The problem with Inis & Gunn is there is no consistency. I had one last year that was mellow and slightly sweet with a distinct aftertaste of whiskey. Not too bad but one would be enough.
On the strength of this I bought a 750 ml bottle at Christmas thinking it might go well with a mince pie and whiskey cream. It was awful, it tasted like someone had stirred sugar into a weak solution of vanilla and vinegar. I cleaned the drains with it!
