Why do we drink, even though we know drinking too much isn't good for us? Is it human nature...perhaps in our DNA? Since there are people with a genetic mutation that makes them sick when they drink, why hasn't that mutation spread throughout the world? Is that a sign that perhaps evolution recognizes some benefits from the occasional dram? Those are some of the questions University of British Columbia professor Edward Slingerland looks at in his new book "Drunk: How We Slipped, Danced, and Stumbled Our Way to Civilization." He joins us this week on WhiskyCast In-Depth. We'll expand on the question in Behind the Label with a look at the lack of links so far between whisky and cannabis. In the news, the new Bourbon Alliance is pushing back on Great Britain's American whiskey tariff from both sides of the Atlantic, while whisky is flowing again from one of Scotch Whisky's most historic places.

Is Tennessee Whiskey Bourbon? That argument has divided whisky lovers for years, but Nicole Austin says it is. She's the head distiller and general manager at Diageo's Cascade Hollow Distillery, the home of George Dickel Tennessee Whiskey. To prove her point, she created the new Dickel Bourbon, and she'll make her case on this week's WhiskyCast In-Depth. In the news, Uncle Nearest opens up the latest phase of its new distillery in Tennessee, complete with artifacts from the original distillery Nathan "Nearest" Green and Jack Daniel ran following the Civil War. There's a cease-fire on one front in the trade war between Europe and the United States, and that means the end of U.S. tariffs on single malts from Scotland and Northern Ireland. We'll also have details on an upcoming extra-old whisky from Scotland, and on Behind the Label, we'll look at the difference altitude makes when you're making whiskey.

Earlier this year, Japan's whisky makers agreed on a voluntary definition for "Japanese Whisky" after decades of quietly blending their own whiskies with imported whiskies from Scotland, Canada, and elsewhere. That new definition requires "Japanese Whisky" to actually be fermented, distilled, and matured in Japan, while whiskies blended with imports are now to be labeled as "world blends." The change has put Japan's whiskies under increasing scrutiny and demands for transparency, and one American-based upstart launched its whiskies last October with transparency in mind. While Shibui produces "world blends," it also works with distillers on the island of Okinawa to create single grain Japanese whiskies made from rice. Shibui co-founder Nicholas Pollacchi explains the difference on this week's WhiskyCast In-Depth. We'll also talk about Danish Whisky and a Whisky Danish, too...

Brendan McCarron had a safe, secure job as Dr. Bill Lumsden's hand-picked "heir apparent" on the Glenmorangie and Ardbeg whisky creation team, but he was missing something. Earlier this year, he jumped at the chance to get back to distilling when Distell offered him the chance to become master distiller for its Bunnahabhain, Deanston, and Tobermory distilleries. Brendan did his first public appearances for Distell during Bunnahabhain's virtual Feis Ile events this past week, and we'll hear from him on this week's WhiskyCast In-Depth. In the news, Islay's distilleries have starting to gradually reopen to tourists as pandemic-related health restrictions are easing, while whisky tariffs may be back on the table as the European Union tries to push Great Britain to follow through on key Brexit agreements. We'll also have the details on Uncle Nearest founder Fawn Weaver's mission to help other minorities succeed in the spirits industry and much more!
