We’ve been to pay a visit to Callier chocolate factory in Broc (Switzerland) and one of the most interesting things I found, is pictured below:
Dark chocolate (at least at Callier) does not contain milk. Not sure yet if this is applied to any kind of dark chocolate, but I will research upon it a bit later and let you know.
A more detailed review about the tour and more interesting facts will be caught in a review soon! 😉
