Pepsi and Coke are planning to add enhanced bottled waters to their product lineup. The archrivals are increasingly fighting outside their traditional cola battleground. Pepsi's Aquafina Essentials and Coke's Dasani Nutriwater will be the newest entrants in the fortified bottled water sector in early 2002. Building on strong brand recognition, they should allow their parent companies to stay at the top. Time to market, however, will be a critical measure of success.
