The lady doing the presentation said that it has 35% of cane sugar.

Also behind her you see "hecho con azúcar de caña" which means "made with cane sugar".

Cane sugar is generally at least a bit refined merely to purify it (so unlike High-Frutose Corn Syrup it's not made by chemically transforming something else).

That said, it's unclear if they use unrefined sugar cane, though that stuff is a complete total pita to work with hence I doubt it's not in the least bit refined.

Mind you I looked around and the info on this is all over the place: like for example saying "no added sugars" but then a bit further it turns out it has "cane sugar", which does mean that sugars were added (as the cocoa plant doesn't produce cane sugar, that would be the sugarcane plant).

Mind you, by all indications this beats almost all North American chocolates, but that hardly a tall barrier to overcome. It's pretty common to find similar stuff in European supermarkets.
