That's the thing...I don't think this is new. My assumption is that this was the PROTOTYPE for what we now know as Saz18. I think JH just dipped into his library of OLD samples and found it, and decided to share/brag.
Right, this was my assumption.
I just found John Hansell's tweet from 12/30/12 and this is the original text:
"What I'm drinking tonight: the prototype to what is now the legendary Sazerac 18 yr. rye whiskey. But 110.2 proof!"
