This is the first Boss Hog release since Pickerell’s passing in 2018. The series is one of experimentation and showcasing the different possible expressions of rye whiskey. Previous versions include The Spirit of Mauve, finished in apple brandy barrels and the Black Prince in Armagnac barrels.
Next up, the umeshu. It is a Japanese liqueur made by steeping fresh Japanese plums (ume) in shochu/white liquor and sugar. The result being a liqueur with a blend of flavor notes, both sweet and sour. WhistlePig is one of the first American distilleries to use umeshu barrels and this release is a collaboration with the Kitaya brewery on Japan’s Kyushu island.
“It was an honor to work alongside the team at Kitaya to bring this collaboration to life in the form of the first American whiskey finished in Japanese umeshu barrels,” said WhistlePig CEO Jeff Kozak at the time this whiskey was released. “With the introduction of The Samurai Scientist, WhistlePig continues to pave the way for innovation across the rye category. Dave Pickerell committed to five promises for The Boss Hog, including being distinctly unique from anything we’ve done before. He had a thirst for exploring and trialing techniques from around the world, and Takamine was likeminded in propelling whiskey innovation across continents. This vision continues to drive us to explore beyond the limits of American Whiskey.”
“We finished one of our oldest whiskeys in barrels that held Kitaya’s eleven-year-old umeshu,” addedWhistlePig master blender Pete Lynch. “With umeshu being an intensely aromatic spirit, it does not take long to impart deeply complex flavors. Each barrel of The Samurai Scientist is bottled at proof. Only 90 barrels exist and each bottle notes the barrel number and proof, ranging between 120 – 122.”

Tasting Notes: WhistlePig The Boss Hog: The Samurai Scientist
Vital Stats: 120-122 proof, 60-61% ABV. Aged 16 years. ~ $499 per 750ml bottle.
Appearance: Burnt orange, topaz, a reddish rust. Note about the bottle, Whistle Pig crafted a samurai-dressed pewter topper in memory of Jokichi Takamine, the “samurai chemist” who taught koji fermentation to American whiskey makers in the 19th century.
Nose: Barrel strength, so a lot of alcohol up front. Beyond the initial hit, could pick up a hint of citrus, as well as toffee and clove.
Palate: A heck of a lot of citrus and rye spice. In the middle found notes of tobacco and baking spices, with a long finish of caramelized sugar and oak. This one was really complex, offering a bouquet of flavors throughout.
