It's their not-quite-entry-level bottling (and the '13 was quite good). GV ages pretty glacially and that wine is under screwcap, IIRC, which both bode well for it being a really fun wine to drink now. I think Mark is right re: storage, though—I wouldn't be very confident that someone had stored that particular wine well for this long (it's not something a lot of people would intentionally cellar) but if you think that it's not cooked, etc. I'd at least grab one to try.
