Who isn’t excited when they realize it’s Boss Hog o’clock? WhistlePig, known for their way with rye, were recently up to their old tricks again (or, one could argue, a new trick – I’ll let you decide) with what some are calling “wild,” and “labyrinthine:” Siren’s Song. I don’t think it’s far outside their normal metier, but what is wild is that there’s no age statement, though WhistlePig claim it’s “some of the oldest rye on the farm.” 

In keeping with the international inspirations of prior Boss Hog editions, Siren’s Song is an homage to ancient Greece. Liz Rhoades and Meghan Ireland of WhistlePig crafted their own barrel finish for the first time. This whiskey is rested first in a Greek fig nectar cask, and then in one that contained Tentura, a spicy, honeyed liqueur. The Tentura was made in-house with cinnamon, clove, nutmeg and orange peel.

Tentura often has a base of brandy, but sometimes rum, and its color ranges from amber to dark orange-red. Typically served neat or over ice as a digestif, it can also be used in cooking and cocktails. Another name for this liqueur is transliterated as moschovolithra, which means “she who throws scent.” It’s been made in the Greek wine-producing region of Patras from the 15th century, by some estimates. 

Patras is best known for the fortified red wine Mavrodaphne. This technique was developed after a local producer traveled to Douro in Portugal and learned how port was made there sometime in the mid 19th century. Patras also produces dry white wines from the Roditis grape and sweet white wines from Muscat.

But I digress. Expanding the tradition of bespoke pewter stoppers, The Boss Hog IX comes with adorned with one of nine (!) different muses (deep breath): Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, or Urania (in sow form, of course). This reviewer’s sample was guarded by Thalia. As in years past, these were crafted by Danforth Pewter of Vermont.

Nose: Officially, it smells awesome. Sweet cinnamon buns with vanilla glaze and the warm rich scent of fig.
