Re: RE: Tyrconnell Finishes Port/Sherry/Madeira/Single Cask
No, they are not chill-filtered (according to Noel Sweeney, Cooley's Master Blender at a tasting I attended).
As I understand it, chill-filtering is unnecessary at 46% and above. I presume they do not go to the expense of it if they don't need to. All it would achieve is the removal of some flavour elements, which would not be desirable.
