The Tejo river is omnipresent all over the landscape, the main responsible for the clime, the soil and, therefore, the fertility of the region. Ribatejo has a Mediterranean climate, yet suffering the influence of the river, therefore the seasons are mild.

The legislation for the region is somewhat restricted and allowed the introduction of Portuguese and foreign varieties. The red DOC wines of Ribatejo come not only from traditional varieties of the region (Trincadeira or Castelão) but also other noble varieties such as Touriga Nacional, Cabernet Sauvignon or Merlot. The most widely planted white grape variety in the region is Fernão Pires, being practically indispensable in the production of white wines in Ribatejo. Sometimes, it is packed with other varieties typical of the region, as Arinto, Tália, Trincadeira das Pratas, Vital or the international Chardonnay.

Regardless of the DOC designation or Regional, the terroir of Ribatejo is felt in any wine of the region: very fruity white wines, with tropical or floral aromas, and young reds, aromatic and of soft tannins.
