Madeira (a PDO) is a Portuguese fortified wine, made in the Madeira Islands, off the coast of Africa. It is made through a very unique process where the wine is oxidised through both heat and ageing. Styles range from dry through to sweet, and a variety of both red and white grapes are used. Due to the wine’s exposure to both heat and oxygen during production, Madeira is extremely shelf-stable and once opened a Madeira can last almost indefinitely.
