Madeira

Madeira is a fortified wine made on the Portuguese island of Madeira, in the North Atlantic Ocean. Madeira is produced in a variety of styles ranging from dry wines which can be consumed on their own, as an apéritif, to sweet wines usually consumed with dessert. Cheaper cooking versions are often flavoured with salt and pepper for use in cooking, but these are not fit for consumption as a beverage. The islands of Madeira have a long winemaking history, dating back to the Age of Exploration , when Madeira was a standard port of call for ships heading to the New World or East Indies. To prevent the wine from spoiling, the local vintners began adding neutral grape spirits. On the long sea voyages, the wine would be exposed to excessive heat and movement, which benefited its flavour. This was discovered when an unsold shipment of wine was returned to the islands after a round trip.[citation needed]
