The O’Mahony Craft Cooperage in the shadow of the Knockmealdown Mountains represents the first white cooperage established in Ireland in nearly a century, according to founder Killian O’Mahony. The workshop features retired barrels used for storing, transporting, and aging foods, including an old tumble churn and a herring barrel equipped with a low tap to siphon off fish oil once used for lamp fuel, alongside newly hewn tankards, miniature barrels, and plunge butter churns.
The Revival of White Coopering in Ireland
According to Killian O’Mahony, white coopering focuses on creating vessels for household use—such as tankards, churns, pails, and tubs—differing from wet coopering, which keeps liquids inside barrels for brewing and distilling, and dry coopering, which keeps moisture out for transporting apples, grain, and flour. Historically, these household items were tied to an Irish tradition known as the “newlywed ticket,” where family members contributed funds to a local cooperage to purchase a complete kit of domestic vessels for a new household.
The last widely known white cooper in Ireland was Ned Gavin, who worked until the 1980s. Killian O’Mahony entered the trade after becoming the first apprentice at the Midleton Distillery cooperage in 2013 in 40 years, qualifying as a cooper by 2017 and spending a decade repairing whiskey barrels before launching his own white cooperage.
Pro Tip: According to Killian O’Mahony, maple is the preferred wood for butter churns because its natural antimicrobial properties make it food-safe, whereas oak is utilized for tankards and barrels designed to impart flavors.
Family History and Craftsmanship Roots
Researching his family background revealed deep historical ties to the trade, according to Killian O’Mahony. His great-great-grandfather, Bartholomew (Batt) Ahern, served as the chief blacksmith at Midleton Distillery until 1932. Additionally, family history gathered by Mary O’Mahony Lupton in Texas documented his great-great-grand-uncle Henry O’Mahony, an apprentice cooper in Skibbereen who fled to New York due to his association with the Land League and worked hooping apple barrels.
Killian O’Mahony’s interest in household coopering was further inspired by Scottish cooper Ian Andrews, whom he first met in 2013 at age 72. Today, the modern workshop produces custom casks and churns using retired distillery and winery barrels made from American and European oak, chestnut, and maple.
Did You Know? At its peak before the end of the 19th century, Ireland supported 11,000 coopers before demand declined due to modern food storage and transport methods, according to historical accounts cited by Killian O’Mahony.
Custom Casks and Modern Culinary Trends
The O’Mahony Craft Cooperage officially launched in August and immediately sold out of its miniature barrels, which are crafted from retired commercial casks that no longer age spirits fast enough for large-scale warehouses. According to Killian O’Mahony, these wood staves retain decades of seasoning from whiskey, scotch, or wine, allowing home enthusiasts, bars, and restaurants to age and personalize wines and spirits within days or weeks.
Chefs and cultural sites have also commissioned traditional equipment. Bunratty Castle commissioned a tumble churn for its bean an tí, and other culinary professionals utilize tumble churns to produce fresh butter for guests, reflecting a broader consumer return to items made by human hands.
Frequently Asked Questions
What is the difference between white coopering and wet coopering?
According to Killian O’Mahony, wet coopering builds casks to keep liquids securely inside for brewing and distilling, while white coopering constructs household vessels like tankards, tubs, pails, and butter churns.
Why are butter churns made from maple instead of oak?
Maple is selected for butter churns because its natural antimicrobial properties provide a food-safe surface that does not impart unwanted flavors, whereas oak is used when flavor transfer is desired, according to Killian O’Mahony.
Can miniature barrels be customized for home use?
Yes. The cooperage produces custom casks from various woods—including French oak and sherry-seasoned timber—to allow individuals and private whiskey clubs to age and personalize their own spirits.
