It is Bushmills Irish Honey and is a blend of Bushmills Original, a "touch" of real Irish honey, and "other natural flavours". And it's a little lighter on the alcohol than straight whiskey, at 35%.
Irish Mist, a honey whiskey liqueur, has been around for many decades. Given where it launched, though, I'm guessing the US market context was more of an inspiration for Bushmills Irish Honey. I was unaware of it until now but there are both Wild Turkey and Jack Daniel's honey whiskey liqueurs, also at about 35% ABV.
I can only speculate how it tastes or what those other natural flavours might be. I don't imagine it's anything like the rather herbal Irish Mist. Wild Turkey's American Honey uses orange and caramel but the official Bushmills tasting notes (provided by Paul Pacult of Spirit Journal) are hinting at apple and pear:
First aromas are of ripe red apple, pears and sweetened breakfast cereal. After allowing aeration the orchard fruit ripeness builds as honey emerges, creating an inviting bouquet.Flavour
Honey ably supports apple, pear, and marshmallow taste notes with ease and aplomb.Finish
Moderately sweet and pleasing because the malt aspect is never in question or lost due to over-flavouring; addition of honey is moderate and subtle.Suggested retail price is $24.99.
