Smooth Ambler Old Scout ‘Whiskey Revolution” 6 Year Old Single Barrel Bourbon Whiskey 750ML

Old Scout is the family of sourced whiskeys. Old Scout Bourbon Single Barrel is the way of turning over the selection of casks for you to choose from. What is the selection of a selection even called?

Is there a phrase for creme de la creme de la creme?
Single cask of this rich, high-rye Bourbon from Indiana.

Same mashbill as the Old Scout Bourbon, but with more proof.
