Premium Waters is rolling out a new 700-ml bottle size for its Water Joe caffeinated bottled water. The product is a premium purified water infused with caffeine and has no taste, the company says. The 700-ml bottle of Water Joe contains 85 milligrams of caffeine, the equivalent of a small cup of coffee or a 20-ounce soft drink, it adds. Water Joe also is packaged in 20-ounce bottles with 70 mg of caffeine and 1-liter bottles that have 120 mg of caffeine.
