Crown Royal Bourbon Mash is part of the company’s “The Blenders’ Series” line of whiskeys. The whiskey created controversy due to it being called “Bourbon Mash” as its a blended Canadian whiskey. While it technically utilizes a bourbon mashbill, it is produced in Canada and also utilizes a blend of new oak barrels and used barrels. The TTB initially approved the label (COLA) for this product, only to later revoke this approval after the product had already gone to market. Realizing their error, the TTB granted Diageo a one year time frame to continue using the Bourbon Mash naming convention for this product.
