Cathair Dia Brewing Company

Cathair Dia Brewing Company, also known as Cathairian Brewing Co. is a notable producer of alcoholic beverages, particularly beer, mead, and whiskey, among others. The company is known as one of the first well-established breweries to solely exist to brew and sell beer and is one of the oldest in Radorah. Located on Eglaise Street near the western wall of the city, the establishment is based out of three separate buildings at the end of the street, with separate structures for both the brewery and distillery.

Despite the smaller sizes of the batches produced in compared to other major breweries, Cathair Dia is one of the best profiting businesses in its trade.

The company was established by two brothers, Walsh and Roterius Yungenheim, the latter of which was a monk at the Cathedral of Baltora. Together, the brothers ran a small apiary just to the north of the city and found it difficult to come by profits from their products, which resulted in their attempt to venture into the production of beeswax and mead, the latter being much more successful. In or around 1011, the brothers managed to secure a large loan from the Ryvenport Bank, and with it purchased a recently closed crematorium, which they re-purposed into their first established brewery, opening the service to the public in 1014.
