I bought a bottle of Macallan CS NAS lately and I noticed that there are 2 CS expression in Macallan's sherry matured range. The NAS and the 10yo. What is the difference between the two ? The website of Macallan only seems to show the 10yo cask strength. Even where I bought it, they state it as being the 10yo CS in their inventory, which is not.
Is there any difference, or is it just a label change ?
