Whisky is usually diluted with water before it’s bottled, following distillation and maturation in casks. Cask strength, scandalously, hits the bottle straight from the barrels.
Cask strength Whisky is also non-chill filtered, a process that usually removes chemical compounds following maturation. That's why cask strength Whisky can go a bit cloudy, which is perfectly natural, and why some people love it – it’s not missing anything.
Cask strength means high alcoholWhisky is typically diluted with water to about 40% ABV. However, cask strength stuff isn’t messed with, so it can remain anywhere between 50-75% ABV. As a rule of thumb, expect a cask strength dram to be around 60-65% ABV.
Barrel strength and overproof are two more expressions tto denote the liquid’s strength. Historically, alcohol was ‘proofed’ by mixing it with gunpowder. If the alcohol content were over 50%, the gunpowder would ignite and seamen would happily accept their overproof Rum. ABV is usually half the overproof figure; thus100 proof is 50% ABV.
In general, Whisky is diluted to cut costs, both for the producer (mostly for tax) and the consumer. Therefore, cask strength Spirits tend to hail from premium ranges, as the producer can fill fewer bottles per cask, and the consumer is purchasing more Whisky, in its purest form, per bottle.
There's more Whisky in the bottle

Cask strength Whisky also allows the drinker an opportunity to playact as the blender. Do with the untouched dram what you will. Some people choose to add their preferred water level, while others take it straight to their tongue.
There are more ways to drink Whisky, but many people argue that adding water is futile and fails to enhance the palate. Other tasters maintain a drop of water can release the Whisky’s expressions and give it an even more distinctive nose.
At the end of the day, it’s a case of personal preference and the most common use of water is to make a strong Spirit more drinkable. However, a good compromise is to drop one small ice cube.
