Yes. You can use any whiskey or bourbon that you prefer. That can be rye or wheat whiskey or bourbon. Irish or American, it is all about your preference. The whiskey you use will have a specific taste in this whiskey cocktail recipe. My recommendation is to choose a smooth whiskey which is usually a lower proof. High-proof whiskeys can taste and feel “hot” or burn in your mouth. A few moderately priced whiskeys that tend to be smooth include: Bulleit - Rye or bourbon Buffalo Trace Bourbon Maker’s Mark Bourbon
