Rótulo de Cortiça – one of Adega de Borba’s ex-libris - was produced from the most typical varieties in the Alentejo region, sub-region of Borba.
Originating from old vines, the grapes were strictly controlled during the maturation process and harvested in small quantities. After the grapes de-stemming and crushing, the alcoholic fermentation began. It was performed for about 10 to 15 days at a controlled temperature of 24ºC in order to extract the greatest aromas and flavours of the grapes. To increase the poliphenolic complexity, the flavours of the tannins and the wine’s structure, the wine remained in the vat for a post-fermentative maceration process. The malolactic fermentation was then performed in stainless steel vats. In order to increase the wine’s organoleptic characteristics, it aged for 12 months in 3rd and 4th year French oak barrels and wooden barrels. Then wine then aged for another 6 months in the bottle stored in a cellar.

The white grape varieties recently introduced in Alentejo’s vine population show their greatest potential in this wine and symbolise quality in the region of Borba. Grapes cultivated in vineyards with moderate productivity levels allow us to produce a fresh and balanced wine. The harvest was performed manually during the mornings to achieve the ideal temperature of the grapes as they arrived in the winery. The grapes were transported in small quantities.

After the crushing and total destemming of the grapes a slight maceration was performed, after which the pressing, decantation through cold system for 24 hours and alcoholic fermentation followed. 30 % of the wine was then stored in French and American oak barrels at a controlled temperature of 15 ºC. After the ageing, stabilisation and slight filtration the wine was bottled.
