Diageo decided to close the plant on Commonwealth Drive after a strategic review of its supply operations, according to a statement issued by the company.
The closure is a blow to the 128 union workers and approximate 20 non-union workers who have tried to find solutions to keep the plant open, said Fred Pecker, secretary-treasurer of International Longshore and Warehouse Union Local 6.
A total of 53 of the union workers have been there more than 20 years, and 18 of those have been there more than 34 years, he said.
"We have a lot of people who've spent a lifetime in that plant," Mr. Pecker said. "A lot of these people were planning on retiring, and now they have to go out and look for jobs."
