What is the term for a drink created by mixing various spirits and juice, typically shaken?

The correct term for a drink created by mixing various spirits and juice, typically shaken, is indeed a cocktail. Cocktails are defined by their combination of different ingredients, which often include multiple types of spirits, juices, and additional flavorings. The process of shaking is essential for cocktails as it helps to mix the ingredients thoroughly and chill the drink, enhancing its texture and flavor profile.

In contrast, a highball is typically a simpler drink consisting of a spirit and a larger proportion of a non-alcoholic mixer, served over ice. A sour refers specifically to a cocktail that typically includes a base spirit, sugar, and lemon or lime juice, which creates a distinct tart flavor. Finally, a fizz usually involves a spirit and citrus juice with the addition of carbonated water, leading to a bubbly texture, but does not encompass the broader category of a drink simply mixed and shaken. This specificity helps clarify why cocktail is the most accurate term in this context.
