Yes, Jim Murray assisted with the concoction of the first release of 17yo, something that he's very quick to remind people of!
According to "legend", a bit of the so-called Kildalton stock (unpeated Ardbeg from 1981) went into the vatting, so the first release was certainly not as smoky/peaty as the usual Ardbeg style.
Owing to the long closures and periods of non-production, the holes in the stock range meant that the 17yo was always going to be a limited product.
I understand the Nam Beist bottling is intended as a replacement for the 17yo.
