To a pitcher add bourbon, pear juice, lemon juice, maple syrup, and orange bitters.
If using, dilute pitcher with ½ cup filtered water.
Mix together and place in the fridge until ready to serve.
When ready to serve either a) pour the diluted mix over a cube or b) if you didn’t dilute, add the mix to a cocktail shaker filled with ice to shake and strain into glasses with an ice cube.
Top each glass with 2 oz. of Champagne and garnish!
