I got to try Cool Taste Apple-Flavored Jelly Drink just now. I thought it would be similar to jelly drinks sold in plastic bottles but I got disappointed.
The taste is okay. The juice itself is sweet, like a typical tetrapack juice. The green jelly is only slightly sweet, not bad.
There is very little juice though, not enough to quench your thirst. Another problem is that the packaging is a poor idea for this kind of product. The jelly is not cut into small pieces and since the straw offers only a small opening, getting the jelly out is difficult. You will have to suck and suck while mashing the container, then you will give up, get a scissor, and just cut the upper half of the pack to get the remaining mass of jelly inside.
