"Lastly, to be called bourbon, the liquid needs to be distilled to no more than 160 proof and entered into the barrel at 125." For other whiskies the liquid must be distilled to no more than 190 proof. David notes that this isn't just common practice — "it's actual bourbon law."


Perhaps it doesn't meet one or more of these standards?
You're probably right. I didn't look up the mash bill on that second one.
