A wood-aged style. Prolonged periods of ageing in wood result in loss of pigment so this is a much paler, tawny-coloured style of Port, hence the name. Although such wines may be bottled as single-vintage colheita Ports, they are usually blended as a tawny of either 10, 20, 30 or 40 years of age, each comprising a blend of wines which average out at the age declared on the label.
