The Porto Caipirinha is a refreshing and fruity cocktail that combines the flavors of Porto wine, lime, and sugar. It is made by muddling lime wedges with sugar in a glass, then adding Porto wine and ice. The mixture is stirred gently and garnished with a lime wheel. The Porto Caipirinha has a tangy and slightly sweet flavor, with a refreshing citrus kick from the lime. It is a perfect choice for a hot summer day or a tropical-themed party.
