The story of Brehon Brewhouse begins centuries ago when medieval Brehon Law compelled all Irish clans to have a brewery on a public road, with a never-dry cauldron and hospitality towards weary travelers. It was quite literally the law of the land to offer strangers warmth, companionship, and a good pint of ale.
Today, Brehon Brewhouse extends that timeless spirit of generosity and good beer into the modern era. It sits on a dairy farm in the rolling green hills of County Monaghan, Ireland. In fact, it is the only brewery in all of Europe located on a working dairy farm. The farm has been in the McMahon family for ten generations and is still home to a herd of approximately 300 dairy cattle which are milked daily. The family has ties to the alcohol industry going back decades as a supplier of cream to Irish distilling legends like Jamison's and Bailey's. Opening a brewery offered a way to boost the productivity of the homestead at a time when craft brewing was taking off, and current owner Seamus McMahon decided to have a go. Sheds were converted for the brewery and a Master Brewer was hired. The strategy was to create a core lineup of classic Irish Styles complimented by a unique barrel aging program done in partnership with small craft Irish distilleries.
Seamus, often referred to as the ‘King of the Stouts’ in Ireland, has created a beautiful range of high-quality craft beer with a flavor to suit everyone’s tastes. Its diverse lineup is a delicious taste of traditional Irish ales and acclaimed barrel-aged stouts and porters, all crafted with artisanal craft devotion just as they were done centuries ago according to ancient Brehon Law. Slainte!
