Mortlach – Classic Scottish Distillery Regains Old Glory

History, tastings notes for six Scotches from the “Beast of Dufftown”

Scotland’s Speyside region on the northern tip of the mainland has long been famous for its velvety smooth Single Malt Scotches, which are among the best-known Whiskies in the world—The Macallan, The Glenlivet, and Balvenie.

But there are many other outstanding distilleries near the River Spey that produce legendary Whiskies. And in the small but famous Whisky-making village of Dufftown (home to Balvenie, Glenfiddich, and several other distilleries), you will find a nearly 200-year-old distillery that deserves to be hailed for its understated Single Malt Scotches—Mortlach.

Mortlach is an incredibly special Single Malt Scotch Whisky, known as the Beast of Dufftown

And thankfully, in recent years, more Single Malt Scotches have consistently become available from this distillery nicknamed the “Beast of Dufftown.” Below, you’ll find tasting notes for six different Mortlach Whiskies, including its signature Rare Old, 18 Year Old, 25 Year Old, and three other Single Malt Whiskies aged 23 and 26 years.

Mortlach Tasting Notes

Mortlach’s Rich History

Founded by James Findlater in 1823 (when the Excise Act of 1823 was passed and dramatically reduced the taxes levied on the sale of Whisky), Mortlach was the first legal distillery in Dufftown. (An illegal distillery was previously located at the same site.) The distillery changed hands several times the first few years and was also briefly used as a brewery and a church in the 1840s. Then in 1853, railway surveyor George Cowie took over Mortlach, who brought a precise approach toward making Whisky, according to Donald Colville, Mortlach’s Global Malts Ambassador.

“Mortlach is an incredibly special Single Malt Scotch Whisky, known as the Beast of Dufftown due to its powerful, meaty, vicious character,” Colville said. “This is all down to the fact that it has arguably the most complex Whisky-making process in the world, 2.81 times distilled. This was inspired by the scientific and curious mind of visionary doctor turned distiller, Dr. Alexander Cowie.”

Alexander was George’s son and he began working at Mortlach in 1896 after George died at the age of 80 years old. Dr. Alexander Cowie perfected Mortlach’s distillation process and increased the number of stills from four to six. Mortlach’s scientific approach to making Whiskies famous for their flora and fauna notes explains why Mortlach continues to be so popular around the world more than a century later.

“No other distillery in Scotland or, in fact, around the world has a distillation process which is so complex,” Colville said. “Mortlach, nothing simple about it. Mortlach defies the typical honey, vanilla, and apple notes of Speyside. Its Whisky harkens back to a time when Scotch was bigger, bolder, darker. Now the liquid has been reborn, bringing to life the primal essence of Speyside that once was.”

Worldwide Popularity

While Mortlach has become famous again in recent years for its Single Malt Whiskies, the distillery has also produced Whisky used in several blended Scotches, including serving as the primary Whisky used in many Johnnie Walker blended Whiskies. Mortlach’s connection with Johnnie Walker dates back to 1923 when John Walker & Sons purchased the distillery. John Walker & Sons is one of many companies that eventually became Diageo, the British-based multinational company which launched the Mortlach range in 2014. Along with Mortlach, Diageo owns many other distilleries, including Dalwhinnie, Lagavulin, and Oban.

No other distillery in Scotland or, in fact, around the world has a distillation process which is so complex

“Mortlach is perfect for Whisky blenders as it adds backbone, body, and character to Whiskies, with its muscular flavor that intensifies Whisky blends demonstrating that no other spirit offers the same breadth and depth of flavors as Scotch, and certainly no other liquid is as versatile and has always been a key malt for use in the Johnnie Walker blended Scotches,” Colville said.

And while Mortlach sells well around the world, it’s especially popular in the United States, Europe, and parts of Asia, Colville said. “Due to how well known and loved it is as a Single Malt Scotch Whisky you tend to find the true adorers of Mortlach in the countries where Single Malts are really established such as the U.S., Northern Europe, the UK, and Taiwan and Japan,” Colville said.

Unique Flavors

Colville added that Mortlach pairs well with a wide range of foods, from grilled steaks to many different desserts. “Due to the rich intensity and complex flavors of Mortlach, it pairs beautifully with dark chocolate either in its most basic form or as a dessert like a soufflé,” Colville said. “For a more savory match, red meats such as venison or good-quality beef steaks are also an incredible combination.”

Mortlach for me personifies why Scotch is the world’s favorite Whisky,” Colville said. “The incredible depth of flavor offered by Mortlach makes it an incredibly versatile Scotch, whether it be served neat in its purest form or in a late night Old Fashioned or pre-dinner Rob Roy.”

But even without water, this Single Malt smoothes out quite nicely after a minute or so. With a few drops of water, this Single Malt takes on a tangy, orange-peel-like aftertaste. Definitely a Single Malt for fans of big, bold Whiskies.
