Gordon & MacPhail has released thousands of single cask bottlings over the years, including the two oldest whiskies ever bottled: 70-year-old casks of Mortlach and Glenlivet single malts. Now, the family-owned company is reviving its "Rare Old" series of single malts with a series of new releases. Many of those new releases are from distilleries that closed 30 years ago this year during one of the industry's biggest cutbacks in distilling capacity. We'll discuss those distilleries and whether a new "whisky loch" is filling up with Gordon & MacPhail's Michael Urquhart in this week's WhiskyCast In-Depth. In the news, another Indian distillery expands its single malt lineup, Miltonduff Distillery gets a turn in the spotlight, and more new distilleries are coming to Northern Ireland. This week's tasting notes include Ardbeg's new Ardbog, The Glenlivet's new Alpha single malt, and Forty Creek's upcoming Heart of Gold Canadian whisky.
