Ireland enjoys international recognition for its exceptional beer and whiskey, but every great pint and fine spirit begins with one essential ingredient: malted barley. At the centre of this story stands The Malting Company of Ireland (MCI), a heritage Irish malting company that has crafted premium Irish malt for brewers and distillers for over 160 years.
Founded in 1858 and based in Cork, MCI remains Ireland’s only Irish-owned malting company. The company supplies high-quality malted barley made exclusively from Irish-grown barley. By combining generations of malting expertise with modern processing technology, MCI delivers reliable, flavour-driven malts that breweries and distilleries trust across Ireland and around the world.
Rooted in Irish agriculture and supported by farmer-owned co-operatives, The Malting Company of Ireland embodies authenticity, traceability, and a deep connection to Ireland’s brewing and distilling heritage.
A Proud Irish Malting Heritage Since 1858
The history of The Malting Company of Ireland runs parallel to the evolution of Irish brewing and distilling. Since 1858, the company has supplied malted barley to generations of Irish brewers and whiskey makers, adapting to changing styles while remaining firmly grounded in tradition.
From traditional ale and stout production to the modern resurgence of Irish craft beer and premium whiskey, MCI continues to support Ireland’s drinks industry. The company’s longevity reflects not only technical excellence but also a long-standing commitment to quality, consistency, and enduring partnerships.
Today, MCI operates as a joint venture between Tirlán and Dairygold, two of Ireland’s largest farmer-owned co-operatives. This structure keeps Irish barley farmers at the heart of the business and strengthens a truly local and sustainable supply chain for Irish malt production.
Irish Barley: The Foundation of Premium Irish Malt
Exceptional malt starts with exceptional barley, and Ireland’s climate provides ideal growing conditions for malting barley. Mild temperatures, regular rainfall, and fertile soils allow Irish barley to develop strong enzymatic potential, uniform grain size, and excellent extract efficiency.
The Malting Company of Ireland sources its barley exclusively from Irish farms and works closely with local growers to maintain strict quality standards. This close collaboration delivers full traceability from field to malt house and gives brewers and distillers confidence in both provenance and performance.
By using 100% Irish-grown barley, MCI ensures that every batch of malt reflects the character of Ireland’s land while supporting rural communities and sustainable agriculture.
The Malting Process: Where Tradition Meets Precision
Malting demands both craftsmanship and precision. At The Malting Company of Ireland, teams combine generations of hands-on experience with innovative process control to produce consistently high-quality Irish malt. From barley intake to finished malt, MCI carefully controls every stage to optimise performance, flavour, and reliability for brewers and distillers.
One distinctive feature sets MCI apart: a unique barley washing step before steeping. Before the barley enters the steeping vessels, MCI gently washes the grain using a corkscrew-style auger and water, rinsing it as it moves through the system.
This washing step removes surface dust, soil residue, loose husk material, and field debris from the barley. By cleaning the grain before steeping, MCI improves water absorption during hydration and promotes more even germination across each batch. Uniform germination plays a critical role in developing predictable enzyme levels and reliable extract performance.
The washing process also delivers clear quality and flavour benefits. Cleaner barley entering the steep reduces the risk of unwanted compounds carrying through the malting process, supporting a cleaner malt profile and greater batch-to-batch consistency. Improved steep hygiene also enhances process control, particularly for customers who prioritise efficiency, yield, and repeatability.
After washing, the barley passes through traditional steeping, germination, and kilning stages. MCI closely monitors each stage to develop the desired enzyme activity, colour, and flavour. The result is Irish malt that combines heritage craftsmanship with thoughtful innovation while preserving the natural character of Irish-grown barley.
