Brown sugar is a type of sugar that has been minimally refined, retaining some of the molasses naturally present in sugarcane. This gives brown sugar a richer flavor and a slightly darker color than refined white sugar.

Brown sugar is made by boiling sugarcane juice to extract the sugar crystals. The molasses is then removed, but some of it is left behind to give brown sugar its characteristic flavor and color.

There are two main types of brown sugar: light brown sugar and dark brown sugar. Light brown sugar contains more molasses than dark brown sugar, which gives it a lighter color and a sweeter flavor. Dark brown sugar has a stronger molasses flavor and a darker color.
