Here is the short history of Pepsi Blue courtesy of wikipedia:
Blue was launched in mid-2002 and discontinued in Canada and the United States in 2004, although it remains available in some other countries. Its berry flavor was the result of taste-testing over 100 flavors over a 9-month period. Designed to compete with Coca-Cola’s Vanilla Coke, the flavor of Pepsi Blue was described by Pepsi only as “berry” and described by drinkers as like blueberries or raspberries, or similar to cotton candy with a berry-like aftertaste and much more sugary and syrupy than regular cola. It was tinted using Blue 1, a highly controversial coloring agent banned in numerous countries at the time. The move to make a brightly-colored version of the flagship Pepsi brand was spurred by 2001′s introduction of Mountain Dew Code Red, which had bumped PepsiCo’s Mountain Dew division sales up 6%.
In Manila, Philippines, Pepsi Blue was sold for a limited time in late 2002 to commemorate the championship of the Ateneo Blue Eagles in the UAAP. In 2011, Pepsi released a similar product to the Pepsi Blue in Metro Manila, Philippines called “Pepsi Pinas”.
I still remember the Pepsi Blue was sold here in Philippines for a limited time but I can’t remember when. Thanks to wiki!
Recently, I am seeing Pepsi Blue again. I was very curious how it taste. Hmmm… but I already started to cut off on soft drinks. One week of regular intake will result in stomach pain, chest pain and breathing difficulty. So I tried to keep my hands away from it.
After eating dinner, my better half insisted that she wanted to have a soft drink. She requested the Pepsi Blue. I granted her request. I bought an eight ounce bottle. Then she just sipped a little and let me finished it.
The verdict: It is bland and I can’t identify its flavor. It is just my opinion however.
My batteries got empty. It never allowed me to get nicer picture.

Where did you find this??????
