Whiskey Sour is typically made with bourbon, not scotch. While both scotch and bourbon are types of whiskey, they have distinct differences in terms of ingredients, production methods, and flavor profiles.
Bourbon is an American whiskey that is primarily made from corn. It must be aged in new charred oak barrels and distilled to no more than 160 proof (80% alcohol by volume). The use of corn gives bourbon a sweeter and smoother flavor profile, often with notes of vanilla, caramel, and oak. This sweetness complements the tartness of the lemon juice in a Whiskey Sour, creating a balanced and refreshing cocktail.
On the other hand, scotch whisky is made in Scotland and is typically made from malted barley. It is aged in used oak barrels, which imparts different flavors compared to bourbon. Scotch whisky often has a more complex and smoky flavor profile, with hints of peat, fruit, and spice. While scotch can be used in cocktail recipes, it is not the traditional choice for a Whiskey Sour.
When it comes to making a classic Whiskey Sour, the choice of bourbon is crucial. The 80-proof bourbon is recommended as it strikes a balance between the sweet and sour elements of the cocktail. Higher proof bourbons may overpower the other ingredients, while lower proof ones may not provide enough flavor. Of course, personal preference plays a role, and some people may prefer a specific bourbon brand or proof for their Whiskey Sour.
In terms of personal experiences, I have tried making Whiskey Sours with both bourbon and scotch. While the scotch version had its own unique flavor profile, it didn’t quite capture the classic balance and harmony that bourbon brings to the cocktail. The sweetness of the bourbon complements the tartness of the lemon juice in a way that scotch doesn’t quite achieve.
To summarize, a Whiskey Sour is typically made with bourbon, not scotch. Bourbon’s sweeter and smoother flavor profile pairs well with the tartness of the lemon juice, creating a balanced and enjoyable cocktail. While scotch can be used in cocktails, it is not the traditional choice for a classic Whiskey Sour.
