Here are some information about "Kildalton Style":
"Between 1979 and 1981, Ardbeg produced a very low peaty malt that specialists named "Kildalton Style" after a celtic cross located near the distillery."
Jim Murry's blible(P.29) has two Ardbeg 17yo, in the ealier version, Jim admits he is the creator of Ardbeg 17yo.
And in the present version, Jim thinks it's Macallan without sherry, should be given another name.
OK, no matter ealier version or present version, Ardbeg 17yo uses "Kildalton Style Ardbeg", and if "Kildalton Style Ardbeg" only was produced in 1979-1981, there should be some 20yo above in the present released Ardbeg 17yo, isn't it?
