Combine the beer and syrup in a pilsner glass.
*Demi peche syrup: Peel, pit and slice 4 ripe peaches and lightly salt with a pinch of kosher salt. Heat in a saucepan over medium high heat, allowing peaches to lightly caramelize. Add 2 cups refined sugar and 2 cups water and stir. Bring to a simmer, stirring frequently, for 2 minutes, remove from heat, and allow to cool to room temperature. Strain (preferably through a cheesecloth) and refrigerate.
