Types of Wine/Grapes
The main grape varieties grown in the region are used
to make both table wines and Port. Around 90 different varieties are
permitted, of which the best are Touriga Nacional and Tinta Roriz. Gouveio,
Malvasia fina and Viosinho are the favoured white grapes.
The sweet fortified wine known as Port, evolved in the
early part of the 18th century, when a measure of brandy was added to the
region’s dry (and fairly poor quality wines) to stabilize them during
shipment abroad.
Climate/Geography
The boundaries of the Douro region correspond with an
outcrop of pre-Cambrian schist. Hemmed in by granite, this schist runs
either side of the Douro river for nearly 100 km, from the Spanish
frontier in the east to the village of Barqueiros in the west. The River
Corgo flows into the Douro near where the town of Regua splits the main
production area of DOC Porto into two: Baixo Corgo, the area around the
town is the westernmost area for port production, and also the coolest and
wettest. Cima Corgo, upstream from Regua is the heartland of top-quality
port production, centred around the town of Pinhao. Port grapes tend to
occupy the best sites on the schist soils, especially in the highlands
where the climate is a little cooler.
