Bigger isn’t always better, but when it comes to whisky, higher proof equals more flavor—literally, as alcohol contains all the flavor molecules found in a dram. (The rest of it is just water.) And cask-strength scotch offers some of the biggest, boldest, richest flavors in the whisky world.
Cask-strength single malts score well with tasters and consistently punch their way to the Whisky Advocate Top 20. Each of these whiskies is cask strength or has minimal adjustment for consistency (typically less than 1% ABV).
