Just unlikely. Vineyards located between 600 and 750 meters in altitude in an Alentejo where plains predominate as far as the eye can see. A unique microclimate that allows to produce very fresh wines, with a balanced acidity and lower alcohol content.


Terrenus comes to life from an unconventional terroir in Alentejo. In a region where plains predominate as far as the eye can see, our vineyards are located between 600 and 750 meters of altitude, side by side with olive trees, from which our olive oil is born, and with unusual species in Alentejo such as chestnut or cherry tree.

There are seven parcels in a total of 12.5 hectares of vineyards and all located within the geographical limit of the Serra de São Mamede Natural Park, benefiting from a unique microclimate that allows the grapes to have slower maturation, which results in very fresh wines, with balanced acidity and lower alcohol content.

“Wines that reflect the perfect balance between Land and Man in which Nature dictates the final result in the production of each nectar.”


The first two parcels, both of very old vines, were acquired by Rui Reguinga in 2004 and with another particularity: they are in the French style of clos, i.e., delimited by stone walls. Our parcels to the north have schist soils and the plots to the south are mostly granitic.

All varieties are Portuguese such as Arinto, Fernão Pires, Roupeiro, Bical, Alicante Branco, Tamarez, Malvasia Fina, Trincadeira das Pratas and Moscatel Branco in white; in reds we stand out varieties like Trincadeira, Grand Noir, Alicante Bouschet, Aragonez, Alfrocheiro, Castelão, Moreto, Tinta de Olho Branco, Corropio, Tinta Grossa or Tinta Carvalha. The average age of the vines ranges between 40 years for our Terrenus, 90 to 100 years for our Terrenus Reserve and Centennial vines for the single parcel wines.


Since the beginning of this project, we have bet on viticulture entirely in organic mode, without the use of herbicides and in a perfect symbiosis with the flora and fauna of the region. Respect for nature has always been at the root of Terrenus and, therefore, we delight to cohabit, in the heart of the Serra de São Mamede, with the griffin that flies over us with its magnificent wingspan, with the viper that rests in the sun and that can surprise the unwary or with the wild boar that leaves the marks of its night passage in our vineyards.
