Question: is demera sugar the same as brown sugar

Answer: No, Natural brown sugar, raw sugar or whole cane sugar are sugars that retain a small to large amount of the molasses from the mother liquor (the partially evaporated sugar cane juice). Based upon weight, brown cane sugar when fully refined yields up to 70% white sugar, the degree depending on how much molasses remained in the sugar crystals, which in turn is dependent upon whether the brown sugar was centrifuged or not. As there is more molasses in natural brown sugar, it contains minor nutritional value and mineral content. Some natural brown sugars have particular names and characteristics, and are sold as turbinado, demerara or raw sugar if they have been centrifuged to a large degree. Brown sugars that have been only mildly centrifuged or unrefined (non-centrifuged) retain a much higher degree of molasses and are called various names across the globe according to their country of origin: e.g. panela, rapadura, jaggery, muscovado, piloncillo, etc.
