Actually no and I didn't know much about the region either until I really started to research the region as I prepared for my interview with Duncan Ross, founder of and winemaker for Arrowhead Spring Vineyard.
It turns out that the Escarpment itself--the geological feature, not the region--is the very reason why they can ripen grapes fully so close to the Canadian border. In fact, it's the second warmest region in New York state. Long Island is the warmest.
Arrowhead Spring is scheduled to open their tasting room and release their first wines next spring. But, you can learn all about Duncan, the unique terroir of the region and his new vineyard over at Appellation America.
