Grapes: Bical, Cercial, Maria Gomes, and Sercialinho

Joao Pato's (for which the winery is named) granddaughter, Maria, started the Duckman label to highlight the indigenous varietals of Bairrada, Portugal

From 3 hectares of 20 year old vines planted to chalky-clay soils and sandy soils. The grapes are hand-harvested between early and mid September, de-stemmed with spontaneous fermentation in chestnut and French oak with ambient yeasts lasting three weeks with temperature control. The wine spends six months on lees with stirring and aged casks (50%) and stainless steel (50%) for six months.
