Me neiher, but consider this;
The distilery knows more about their whisky than most of he rest if us. They spend a lot of time trying to get the flavour profile right and getting he strength right to make he whisky sing.
Why on earth would i want to add water to a £175 bottle of balvenie tun 1401 when one of he best whisky blenders in he world has chosen certain casks for that bottling to taste a certain way. And water from a tap why is nothing like he original water....just mindless.
No probs if you want to stick it in a bottle of 12yr fiddich, i just dont own any :-D
and the stuff i do own i aint messing with.
