The Island Terroirs
The island of Madeira, of volcanic origin, was discovered in 1419 by the Portuguese Captain, João Gonçalves Zarco, and is an archipelago composed of two inhabited islands – Madeira and Porto Santo – and two small uninhabited islets, the Desertas and the Selvagens.
Madeira’s location in the Atlantic made it an important strategic port of call which led to the rapid expansion of the island’s wine, especially in countries such as the United States of America. It was so popular in the USA that in the 18th century, Madeira wine is reported to have represented over 75% of all wine imported into this market.
The archipelago is situated at 32º 38’ latitude north and 16º 54’ longitude west, about 1100kms off the coast of Portugal, and 590 kms off the coast of Morocco.
The total area of the island is 741 kms2, of which the vineyards occupy about 490 hectares.
The island relief is steep and a mountain range that climbs up to 1.862m (6.109Ft) in altitude above sea-level – the highest peak is Pico Ruivo – runs the length of the island, virtually dividing it in tow, and causing 7 different micro-climates that have a determining effect on where the vineyards are planted.
The overall sub-tropical and temperate climate, together with the fertile volcanic soils provide perfect conditions for the growth of a wide range of different crops.
Madeira is rich and diverse in terroirs. As a volcanic island in the middle of the Atlantic Ocean, the vineyards are exposed to the ocean breeze and the grapes from vineyards planted at lower levels can show saline and iodine notes.
The soils are acidic, rich in mineral, iron and phosphor, and poor in potassium, which all contribute to the trademark acidity of the wine. In fact, the acidity is one of the most remarkable assets of the wines, allowing this unique wine to keep fresh even after having been bottled for many years.
Irrigation is provided by an ancient system of canals called “levadas” that brings water from the mountains down to the agricultural plots, until the ocean
