1. Add the whiskey, ginger syrup and lemon juice into a shaker with ice and shake until well-chilled.
2. Strain into a chilled coupe, and top with the beer.
3. Garnish with a lemon wedge.

*Ginger syrup: In a small saucepan, heat 1/2 cup fresh ginger juice (squeezed from freshly grated ginger root) until warm (but do not let boil) over low heat. Add 1 cup sugar, and whisk until sugar is dissolved. Store the syrup in a sealed container in the refrigerator until ready to use.
