This Thursday will be Brian Nation's first St. Patrick's Day outside of Ireland. The veteran distiller joined O'Shaughnessy Distilling in Minneapolis last year after years at Ireland's legendary Midleton Distillery, and as he tells us on this week's WhiskyCast In-Depth, "it was a cold winter."

In the news, Kentucky lawmakers are a step closer to protecting private barrel picks, while Bardstown Bourbon's founders have cashed out in a private equity sale. Diageo will invest millions to build a new carbon-neutral Crown Royal distillery in Ontario, while the spirits giant paid a £1.2 million GBP fine in Scotland for violating environmental laws over a six-year period.
