Insider knowledge: Glenrothes 23 Year Old 1990 - Old and Rare (Hunter Laing) whisky is named whisky by virtue of the fact it's from Scotland. If distilled in America the spelling would be Glenrothes 23 Year Old 1990 - Old and Rare (Hunter Laing) whiskey, as opposed to whisky.
Yes, this came from a sherry hogshead indeed. We forgot to add that in our bottling note, but have now corrected it, thank you very much! --The Chaps at Master of Malt
