Harpoon to Expand

The Harpoon Brewery plans to install two new 500-barrel unitank fermenters at its South Boston facility.

The tanks, which stand 38 feet high and weigh 28,000 pounds, are the largest tanks to be installed in the brewery’s history, twice the size of the largest tank at Harpoon now, the company said in a press release.

The new tanks, which will be used for fermenting and conditioning beer, will increase Harpoon’s brewing capacity by about 20 percent, the press release added.
