The Hugo is a refreshing cocktail that originated in the South Tyrol region of Italy but has become popular in Venice. It is made with Prosecco, elderflower syrup, fresh mint leaves, and a splash of soda water. The cocktail is typically served over ice in a wine glass and garnished with a sprig of mint and a slice of lime. The Hugo has a floral and citrusy flavor profile, making it a perfect choice for a summer cocktail.
