BUSINESS MEMO: ORANGE JUICE WARS

The soda wars have come to breakfast. PepsiCo Inc. and the Coca-Cola Co. are using their marketing muscle to revolutionize what used to be a basic beverage -- orange juice.

Cans of frozen orange juice are out. They've been replaced by an expanding array of refrigerated varieties: With or without pulp. With or without calcium. With or without extra vitamin C. And now, variations like "Orange Passion," "Orange Banana" and "Orange Ruby Red with calcium."

Led by industry giants Tropicana, which PepsiCo acquired in 1998, and Minute Maid, a unit of Coca-Cola, sales of refrigerated OJ have been soaring over the past two to three years, especially the calcium-fortified and high-pulp varieties. Sales of frozen concentrate are down 21 percent since 1997.
