The GlenAllachie Sinteis Series 2015


25th August 2025
The GlenAllachie distillery announces the release of Sinteis Part ll, The GlenAllachie 2015 Scottish Virgin Oak & Oloroso Sherry Cask.

Sinteis Part ll, The GlenAllachie 2015 Scottish Virgin Oak & Oloroso Sherry CaskThe GlenAllachie Distillery has unveiled the second release in its Sinteis Series (pronounced sin-teesh): Sinteis Part II, a 2015 single malt matured in Scottish Virgin Oak and Oloroso Sherry casks.

Launched in April 2025, the Sinteis Series explores a dual-cask philosophy, marrying the bold character of virgin oak with the timeless influence of sherry wood. Bottled at natural cask strength, Sinteis Part II unites spirit from rare Scottish virgin oak barrels with whisky matured in Oloroso sherry casks, offering a fresh perspective on the untapped potential of virgin oak when balanced by the depth of sherry maturation.

Taking its name from the Scottish Gaelic word for "synthesis," and carrying the tagline "Two distinct casks. One harmonious synthesis", the collection is the vision of Master Distiller Billy Walker, who brings more than five decades of expertise to the project.

This Speyside single malt which has been bottled at a cask strength of 58.2% ABV and it is said to open with aromas of mocha, honeycomb and ripe berries, layered with cinnamon butter and toasted lemon peel. The palate delivers heather honey, bright citrus and gentle baking spices, followed by gingersnaps and poached orchard fruits, leading to a long finish of mocha and vanilla buttercream.

Presented in striking packaging by Scottish designer Kayley Barbour, Sinteis Part II reflects its wood-forward character. The textured carton mimics natural grain, while the central emblem draws inspiration from Scotland's native 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."
