Mortlach 20 Year ‘Cowie’s Blue Seal’

Review by: dustbunna


Distillery: Mortlach.

Bottler: Distillery bottling.

Region: Speyside.

ABV: 43.4%.

Age: 20 years. Bottled in 2023.

Cask type: Undisclosed but presumed to be a vatting of bourbon and sherry casks.

Price: Gift, retails around $200 USD locally.

Natural Color. Chill-filtered.

Bottle open across approx. 5 months, notes taken leisurely across that period. Bold notes taken beneath the shoulder, regular-formatted notes taken further into the bottle past the halfway point, no significant change at the heel.


Nose: rich red fruits up front (strawberries and apples), green grass, fresh bread, toffee, caramel, linseed oil, a bit of green melon, blackberry compote, hints of fresh-cut flowers.

Palate: medium body ~ Assam tea, more strawberries and grass, oak spice, red fruit jam, goes way more floral with gardenia, chamomile, honeysuckle, and cut stems poking through.

Finish: medium-short ~ more tea and toffee, more oak tannins on the tail end, black pepper.


Conclusion: This follows a similar profile to Mortlach’s 16yr release but is considerably richer; the additional age contributes a nice bouquet of fruity and floral notes, balanced by black tea-like tannins. The low ABV holds it back a tad (mostly in the less-developed finish), but I notice it less than with younger releases from Mortlach—maybe they don’t have to water their spirit down quite so much to get to 43.4% after two decades of maturation. Folks looking for the distillery’s famed meatiness here might be disappointed: this is firmly in the ‘floral’ Mortlach camp, especially after some air time both in the bottle and sitting in the glass. I was gifted this bottle by some generous friends for a special occasion—admittedly it’s not a whisky I’d go for typically, at the price Diageo is currently asking for it (and twice the price of the 16yr), but it was still really good, and a treat to explore and share. 

Final Score: 84.
