Mix the whiskey, lemon juice, and simple syrup in a cocktail shaker without ice. If you're using the egg white, add it in now. Shake for no longer than 15 seconds.
Add ice to the shaker and give it another good shake.
Strain into a rocks glass filled with a few ice cubes. Then top it off with the red wine poured over the back of a barspoon just above your cocktail's surface.
