This is the Boston waterfront warehouse they purchased a year later, and brewed their inaugural batch of Harpoon Ale. In the beginning, they were brewing primarily for a few local pubs and restaurants.
Once the craft brew craze really took off, they were forced to expand production capacity significantly. They added their own bottling plant and in 2000, purchased the defunct Catamount Brewery a few hours north in Windsor, Vermont.
Today, Harpoon is the 12th largest craft brewery in the United States, producing over 200,000 barrels of their dozens of different beers and ciders per year. Not bad for a band of buddies who just wanted to drink better beer.
