This is why most professional whisky tasters add water. A few drops can lower the ABV to a "release point" (often between 35-45%) where the flavor compounds are no longer locked in by the alcohol matrix and become more volatile, releasing their aroma.
So, a 40% ABV whisky is already pre-diluted to a drinkable, flavorful strength. A 55% ABV cask-strength whisky has the potential to be more flavorful, but only if you add water to unlock it. percentage of alcohol in whisky
False. Distillers who release cask-strength whisky fully expect you to add water. In fact, they design the whisky to be diluted by the drinker to their personal preference. Not adding water to a 65% ABV whisky is like eating raw pasta—you’re missing the intended preparation. This is why most professional whisky tasters add water
This leads to a critical concept. Many whiskies bottled at 40-43% ABV are . When you dilute whisky below about 46% ABV, the fatty acids and esters (which are delicious) become insoluble and form a harmless but unsightly haze or "cloud" when the bottle is chilled or ice is added. To prevent consumers from thinking the whisky is flawed, producers will chill the whisky to near-freezing and run it through a fine filter to strip out those compounds.

However, high alcohol also brings a physical sensation: heat. Ethanol activates the TRPV1 receptors on your tongue, the same receptors that detect heat from chili peppers. A whisky at 60% ABV can be so "hot" that it overwhelms your palate, making it impossible to taste the delicate vanilla, fruit, spice, and oak notes underneath. It can also cause a numbing effect.
