A-B InBev agreed to buy Elysian in February

The head brewer of craft brewer Elysian has left the company days after it was fully acquired by Anheuser-Busch InBev.

Dick Cantwell, one of the three founders of the Seattle brewer, said in a statement this week that he leaves Elysian "in good hands". He also said he would not rule out working with A-B InBev in the future.

"Now it's time to move into the next phase of my life, pursuing my passion to help both the craft industry and other brewers achieve their dreams," Cantwell said.

However, the Washington Beer Blog reported on Monday that Cantwell was more scathing of his former owners and colleagues in an email.

"The tenor of the deal, mainly from the point of view of my former partners and me, was such that I can’t possibly work with them into a future of any duration. My concerns were never even considered as a factor of whether we should or shouldn’t. From the start it was me against everyone else, with no regrets expressed," Cantwell reportedly wrote.

He said A-B InBev had treated him with "consideration and seriousness" but that he had decided he can't work with them.

"I am a craft brewer, past, present and future, no matter what I end up doing," Cantwell reportedly added.

A-B InBev agreed to buy Elysian in February, with the deal closing at the end of last month. The firm is one of a selection of craft brewers A-B InBev has purchased in the past two years.
