In my parents' and grandparents' houses, whiskey was always, always, served on the rocks. Mid-shelf bourbon or blended scotch. At his age now, my father doesn't drink spirits anymore, he's on a one-wine-or-beer-per-week maximum allocation from his doctor, and likewise all their friends and my older relatives are under those kinds of restrictions.
I remember distinctly when my uncle from Connecticut brought a bottle of single malt scotch over for my grandfather to try, probably around 1976 or 1977. He had to specifically say "try this one without ice", and I believe that it took a few tries before my grandfather got the hang of it (and he still preferred his whiskey on rocks).
For my own part, I like OGD114, EC12, Weller 12 with a couple of ice cubes -- strongly flavored mid-shelfers. My favorite this past summer was the WTRRSB, somehow it just really clicked with the ice.
In this weather the last thing we want is ice inside the house, if anything we want the Bourbon warm.
Great idea Squire. Think I'll a bit of OGDBIB in some hot cider tonight and just look at the ice outside.
