The GlenAllachie adds to Sherry Series with rare Palo Cortado matured single malt

Building on the success of a trio of initial releases, The GlenAllachie has today, April 21, unveiled the fourth chapter in its celebrated Sherry Series: the new 11-year-old Palo Cortado Sherry Cask Matured Single Malt Scotch Whisky.

First launched in April 2024, the Sherry Series explores the influence different secondary Sherry cask maturations can have on whisky of the same cask history, with this latest expression finished in one of rarest and most intriguing styles of sherry – Palo Cortado – showcasing the distillery’s commitment to exceptional wood management.

This new 11-year-old expression enjoyed a period of secondary maturation in Palo Cortado sherry casks and delivers a beautifully layered flavour experience with notes of ripe plums, dark mocha and warming cinnamon spice, balanced with refined dryness and depth.

Originally born of a happy accident in the mid 19th Century and now revered by connoisseurs, Palo Cortado is the rarest and most enigmatic sherry style. It begins as a young Fino (the driest and palest sherry style) before being refortified to 17.5-18% ABV, which causes the protective flor yeast to dissipate and triggers oxidative aging.

This unique process gives it a signature balance – the flavour profile sits between Amontillado and  Oloroso, combining the aromatic finesse of the former with the structure, body and richness of the latter.

Master Distiller at The GlenAllachie, Billy Walker, commented:

“With the Sherry Series, we set out to create expressions that spark curiosity and invite deeper conversation. The extended secondary maturation allows the spectacular nuances and variations of each sherry style to reveal themselves completely, taking centre stage in a way that’s both bold and refined.

In this bottling, we have combined The GlenAllachie’s signature heather honey character with Palo Cortado’s deeply complex, sweet and nutty aromas – creating a whisky with a remarkable spectrum of flavour that has surpassed our expectations.”

Each cask in The Sherry Series begins its journey in the renowned sherry-producing region of Cádiz, where premium casks are sourced from the distillery’s trusted bodega partners before being transported to Speyside. Each expression is initially matured in American oak ex-Bourbon barrels before undergoing secondary maturation in a single, expertly selected sherry cask type, allowing the distinct characteristics of the wood to shine through.

Bottled at a robust 48% ABV, this latest expression is presented at natural colour and without chill filtration, ensuring the whisky retains its full character and complexity.

With this latest release, The GlenAllachie continues to push the boundaries of cask maturation, offering whisky enthusiasts a rare opportunity to experience the nuanced influence of Palo Cortado sherry on Speyside single malt.

About The GlenAllachie Distillery

One of Scotland’s few independently owned and managed distilleries, The GlenAllachie is led by industry veteran, Billy Walker, who boasts over a half-century’s tenure in whisky. With 16 on-site warehouses holding over 50,000 casks, The GlenAllachie Distillery have complete control of the end-to-end maturation process.

Since re-emerging under independent ownership in 2017, The GlenAllachie has made bold, strategic choices rooted in flavour integrity over volume. By fine-tuning fermentation practices, streamlining production, and investing heavily in cask management, the distillery has cultivated a house style renowned for depth, complexity, and individuality.

Beyond the stillhouse, The GlenAllachie’s influence continues to grow, with high-profile and innovative releases such as The Sinteis Series, and age-stated limited editions earning global acclaim. The distillery’s commitment to transparency – bottling at natural colour, non-chill filtered, and often at cask strength – underscores its dedication to the discerning whisky drinker.

Prioritising the production of quality spirit, the GlenAllachie Distillery chose to reduce its production capacity from four million to around one million litres of alcohol and increase its fermentation period to 160 hours – almost three times the industry standard – for an ester-rich, fruity spirit.

The GlenAllachie also maintains a strong focus on sustainability and provenance, with local sourcing and traditional methods guiding much of its ethos. Supported by the Scottish Industrial Energy Transformation Fund (SIETF), a state-of-the-art Mechanical Vapour Recompression (MVR) system was installed at the distillery to capture and recycle waste heat from distillation, using it to reheat the stills. The result is a distillery that not only honours Scotch whisky heritage but actively shapes its future.
