A new radio documentary is shining a light on the people, industry and agricultural heritage behind Ireland’s first major sugar factory, as the country marks the centenary of sugar production from Irish-grown beet
Bittersweet: The Rise & Fall of the Sugar Factory explores the history of the Carlow sugar factory, which was established 100 years ago and became an important part of the region’s industrial and agricultural landscape.
Produced by Cleverality Productions for the Carlow County Council Commemorations Committee, with support from the Department of Culture, Communications and Sport, the hour-long documentary was launched at County Carlow Museum as part of Culture Night.

Bringing together the memories of former factory employees, sugar-beet growers and local people, Bittersweet looks at the development of an early Irish food manufacturing operation and the role it played within the wider community.
The factory represented more than just a production facility. It connected local agriculture with large-scale food processing, transport, engineering, maintenance and skilled manufacturing work, creating an industrial ecosystem that supported generations of workers and growers.
The documentary explores how the factory and its workforce evolved alongside changing technology and production requirements. It also considers the impact of its eventual closure, both on those who worked there and on the wider community that had grown around the industry.
At the heart of the project are the personal stories of the people who experienced the factory first-hand. For the documentary’s producer, that connection is particularly personal, with their own grandfather having worked at the factory throughout his working life.
The project developed from an interest in those individuals and the skills, knowledge and labour that kept the manufacturing operation running for generations.
“Bittersweet is really about the people behind the factory,” the project’s producer explains. “It was a major manufacturing operation, but behind that were generations of workers, beet growers and families whose lives were connected to it.”
The documentary provides an opportunity to look back at a significant chapter in Ireland’s industrial history, while also highlighting the relationship between manufacturing and the agricultural communities that supplied it.
As Ireland reflects on 100 years of sugar production from Irish-grown beet, Bittersweet offers a record of an industry that helped shape both Carlow and the people who lived and worked there.
The full Bittersweet: The Rise & Fall of the Sugar Factory documentary is available to listen to online.
The project team is also available to discuss the documentary and the industrial and working-life stories uncovered during its production, with opportunities to speak to former factory employees and sugar-beet growers featured in the programme.
