The big coffee news this week included the fact that Keurig Green Mountain was being acquired for just under $14 billion by JAB Holding Co.  Just in the past few years, the company has acquired Peet’s Coffee & Tea, Caribou Coffee, Einstein Bagles, Stumptown Coffee Roasters and Intelligensia Coffee.  Bloomberg reports that the company has spent some $30 billion over the past four years on the acquisitions.  Speaking of JAB and Caribou, we noted a report that Caribou has begun testing nitro coffee at 2 of its location in the Minnesota market.
