The GlenAllachie Distillery has launched the second edition of its Masters of Wood Series, a 19-year-old single malt Scotch whisky matured in ex-solera sherry casks that held Pedro Ximénez and Oloroso sherry for more than 55 years. The expression is available now with a UK RRP of £224.99 and will roll out globally in the coming weeks.
The Masters of Wood Series spotlights The GlenAllachie’s most unusual and scarce wood stocks. Its debut release, a 17-year-old Mizunara Virgin Oak and Oloroso Sherry Cask Matured expression launched in 2024, was named Best Scotch Speyside Single Malt aged 13 to 20 years at the World Whiskies Awards 2026.

Master Distiller Billy Walker selected a small number of vintage casks that had previously functioned within traditional solera aging systems at Spanish bodegas. The solera method gradually blends younger and older sherries over many years, creating consistency and depth of flavor. Solera casks are seldom removed from the system, making them extremely difficult to acquire.
Walker said: “These are casks that already carried over half a century of sherry history before interacting with our spirit. You are working with time, memory and a structure that has been quietly evolving for decades.”

“Over fifty years of experience in this industry has taught me where to look for casks of real distinction — from partners who, like us, refuse to compromise,” Walker added. “The relationships built on that shared philosophy have given me the opportunity to work with some of the most intriguing and remarkable casks. This Masters of Wood release is one of the very finest examples of cask influence and stands among the most special projects of my career.”
The whisky first matured in American oak ex-bourbon barrels before being transferred into the ex-solera sherry casks for secondary maturation. The Pedro Ximénez casks contribute layers of fig, raisin, and dark molasses sweetness, while the Oloroso casks add drier notes of walnut, dark chocolate, and warming spice.

READ THE STORYBottled at 50% ABV with natural color and no chill filtration, the official tasting notes from the brand describe an intense mahogany color, with brandied plum, intense mocha, and honeycomb on the nose. The palate delivers plum syrup, treacle, warmed heather honey, black cherries, and crystallized cinnamon and ginger.
The packaging features hand-illustrated detailing referencing the solera system, presented in a deep merlot tone intended to reflect the whisky’s natural hue. The expression is available from The GlenAllachie Distillery and through select global retailers.
