A sassy drink with a little bite! Low in calories, high in vitamin C, loaded with electrolytes, potassium and   bioflavonoids, grapefruit juice is a delicious and nutritious addition to healthier cocktails. The spicy addition of a Serrano or Jalapeño slices add the health benefitting alkaloid compound, capsaicin. Capsaicin has antibacterial, anti-carcinogenic, analgesic and anti-diabetic properties. This simple cocktail is refreshing and complex, making it the perfect all season sipper.
