Summertime at Gloria Jean's...and the Taste is Nostalgic.

IRVINE, Calif. -- Just in time for the lazy days of summer, Gloria Jean's Gourmet Coffees announced the introduction of their new Root Beer Float Chiller, available in small, regular and large sizes July 19 through September 19.

The drink's cool, creamy taste and texture is reminiscent of the All-American childhood favorite that adults still gravitate toward, especially in hot weather.

Gloria Jean's Vice President of Marketing, Diane Hays-Hoag, remarked: "We're really excited about this unique chiller and it's summer appeal. The classic root beer float is a special part of Americana, and conjures up special memories of simple pleasures and a kicked-back, summer state of mind."
