The GlenAllachie launches Sinteis Part II.

The GlenAllachie Distillery today, Thursday 21 August, launches the second edition in The Sinteis Series (pronounced sin-teesh), Sinteis Part II - a 2015 Scottish Virgin Oak and Oloroso Sherry Cask Matured single malt.

The Sinteis Series, first introduced in April 2025, focuses on a dual-cask approach, exploring the relationship between virgin oak and traditional sherry casks. Bottled at cask strength, Sinteis Part ll merges 2015 single malt matured in Oloroso Sherry casks with spirit from rare Scottish virgin oak barrels. This combination allows whisky lovers to discover the untapped potential of virgin oak, as it is brought to life through the comforting depth of the sherry influence.

Named after the Scottish Gaelic word for synthesis, and accompanied by the tagline “Two distinct casks. One harmonious synthesis”, the Sinteis Series is the concoction of Master Distiller Billy Walker, whose career spans 53 years in the whisky industry.

A Speyside single malt Scotch whisky that puts the pairing of unusual casks at its heart, Sinteis Part ll (58.2% ABV) leads with notes of mocha, grilled honeycomb and berries on the nose, layered with cinnamon butter and toasted lemon peel. On the palate, heather honey, bright citrus and gently warmed baking spices emerge, followed by gingersnaps and poached orchard fruits, with a lingering finish of mocha and vanilla buttercream.

Sinteis Part ll features eye-catching packaging created by Scottish designer Kayley Barbour, which reflects the fusion of multiple wood types. The exterior carton is textured with a wood grain, while the emblem at the centre of the packaging reflects Scottish oak trees.

Commenting on the new release, Billy Walker said:

“The Sinteis Series is a celebration of creativity at the very heart of whisky making, a chance to explore how different casks, when thoughtfully combined, can create something truly remarkable. With Part II, I was inspired to shine a light on the character of Scottish virgin oak - a rare and distinctive choice in maturation. By pairing its bold personality with the familiar depth of Oloroso Sherry casks, I wanted to craft a whisky that feels both adventurous and reassuringly timeless.
“This second release bursts with layers of indulgent flavour – the vanilla sweetness, honeycomb richness and mocha depth of virgin oak weaving seamlessly with the warm spice and luscious fruit of Oloroso Sherry. It’s a whisky that speaks to both curiosity and comfort.”

Sinteis Part ll, The GlenAllachie 2015 Scottish Virgin Oak & Oloroso Sherry Cask Matured, is available with a UK RRP of £73.99 from The GlenAllachie Distillery and online at www.theglenallachie.com from today. It will become available globally in the coming weeks.

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.
