I was sent this cocktail recipe to celebrate "Bourbon Heritage Month" (September, apparently) but I see no reason to limit it to a specific part of the year. It has the fresh winter citrus of lemon and grapefruit, spicy ginger liqueur, and a bourbon whiskey that's good any time.
For a lighter version of the drink, you can substitute fresh ginger syrup for the ginger liqueur. I don't quite have the recipe's recommended garnish figured out, but feel free to throw a couple of slices of fresh ginger into the shaker to give it some extra spice.
It should make a cool drink for a hot summer days, or a spicy drink for chilly fall nights. Either way, you win.
