So, again ! Is this one of the new marketing gimmick or does this
co-called organic chocolate

really make a different ?

Well, yes and no. Chocolate is notoriously high in pesticides, but it
generally comes from the area in which it is grown rather than from the
trees themselves.

If they certify it to be pesticide free, it might be worth something.
If they only certify they didn't use any pesticide then it is marketing.
