Starbucks' new Refreshers energy drinks get mixed reviews

— -- In an attempt to dip into the $8 billion dollar energy-drink market, Starbucks has rolled out a new line of "natural" energy drinks.

The fruity drink that's high in antioxidants uses unroasted, green coffee extract for the energy boost.

Last week Starbucks offered free samples of its Very Berry Hibiscus and Cool Lime Refreshers.

Marketing reporter Bruce Horovitz spoke with consumers immediately after they tasted their very first Refreshers at a Starbucks in McLean, Va.
