The Old Fashioned ­is an iconic drink, but few understand the complexity of its components. In this three-part video series, expert craftsmen break down its three key ingredients ­— the bitters, the sweetener, and the ice ­— to demonstrate how each part, when paired with a quality spirit like Knob Creek^®, contributes to this classic cocktail. This is: The Anatomy of an Old Fashioned.

An afterthought to many drinkers, the shape and size of ice is actually an essential detail in developing the flavors of a cocktail. Depending on what a bartender is trying the achieve, the size and shape chosen — which dictates whether it will chill or dilute the alcohol — will greatly affect the drink. For an Old Fashioned, meant to be sipped and enjoyed over a longer period of time, bartender Henry Jakstas finds a large piece of ice is key: it facilitates the proper dilution needed to let the bold flavors of Knob Creek^® Single Barrel Reserve shine.
