Most of the Casa de Sabicos wines age in French or Portuguese oak barrels (6 to 18 months) and in bottles (for different time periods depending on the wine, which can go up to several years) in a chamber with a controlled constant temperature.

​

The grape varieties used are the family's traditional ones and the ones normally used in Alentejo wines. The main red grapes are Trincadeira, Aragonez, Alfrocheiro, Castelão, Alicante Bouschet, and Touriga Nacional; as for the white ones: Arinto, Antão Vaz, and Síria.

​

In the most recent vineyards some of the so-called ‘international varieties can also be found, such as Cabernet Sauvignon and Syrah (red grapes), and Chardonnay (white grapes).

​

Some wines of Casa de Sabicos are produced in very small quantities, when and only in years of absolutely exceptional maturation. Avó Sabica is one of them.

​

Joaquim Madeira, Avó Sabica’s great-grandson, is the oenologist and winemaker of Casa de Sabicos and is simultaneously responsible for the vineyards. The outstanding and distinctive characteristics of the Casa de Sabicos wines are the result of his unique experience in viticulture and winemaking.

​

The wisdom accumulated over the years, coupled with strict levels of control throughout the winemaking process, contributes to the production of unique and high-quality wines.
