Barley malt syrup is a sweetener produced from sprouted barley, containing approximately 65 percent maltose, 30 percent complex carbohydrate, 3% protein. Malt syrup is dark brown, thick and sticky; and possesses a strong distinctive flavor that can only be described as "malty." It is about half as sweet as white sugar. Barley malt syrup is best used in combination with other natural sweeteners.
