The Seoul Mule is a refreshing cocktail that puts a Korean twist on the classic Moscow Mule. Made with soju, a popular Korean distilled spirit, ginger beer, lime juice, and a splash of simple syrup, this cocktail is both tangy and sweet. It is typically served in a copper mug with a garnish of fresh mint and a slice of lime. The Seoul Mule is the perfect drink to cool down on a hot summer day in Seoul.
