.

Pour in ½ ounce Manila Gold Calamansi simple syrup.

Fill the rest of the glass with ice tea.

Garnish with mint leaves and/or fresh sliced calamansi.

Serve immediately and enjoy!
