Brown sugar is made by coating crystals of sucrose with molasses. A small percentage of invert sugar may be present. The molasses gives it a delicate flavor and tasty odor. It has a moist texture with large, clear sparkling crystals. Brown sugar contains from 3.5% molasses (light brown sugar) to 6.5% molasses (dark brown sugar). Light and dark are the two most common styles of brown sugar. In general, the lighter the brown sugar, the more delicate the flavor. Very dark or old-fashioned brown sugar has a more intense molasses flavor then others.
