Thanks for the info!

I apparently had "grain whisky" and "grain neutral spirits" confused. I am still a little cloudy on how grain whisky can be included in a product calling itself "100% scotch whiskies" but I guess as long as I know the makeup of my bottle, the terminoligy isn't critical.

What I meant by older bottlings being better, at least in the bourbon world, was that back in the 50s, 60s, 70s, etc, producers did some things that resulted in a better end product vs what's being put out today. Not that just time in a bottle on a shelf would improve the contents.

Lower distillation proof, higher bottling proof, more aging before bottling, older wood used in barrels, etc were all things that helped to make those vintage bottles better than the current offerings. I know things like Wild Turkey and Old Grand-Dad were way better in the past. Not sure if anything like this was going on in the scotch world.
