Caipiroska is a variation of the classic Caipirinha cocktail, but instead of cachaça, it is made with vodka. It is a popular choice for those who prefer a lighter and less sweet drink. Caipiroska is made by muddling lime and sugar together, adding vodka and ice, and then shaking it well. The result is a refreshing and citrusy cocktail that is perfect for a night out in Rio's vibrant nightlife scene.
