Tejo Wines, representing Portugal’s central Tejo region, has announced the official recognition of a fourth terroir within the area. 

Following an in-depth soil study, the new terroir, Serras, joins the already recognised trio of Bairro, Campo and Charneca. 

Translating to “mountains” in English, Serras reflects the mountainous nature of the landscape, with vineyards planted on slopes and plateaus. It has a higher average altitude of 232m compared to the other terroirs in the region. 

According to Tejo Wines, the higher-altitude conditions create a cooler and more humid climate, with greater diurnal temperature variation and above-average rainfall. These factors contribute to slower grape ripening and help reinforce the freshness and balance of the wines. 

Covering 375ha, Serras is also home to some of the oldest vineyards in Tejo, with an average planting year of 1978. 

The announcement comes as global interest in old vines grows and follows other recent updates in the region, including an amendment to the PGI to recognise low and no alcohol wines. 

Luis de Castro, president of the CVR Tejo, said: “We’re delighted to be able to make this important announcement ahead of the Wines of Portugal tasting next week.  

“The new Serras terroir reflects Tejo’s commitment to innovation, sustainability and diversity, while staying true to our rich and authentic winemaking heritage.   

“Serras has a big impact on the wines, contributing elegance and minerality, good structure and vibrant natural acidity, and consequently a strong ageing potential. 

“From relative obscurity to rising star, Tejo is now increasingly on the global wine agenda as a source of distinctive styles with alluring freshness and exceptional value at all price points.”
