Purchased a few while visiting the winery in November 2012.

From the winery's website:

Black Prince Cabernet Franc Terroir Elite 2010

Made from County grapes provided by two longtime local growers and our own Estate. Prince Edward County is one of the few places on Earth where both oak and grapes grow side by side and Black Prince Winery is most proud to release the first Cabernet Franc aged for 18 months in Prince Edward County white oak barrels.
