Supermarkets offering booze below cost had contributed to the downfall of First Quench Retailing, which operated 1,200 Threshers, Wine Rack, The Local and Haddows stores, Swaine said.
"I think losing money on alcohol is wrong and something should be done to prevent it," he added.
"It causes a lot of problems in our industry and First Quench was particularly exposed to this.
"The supermarkets can afford to do this, but people like us and First Quench cannot."
Swaine is considering buying some of the First Quench stores in Rhythm & Booze's heartland of the north of England.
