Is it OK to put ice in bourbon?

As a sommelier and brewer, I have spent a lot of time exploring and understanding the complexities of various types of whiskey, including bourbon. The question of whether it is okay to put ice in bourbon is a topic that often sparks debate among whiskey enthusiasts. Traditionally, adding ice to whiskey has been seen as taboo, as it is believed to dull the flavors and aromas of the spirit. However, over time, I have come to appreciate that personal preference plays a significant role in how one enjoys their whiskey.

Bourbon, by law, is required to be aged in new charred oak barrels. This process imparts rich and intense oak flavors to the whiskey. When ice is added to bourbon, the cold temperature can enhance these oak flavors to the point where they become overpowering. This is especially true if the bourbon is already heavily oaked or has spent an extended period of time in the barrel. If you are someone who enjoys the strong presence of oak in your bourbon, then adding ice may be a suitable choice for you.

On the other hand, when it comes to Scotch whiskey, the rules are not as rigid as those for bourbon. Scotch can be aged in a variety of barrels, including used bourbon barrels, sherry casks, or even wine barrels. As a result, the flavor profiles of Scotch whiskies can vary greatly. Ice can often complement older Scotch whiskies by mellowing out any harsh or intense flavors that may have developed over time. However, I personally recommend adding a few drops of water instead of ice to Scotch. Water can open up the aromas and flavors of the whiskey without diluting it too much.

It is important to note that taste is subjective, and what one person enjoys may not be the same for another. If you prefer the way ice affects the flavors of your bourbon or Scotch, then by all means, go ahead and add it. Whiskey is meant to be enjoyed, and there are no hard and fast rules when it comes to personal preference.
