Kirin Holdings Co. said it is interested in raising its stake in San Miguel Brewery Inc.

Kirin, which holds about 48 percent of the Philippine beermaker, would weigh boosting its stake in the brewer if offered, President Senji Miyake said at a news conference in Tokyo on Thursday, without elaborating. San Miguel Corp. owns 51 percent of the beermaker.

Ramon Ang, the billionaire chief of San Miguel, said last month he has received several bids of as much as $6 billion for its 51 percent stake in the brewery unit, and that Kirin hasn't offered to buy the remaining stake.
