Is sour mix the same as sweet & sour mix?

Sour mix is typically made by combining equal parts lemon and/or lime juice with simple syrup. The lemon and lime juice provide the sour taste, while the simple syrup adds sweetness. This mixture is then shaken vigorously with ice to create a well-blended mixer. The resulting sour mix is yellow-green in color and has a refreshing and tangy flavor.
