As an expert sommelier and brewer, I can confidently say that there is no right or wrong answer when it comes to enjoying whisky on ice. It ultimately comes down to personal preference and how you want to experience your whisky.
There is a longstanding debate among whisky enthusiasts about whether or not it is acceptable to add ice to single malt scotch. Some purists argue that adding ice dilutes the whisky and mutes its flavors and aromas. They believe that whisky should be enjoyed neat, without any dilution.
On the other hand, there are those who argue that adding ice to whisky can actually enhance the drinking experience. By chilling the whisky slightly, the flavors may become more subdued, allowing for a smoother and more approachable taste. The melting ice also adds a small amount of water to the whisky, which can help to open up the flavors and aromas, making them more pronounced.
Personally, I believe that there is no harm in adding a cube or two of ice to your whisky if that's how you enjoy it. I have found that the slight chill from the ice can be refreshing and can make the whisky more enjoyable, especially on a hot summer day. The melting ice also has the benefit of slowly releasing the flavors and aromas, allowing you to fully appreciate the complexity of the whisky.
I have had the opportunity to taste many different whiskies both neat and on ice, and I can say that there are merits to both methods of consumption. It really comes down to personal preference and how you want to experience your whisky. If you prefer a more intense and robust flavor, then drinking it neat may be the way to go. However, if you enjoy a smoother and more refreshing taste, then adding ice can be a great option.
In the end, whisky is meant to be enjoyed and savored. Whether you choose to drink it neat, on the rocks, or even in a cocktail, the most important thing is that you are enjoying the flavors and aromas that the whisky has to offer. So go ahead and have your whisky on ice if that's what you prefer, and savor every sip. Cheers!
