Labels submitted to the TTB have revealed Siren’s Song, the ninth edition in WhistlePig’s The Boss Hog series. Siren’s Song will be an American straight rye whiskey finished in Greek Fig Nectar and Scratch Tentura (Greek liqueur) barrels.
It will have no age statement; its alcohol content will vary from bottle to bottle since it is a single-barrel release. If past releases of The Boss Hog are any indication, other barrels should fall within a similar ABV range.
