A popular Lincoln brewery is apparently closing its doors, months after being sued for not paying rent on time, according to court documents. 

Blue Blood Brewing Co. said in a Facebook post Thursday that the brewery had been for sale for a few weeks, and that its landlord "has unexpectedly shut our doors." 

The lawsuit, filed in March in Lancaster County Court by Robbers Cave LLC, alleges Blue Blood owes $25,590 in unpaid rent and late fees. 

Robbers Cave is seeking judgement in that amount, plus interest and other fees that accrue each month.

The minimum fixed monthly rent under the company's lease is $13,471, according to the lawsuit. 

In the lawsuit, Robbers Cave demanded Blue Blood and owner Brian Podwinski vacate the property, located near 10th and High Street, saying the proper legal notice was served. 

The case was scheduled to go before a judge again on Thursday morning. 

Requests for comment by Channel 8 Eyewitness to Blue Blood and an attorney for Robbers Cave were not immediately answered Thursday.

"We sincerely apologize to our employees who have not been given sufficient opportunity to look for new employment as we had planned while negotiating through the sale," the brewery's Facebook post stated. "We thank you, Lincoln, for eight years of friendship and support, and encourage you to visit your local taprooms and support your neighborhood businesses."
