The Causeway Collection is Bushmills' rare-cask series, released in limited numbers and named for the UNESCO-listed Giant's Causeway that sits just beyond the distillery walls. This 14 Year Old expression is finished in casks that once held Pomerol — the Merlot-dominant wines of Bordeaux's Right Bank — and bottled at a muscular 54.1% cask strength.
The nose opens on crushed blackberry and violet, with dark plum skin and a ribbon of cocoa weaving through. Beneath the wine influence, the classic Bushmills signature is still audible — green apple, pear, triple-distilled softness — but the Pomerol has draped it in something darker and more brooding. A drop of water releases dried rose and bitter chocolate.
On the palate the whiskey is rich and, unusually for Bushmills, grippy. Black cherry and ripe plum arrive first, chased by cocoa nib, mocha and a tannic edge borrowed directly from the Merlot wood. The cask strength delivery gives everything weight without heat — this is a whiskey that fills the mouth rather than burns it.
The finish is long and drying, faintly peppery, with dark berry compote lingering alongside espresso grounds and sweet oak. It's a striking departure from the standard Bushmills house style: where the core range whispers orchard and honey, the Pomerol Cask speaks in the lower register of red wine, dark fruit and structured tannin. A collector's bottle, but also a drinker's — worth finding for anyone who wants to see what triple distillation can do when dressed in serious Bordeaux wood.
