The pub group will run the Brains pubs on a combination of leased and management contract arrangements, continuing to trade under the Brains brand to serve its beer.
Founded in 1882, Brains was Wales’ largest domestic pub chain and runs the heritage beer brand of the same name.
Following the acquisition, Ralph Findlay, chief executive of Marston’s, said: “We have worked closely with the management team and the SA Brain family to collaborate on a mutually beneficial transaction that safeguards the future of Wales’ leading pub company.”
However, no buyer has been found for the brewery and a consultation on redundancies is due to begin next Tuesday, with around 80 jobs under threat.
Currently, it is expected brewing will move to England in the short term but there are fears for Brains’ long term survival as a brand.
