Trincadeira, sometimes called Trincadeira Preta, or black Trincadeira, is a red grape highly valued by winemakers in southern portugal and grown on a total of 11,674 ha/28,835 acres of vineyard all over the country. Known in the douro as tinta amarela, it is very susceptible to rot and therefore only performs well in the driest of climates. Trincadeira is therefore ideally suited to the alentejo, where it can produce deep-coloured, spicy wines in the right conditions but tends to herbaceousness if not picked at the right time.
