UK. Bushmills Irish Whiskey has unveiled the tenth and final release from its Causeway Collection. The rare 33 Year Old Port Cask will be sold exclusively in World Duty Free stores across all Heathrow Airport terminals, including its World of Whiskies shops, from 1 March.
The product (RSP £1,245) – created by Bushmills Master Blender Alex Thomas and distributed by Proximo Spirits – is the oldest expression ever released from The Old Bushmills Distillery, which is reputed to be the world’s oldest licensed whiskey distillery. Just 690 bottles of the cask finished, cask strength (53.3% ABV), non chill-filtered Irish single malt will be available.

Dufry UK Category Manager for Liquor Paul Martin said: “We are really excited to be able to offer to our customers at Heathrow Airport such a rare and highly sought after product. We know that in travel retail customers are always looking for something a bit different or unique and this most definitely ticks that box. We expect it to be a great success.”
Filled on 19 April 1989, the rare bottling has spent 33 years being matured in fortified wine casks from northern Portugal. Thomas has imbued with the product with dark fruit flavours, including blackcurrants and blackberries.
“We are proud to build on the growing legacy of The Causeway Collection and excited to share our 33 Year Old Port Cask with whiskey fans travelling through Heathrow from all corners of the globe” – Bushmills Master Blender Alex Thomas
The Causeway Collection is a unique selection of cask-finished and fully matured Irish single malt whiskeys. The current collection features ten expressions which have been made available across seven global markets, including Travel Retail, Ireland, the UK, France, Germany, Australia and Poland.
With its close proximity to The Old Bushmills Distillery, the distiller noted that the famous Giant’s Causeway landmark on the coast of Northern Ireland’s County Antrim has been a source of inspiration for generations of Bushmills’ Master Blenders. Like the columns of basalt rock, The Causeway Collection is forged in sea air and mineral-rich water.
Thomas said: “It is truly a privilege to work with such rare whiskeys in The Causeway Collection. They are the fruits of over 400 years of Bushmills whiskey-making tradition, each expertly created and nurtured over decades.
“The Causeway Collection is a celebration of our passion for single malts, and these special whiskeys are our greatest treasures. At Bushmills, we continue to innovate and create new expressions to excite the whiskey community. We are proud to build on the growing legacy of The Causeway Collection and excited to share our 33 Year Old Port Cask with whiskey fans travelling through Heathrow from all corners of the globe.”
