As far as I know there is no distinguishing between bourbons if they are from a one distillery or blends. Often we as drinkers dont know

High West has a bourbon out I see and I see its a blend

Whiskey#1: 6 year old Bourbon distilled and aged at the old Seagrams plant in Lawrenceburg Indiana. Mashbill from 75% Corn, 20% rye, 5% barley malt.

Whiskey#2: 10 year old Bourbon distilled by Four Roses. Mashbill from 60% Corn, 35% rye, 5% barley malt.

The name will be American Prairie Reserve and I have read that 10% of the proceeds will go to http://www.americanprairie.org/
