Paper Trail
First Public Peek: Castle & Key Experimental Whiskey Label Approved
A new straight rye whiskey COLA for Castle & Key Experimental Whiskey just showed up in the TTB Public COLA Registry (Kentucky).
Castle & Key Experimental Whiskey has a fresh Certificate of Label Approval on file with the Alcohol and Tobacco Tax and Trade Bureau — logged as a straight rye whiskey COLA completed 09/23/2026 out of Kentucky.
Street dates come later. For now, this COLA is the public paperwork flare that an expression, finish, or packaging run may be moving. We’ll call it an early look — and Labels stays stocked as new approvals show up.
