Bushmills Unleashes the Oldest Irish Single Malt Ever – A 46-Year-Old Whiskey That Made History
Bushmills, the world’s oldest licensed whiskey distillery, has shattered records with its latest release—Secrets of the River Bush, a 46-year-old single malt that stands as the longest-aged Irish whiskey ever bottled. This ultra-rare expression, distilled in 1978, was matured exclusively in oloroso sherry casks, offering an unparalleled depth of flavor and history.
A Whiskey Born in the Darkest Times
At the time of its distillation, Irish whiskey was at a crossroads. Only two distilleries remained in operation across Ireland, and Bushmills had yet to introduce its first single malt. Yet, against all odds, this whiskey endured. Today, it represents not just a record-breaking achievement but the extraordinary revival of Irish whiskey, which now boasts over 50 active distilleries.
Masterful Maturation – The Secret Behind Its Legacy
What makes Secrets of the River Bush truly exceptional is its rare aging process. Unlike most whiskeys that begin in ex-bourbon barrels before a secondary finish in sherry casks, this whiskey spent its entire 46 years in 500-liter oloroso sherry European oak butts. The result? A dark, cola-like hue and a flavor profile enriched with deep dried fruit notes, yet still retaining Bushmills’ signature smooth, fruity essence.

Inside the Vault: How Nature Shaped Perfection
The casks were stored in the legendary Warehouse 8, the oldest maturation house at Bushmills, where minimal temperature fluctuations allowed for slow, steady aging. European oak, with its tighter grain, further controlled the interaction between wood and whiskey, preventing it from becoming overly oaked despite nearly five decades of aging.
The Art of Precision: A Cask-Strength Wonder
Bottled at a cask strength of 46.3% ABV, this whiskey defies the norm of older releases, which often lose proof due to evaporation. The reason? Exceptional wood management and the steady climate of Northern Ireland’s north coast. Master Blender Alex Thomas, who has overseen its development since 2004, carefully monitored the cask every three months—and in the final stages, every week—to ensure perfection at the moment of bottling.

With over half a million barrels aging at Bushmills, could an even older release be in the works? When asked, Thomas remained tight-lipped: “Like the River Bush keeps its secrets, that’s mine.”
For whiskey collectors and connoisseurs, Secrets of the River Bush is more than just a bottle—it’s a piece of Irish whiskey history, a testament to resilience, and a celebration of masterful craftsmanship. This release cements Bushmills’ legacy, proving once again why it remains a true icon in the world of whiskey.
