In hotter climates like Kentucky (Bourbon) or India, water often evaporates faster than alcohol, which can actually cause the ABV to increase during aging. How Alcohol Percentage Affects Flavor

Some examples of popular whiskies and their ABV:

Many enthusiasts look for a minimum of 46%. At this strength, the whisky typically does not require "chill-filtration" (a process that prevents the liquid from becoming cloudy when cold but can strip away flavorful oils). 3. Cask Strength (52% – 65%+ ABV)

When a label says “40% ABV,” it means that 40% of the liquid inside the bottle is pure ethyl alcohol, and the remaining 60% is water (along with trace amounts of congeners, esters, and other flavor compounds). For example, a standard 750ml bottle of 40% ABV whisky contains exactly 300ml of pure alcohol.
