Croithlí Distillery: A Donegal Whiskey Tradition Reborn

Producer Story | Distillery | Irish Whiskey

Tucked into the wild, remote landscape of County Donegal in Ireland's northwest, a whiskey tradition once thought lost is being brought back to life.

Croithlí Distillery is reviving centuries of spirit-making history, drawing on the heritage of the Donegal Gaeltacht and pairing it with traditional craft and a modern eye for quality.

This is more than a distillery story. It's about reconnecting a place, its people, and a tradition that shaped the region for generations before falling silent.

Roots in Donegal's Distilling Past

Donegal's link to Irish spirits stretches back a long way. Early monastic communities in the region are believed to have developed distillation techniques for herbal remedies and spirits centuries ago — practices that would go on to influence whiskey-making itself.

That knowledge passed down through generations of local distillers and poitín makers, who kept the craft of working grain, water, and copper alive long after formal whiskey production had disappeared from the area.

Croithlí Distillery picks up that thread today, producing Irish whiskey shaped by Donegal's own history and identity.

A Commitment to Traditional Method

Traditional technique sits at the centre of everything Croithlí makes.

Where most distilleries have moved on from it, Croithlí still uses direct-fired distillation — heating its copper stills with open flame rather than steam. It's a slower, more demanding method, but one that builds greater depth and complexity into the finished spirit.

The distillery draws its water from the River Crolly, which flows down from the Derryveagh Mountains, and sources Irish-grown grain — premium malted barley alongside specialty malts chosen for the flavour they bring.

Double distillation and hands-on craftsmanship round out the process, producing a whiskey with genuine character while staying true to the refinement Irish whiskey is known for.

A Building That Has Seen Several Lives

The distillery's home has its own story, long before whiskey entered the picture.

Built in 1901 to support local communities in the Donegal Gaeltacht, the building spent decades as a centre of regional craft and industry. It once housed Donegal Carpets, a business whose work was placed in locations as significant as Áras an Uachtaráin, Buckingham Palace, and the White House — and later became known for producing the much-loved Crolly Dolls.

Now restored, the building has entered a new chapter, no longer weaving carpets or crafting toys, but distilling premium Irish whiskey while carrying its long craft history forward.

Where Time and Wood Do the Work

Croithlí sees maturation as central to what makes a whiskey great.

The spirit rests in a range of carefully chosen oak casks, including:

• First-fill bourbon barrels

• Oloroso sherry casks

• Virgin oak

• Pedro Ximénez-finished casks

Each cask type leaves its own mark, giving the final expressions a character shaped as much by the wood as by the distillers themselves. Nothing is chill filtered or artificially coloured — the whiskey is left to show its true character from cask to bottle.

Nearly 180 Years in the Making

Croithlí Distillery set out with a single mission: bring whiskey production back to Donegal after an absence of almost 180 years.

The founders researched the region's distilling history closely, restored traditional copper stills, and converted a historic building into a working distillery built for the present day.

After securing Donegal's first whiskey licence in nearly two centuries, Croithlí began producing small-batch whiskey rooted firmly in the region it comes from.

Production is led by Master Distiller Julio Diana and his team, who continue developing expressions that reflect Donegal's distinct character.

What Comes Next

Croithlí Distillery is more than a producer of whiskey — it's the revival of a community's story, a historic site, and a tradition that had all but disappeared.

By combining old technique, local resources, and modern craft thinking, Croithlí is introducing a new generation of drinkers to the spirit of Donegal.

Every bottle carries that origin with it — shaped by fire, copper, water, wood, and time.
