The story of the brewery began in 1545. The Roman family's brewery is located in Mater, east of the city of Oudenaarde. The village, which is now part of Oudenaarde, as well as the family name, probably find their origins back in the Roman ages. in those days, the brewery was located along a major road connecting Germany to France. Along this commercial route, there was a halt place called "De Clocke", in which travelers were able to rest and spend the night. They could rest their horses, get them stabled or get a fresh horse if necessary. This stagecoach in an inn, a farm, a mill, a malt house, as well as a brewery of course.

After 1945, the focus was put on rebuilding ther former market, and the bottom-fermented beer Romy Pils was created to complete the product range. Thank to the production of Romy Pils, the turnover increased dramatically and the brewery went through a new period of expansion.

1990 was the year of the succesful launch of the Ename abbey beers: Ename Double and Ename Triple. This range of abbey beers was reinforced by the Ename Blond (1997) and the amber-red winter version Ename Cuvée 974 (2002). This beer replaced the Christmas Bell that had lost popularity. The Mater Witbier (white beer) was put on the market in 1993.
