When we ask what is the difference between raw honey and pure honey we open a can of worms. There is so much confusion around honey labeling, and a lot of people get confused.
If bees collect a sugar solution that is not from a flower and process this it is called honeydew. As an example, bees will sometimes bite grapes and collect grape juice.
If we assume raw honey to be the honey straight from the hive, either in the comb, or strained, but not filtered, and regular honey to any of the other honey-like products on the shelf, the choice is easy.
