In a pint glass, add sugar, water, lime juice, and Pisco together. Stir for a minute to help the sugar dissolve. Add orange juice and stir together. Add club soda and Red Bull and stir very gently. If you stir to intensely, the fizz will go away.

Fill two short cocktail glasses with crushed ice. Split the cocktail between both glasses. Slice two thin slices of orange peel. Take one peel and rub the outside (orange side) around the rim of the glass. Repeat with other glass. Place peels in each respective glass as a garnish and serve.
