That's the goal behind Uzuri African Blend, Peet's Coffee & Tea's first new permanent coffee blend in eight years. With the help of nonprofit TechnoServe, Peet's coffee buyers have been training 6,000 farmers in Kenya, Tanzania and Rwanda to improve their harvesting and processing techniques for the beans that go into Uzuri (Peet's then pays them an estimated 30 percent more than they would normally get). The ultimate goal: to train and improve the lives of some 180,000 East African farmers. Starting March 3, Peet's will sell Uzuri through its coffeehouses and at Peets.com; and for a limited time through March 31, it will be available nationwide at Whole Foods Market, Wegman's and Safeway.
