Some people don’t like maltitol. Stevia has a very high sweetness and so what chocolate manufacturers typically do is put some other filler in with it. So, it may say Stevia on the label but if you look at the ingredients, stevia is in very small amounts and there will be some other ingredient making up for the volume sugar normally does. eg. Monkfruit sweetened chocolates, typically also have some other sweetener or filler. We decided to stay away from this market as it is too complicated for what we do and we don’t have the facilities to keep this chocolate separated.
