brown rice Brown rice refers to rice that has been taken from its husk but not yet milled and polished. Each grain is still intact, with an outer coating of bran (usually a tawny-brown color, hence the term “brown rice”) and the germ too. Some unmilled or “brown” rice is not brown but red or black, because the bran is naturally colored. Brown rice takes longer to cook than milled rice and is somewhat more chewy to eat. It also has more nutrients. (See for a discussion of the nutritional value of brown rice.)
