Planalto is today one of the biggest references for white wine in the Douro Demarcated Region, the result of in-depth studies carried out over the years, the careful choice of grape varieties that compose it and the use of the best winemaking technology in its production. Grapes from selected varieties from the highlands of the Douro region. In these high altitude areas, grapes with the desired ripeness and acidity are chosen for this type of wine. After gentle de-stemming, the grapes are pressed, followed by decantation at low temperature with strict oenological control. Once the necessary clarity is obtained, long alcoholic fermentation follows at a controlled temperature between 16ºC and 18ºC. The wines are stored at the Vila Real Winery, separated by grape variety or vineyard.
