very sour

extreme sour is saying it mild for these i think. my son brought these home and said him and his buddy tried to put a bunch in their mouth and couldnt do it.

sweet and sour

Grew up purchasing air heads from the variety store every time!, I love the xtreme sour candy it can go from sweet to sour really quick but I will always go back to the original airheads.

I would highly recommend thus.

This candy is so yummy. Its sweet and sour but to me more sweet. I have to hide it from the kids. Its also a very reasonable price. Good for on the run treats.
