Tawny Ports are red wines that age in wooden casks and show different shades depending on their age. Colours may vary between intense red gradually mellowing to a golden-brown colour. With time "in-wood”, Tawnys also increase in aromatic complexity, intensifying the aromas of dried fruits (walnuts and almonds), wood, coffee and chocolate, amongst others. The most common references are Tawnys with Indication of Age and Colheitas. A Tawny Port always represents a blend of several batches, with different lengths of time in casks, and whose age average (10, 20, 30 and 40 years) stated on the label, grants that lot its special and unique characteristics..
