The Colares Wine region was defined in 1908, which makes the second oldest wine region in Portugal. The vineyards are planted in the dunes between the hills of Sintra and the Atlantic Ocean, form Cabo da Roca until Magoito. Colares is been connected to the wine for centuries, there are proofs that wine was produced in this region since the Roman Empire. After, in 1230, the King D. Afonso III, as a landlord, demanded the plantation of vines. The region became well known by the end of the XIX century, most precisely in 1865, when the biggest threat of wine history arrived to Europe - Phylloxera. This tiny insect, original from the American Continent, was arriving to Europe alive when trips were shortened by the introduction of steam engines in boats. The Colares' vineyards were resistant to phylloxera due to roots' deepness in the sand, 8 meters in some cases, where the insect could not reach. Everywhere in Europe, except in this region, the use of the American plant (resistant to the insect) was adopted, grafted with European grape varieties.
