Not in the Irish Whiskey industry but it has become very prevelent in the Scotch whisky industry especially from the younger distilleries.
I actually tasted Kilbeggan New Spirit fresh and warm directly from the still and it seem like a very nice spirit. Well worth a taste but I'm not sure what % the samples are. But it was about 73% the day I tasted it.
Really looking forward to tasting this as whiskey
