Pepsi has unveiled its new first new bottle in 16 years, representing the first update to the brand's single-serve bottle design since 1996. The new bottle, available in 16-ounce and 20-ounce variations, is a visual expression of Pepsi's "Excitement of Now" campaign, highlighted by the swirl motif that reflects the brand's youthful spirit. Meanwhile, the etched, grip-able bottom portion of the bottle delivers a "more stimulating, tactile" interaction for thirsty consumers. The new design will roll out across the entire Pepsi trademark portfolio -- including Pepsi, Diet Pepsi, Pepsi Max and Pepsi NEXT -- starting April 16th. Check out the full image below, along with a look at the previous design.
