Review: Diageo Scotch Whisky Rare Series 2026

There’s no whisky company that loves special releases more than Diageo, and for summer 2026, it’s bringing us a brand new series of ultra-rare offerings to salivate over. The new Diageo Rare & Exceptional Series is awfully precious: It’s only going to be sold through Diageo’s Private Client network, not standard retail channels.

The inaugural lineup of the Diageo Rare Series spans five single malts, the youngest of which is 33 years old and the oldest of which is 55 years old — the oldest single malt Diageo has ever released. All five releases yielded stock to the tune of just a few hundred bottles each. (Details on each release follow.)

Diageo Rare Series Blair Athol 34 Years Old 1991 Review

Highland malt, aged in a refill European oak sherry cask (the first time Blair Athol has ever been aged in sherry) and finished in Pedro Ximenez-seasoned new American oak hogsheads. Wild on the nose, this whisky is almost overwhelming with the unmistakable aroma of PX sherry, intense with notes of raisins and incense, developing to feature dark chocolate layered over cinnamon-spiced caramel.

The palate is instantly rich and spicy but quite weighted down by so much sherry influence. An intense shade of burnt umber, the warming malt leans into its nutty elements, hazelnuts giving way in time to earthy graphite and slate, then anise crumbled atop forest floor notes. Raisins cling hard on the finish, almost pruny thanks to a thick, undulating body that never wants to release its grip. 101.6 proof. 347 bottles produced. A little goes a long way. B+ / $900

Diageo Rare Series Talisker 33 Years Old 1992 Review

Aged in refill bourbon and sherry casks — and finished for over 20 long years in Amoroso-seasoned American oak hogsheads. (Amoroso is made by blending PX or moscatel wine with oloroso sherry.) The nose is extremely effusive with PX sherry aromas — far more than the Blair Athol — with an intense aroma of raisin and baking spice, leaning into cardamom and clove as it develops in the glass. To call this atypical of normally smoky-briny Talisker would be the understatement of the year. I think it’s safe to say this is unlike any Talisker ever produced.

The fruity palate immediately approximates fruitcake wrapped in licorice twists — very sweet with notes of candied fruit and finally finishing with mild hints of classic maritime notes, gently salty and windswept with wisps of bonfire smoke. Tasted from a very small sample, sadly. 120.2 proof. 331 bottles produced. A- / $1300

Diageo Rare Series Caol Ila 42 Years Old 1983 Review

Aged in bourbon barrels, married in sherry puncheons for an unstated length of time. Timeless notes of ultra-smoky Caol Ila permeate the nose, a classic seaside aroma of beach bonfire and salty seaweed pulled wet from the ocean. The palate reveals something far sweeter than you’d expect from the nose alone, a mix of preserved citrus, baking spice, and flambeed banana, all laced with honey and smoldering with notes of gritty creosote and bonfire ash. Not too far off your Caol Ila expectations, despite the extremely advanced age. 112.8 proof. 318 bottles produced. B+ / $3000

Diageo Rare Series Clynelish 42 Years Old 1983 Review

Highland malt aged in American oak hogsheads, no finish. A classic, well-aged Scotch that, while straightforward, is full of charm. Almonds and nougat inform a nose that otherwise sees effusive brown sugar, toasted cereal, and a lively floral character featuring lilac and honeysuckle. That impossible freshness follows through on the palate, sweet with toasted marshmallow, honey, and a floral quality that somehow gets bolder and bolder as the finish approaches. Quite racy at 49.5% abv, the spiced/salted caramel notes on the finish come out of nowhere considering this whisky’s advanced age. 99 proof. 160 bottles produced. A / $4000

Diageo Rare Series Glenury Royal 55 Years Old 1970 Review

So here it is: The oldest single malt in Diageo’s history, from a distillery that was shuttered in 1983. Aged in American oak hogsheads and married in European oak puncheons. Somehow still clinging to 62.4% abv, unheard-of for Scotch whisky of this age. I’ll be frank that this isn’t my favorite whisky in the lineup. The nose is sharp and biting, hard-edged with black pepper and a solvent note that does it few favors. That said, the aroma is completely unique, a mix of spice box, cedar planks, potpourri, and wood varnish all in a swirl. The palate makes a sweeter diversion but remains complex and scattered, with burnt almond evoking a light smokiness, finishing with menthol and more of that industrial edge. Water — the only time I added it to anything in this lineup — helps quite a bit, coaxing out a waxy honey character and aromatic pear notes. Should you pony up for a glass of this, you’ll want water at the ready from the start. 114.8 proof. 232 bottles produced. B / $6350
