Awarded AOC in 2003 say Wiki.
It's been around since the 70's, I remember in the mid / late 70's, early days for them, when Majestc first started stocking it from a producer (whose name escapes me just now) that they no longer use.
Goose will tell you if it's any good though. I've bought in the past for novelty reasons and to try. But now, the vineyards re-planted with SB and S.Gris, some 40 years ago should be maturing, so there is every reason to consider it.
A map showing the area south west of Chablis and north east of Sancerre should indicate some other odd balls
