Sercialinho is a Portuguese grape variety created in the 1950s at the Alcobaça research center in Bairrada. For some time, it was believed to be a cross of Sercial and Alvarinho, but ti was most likely created as a cross of Uva Cão and Vital.
The grape is rare and mostly used in blends, providing freshness and a bright, fruity aroma. It is rarely used as a varietal, but some producers have created interesting varietal examples, proving that the grape could have more potential. The wines are crisp and aromatic, usually high in acidity and alcohol, while the aroma is reminiscent of green apples and pears, sometimes with a touch of honey.
