All our white and milk chocolates contain milk products. The 70% pure chocolate bar is basically vegan (i.e. lactose free), but there is a minimal chance that there is milk or protein in the bar. Our milk bars and vegan dark bars are made in the same place, where after the production of milk bars a "transition batch" is first turned to remove any remaining chocolate before dark bars are made (and vice versa). In this way, some traces may remain on the factory line. As a result, we cannot 100% guarantee that there is nothing in it. On the back of the wrapper we also mention that it may contain traces of milk (this includes lactose).
