Does adding a few drops of water ruin a bourbon?
Short answer: No; for most bourbons, especially higher-proof ones, it does the opposite.
A small amount of water doesn't just dilute a whiskey; it changes how it releases aroma. Many of the compounds responsible for a whiskey's smell and flavor cling to the alcohol at high concentration; adding a little water frees them up to evaporate and reach your nose, which is why professional judges and master blenders routinely add water when formally evaluating a spirit, especially a cask-strength one.
That doesn't mean water is mandatory or that drinking it neat is wrong; it's a matter of what a given whiskey, and your own palate, responds to. A 90-proof bourbon may not need it at all; a 130-proof barrel-proof pour often opens up noticeably with just a few drops.
Practical Takeaway
Try a pour neat first, then add a few drops of water and taste again before deciding; you're not obligated to do either, but writing off water entirely means missing what a lot of experienced tasters treat as a normal part of evaluating a whiskey.
