Cinnamon sour cocktail is a delightful and aromatic drink made with bourbon, lemon juice, simple syrup, and a touch of cinnamon. It is a perfect cocktail for fall or winter, with warm flavors and a hint of spice. The bourbon adds a rich and smoky note, while the lemon juice provides a refreshing tartness. Serve it over ice and garnish with a cinnamon stick for a festive touch.
