I came across a website that has a "Cache" of Hannisville Rye
(and whiskey & gin) believed to be distilled in 1863:
Finest & Rarest
with "Tasting notes on the rye, from Dave Hughes, acclaimed author
and internationally respected wine and spirits judge for over 30 years"
Since they're going to offer 200 ml bottles for sale, I wasn't sure
whether to post in the Rye, History, or Good Deals sections.
