I have found that a complex blended scotch whisky goes great with ice and soda. Of course, I make my own (scotch). Here's how I did it tonight.
I took some Famous Grouse 18 year old vatted malt. I added some Ardbeg (the vatted version with the Celtic name that starts with "U").
Then I added some miscellaneous mixed scotch I keep (mostly malt with some grain from the blended whisky component).
Still wasn't right, so I added some 20 year old CC. Remember, CC or any Canadian whisky is essentially like a Scotch grain, so this provided a "display" function (Scots blending term).
Like the focus feature on a camera, this brought the drink into perfect focus. It is fine for neat sipping, but I want to go "whisky-soda" tonight.
Add as much again of plain Perrier, and then lots of rocks. Now it's rockin', a Scotch Mist on steroids.
