I've never had Scotch anything but neat but I tried a a couple teaspoons of good water and it really did bring out some other notes. Hmm, might be a way to stretch it a bit too!
I add some water to cask-strength liquors. But I've noticed that the best way to bring out a good scotch, bourbon, or other liquor is to pour it into a glass (I usually use one of the Glencairn glasses.) and let it sit and open up for a good 30 minutes or more. It really smooths out and the flavors open up very nicely. It works very well with a nice dark rum, too. Just gotta have patience.
1 ice cube loses nothing
I find this does not work at all for blends
Except for half the nose.... Never chill a malt
I beg to differ. One ice cube changes little, except the heat. However, I am trying my Caol Ila with just a few drops of water. Not much difference than neat, frankly.
In case anyone is wondering, a bit of water in a dram of scotch is how it is traditionally enjoyed. Without the water, you really are missing out on all that is in your scotch. I extend this practice to all whiskey. Just few drops or more depending on strength. You really want to cut the alcohol a bit so it doesn't get in the way. With that said, and more importantly, enjoy your whiskey whichever way you like!
