McDonald’s also offers Newman’s Own Organics Blend in three iced coffee flavors in New England and Albany, NY: Hazelnut, Vanilla and Caramel.

“It has been gratifying to see consumers embrace our organic coffee, and we look forward to its continued growth,” says Nell Newman, Co-Founder and President of Newman’s Own Organics.

Larry Blanford, President and CEO of Green Mountain Coffee Roasters, Inc., says, “When we began our relationship with McDonald’s in 2005, our goal was to provide the highest quality coffee to customers in New England and Albany, NY.
