Bourbon Lemonade with Maple Syrup

I've had this at two different parties now since seeing it on Smitten Kitchen. The recipe below is doubled to make a full pitcher. This recipe also works well with Jack Daniels if you want to pass on the more expensive bourbon.

Bourbon Lemonade with Maple Syrup (from Smitten Kitchen)

Ingredients
2 cups freshly squeezed lemon juice (14 - 16 lemons)
5 cups cold water, plus additional if needed
1 cup maple syrup
Bourbon (or Jack)
Lots of ice

1. Mix lemon juice with 5 cups water and 1 cup maple syrup.
2. Fill a glass with ice. Pour 1 to 1 1/2 shots of bourbon over the ice and fill the glass the rest of the way with maple lemonade.
