I had heard the single malt line too but seems to be just a plain simple blend in the end. Pretty boring
I suppose that this was the hook up with Cooley but when that fell through so they probably reverted to a 10yo blend.

The one good thing that came out of all this is that the constituents of what would be the Tullamore 10yo Malt are now being successfully marketed as the Tyrconnell finishes.
Madeira, Port & Sherry.

With every cloud as they say ...
