ST. PAUL, Minn. -- After nearly 150 years, the last old-line brewery in the Twin Cities closed its doors Monday.

Minnesota Brewing Company filed for bankruptcy protection in February.

Its chief brand, Grain Belt Premium, will live on only if another regional brewer buys it or agrees to make it under a production contract. The company also makes Pig's Eye beer.

The brewery had 120 employees, but with its bottling line operating under a leaky roof, those overseeing the bankruptcy reorganization have given up hope for a turnaround.

Company spokeswoman Lisa Nasseff said a piecemeal liquidation is likely.

The first beer was made on the site in 1855 by German settlers. The shutdown came four years and nine months after the historic Stroh Brewery was suddenly closed on St. Paul's east side.

Brewery president Jack Lee said in February that the company asked the city of St. Paul for a $2 million guarantee that would have prevented the bankruptcy filing.
