The grapes to produce Pinot Noir Sibaris Gran Reserva Undurraga were hand-harvested into 12 kilogram bins to preserve the quality of the fruit. The clusters and individual Pinot Noir Sibaris Gran Reserva Undurraga grapes were sorted on selection tables and then gravity-fed into fermentation vats. The grapes were destemmed and gently crushed and then underwent a cold pre-fermentation maceration at 7°C for three to five days. The temperature was increased to 15°C and selected yeasts were used to start fermentation, which lasted five to seven days at temperatures of between 24°C and 26°C. Punching down and smooth pump-overs were used each day to gently submerge the skins in the fermenting juice in order to extract colour and volume. Post fermentation maceration took place for three to 10 days. Then the wine was matured in oak barrels for 10 months prior to being blended.
The grapes are grown in the Lomas de Leyda vineyard, situated in the Leyda Valley. The Pacific Ocean has a significant influence; the vineyard is just 13 kilometres in a direct line from the sea. During the ripening period the mornings are damp and
windy, while the afternoons and evenings are cooled by the sea breezes resulting in moderate maximum temperatures. This helps to ensure the slow and gradual ripening of the grapes, conserving the aromas and flavours in the fruit balanced by natural refreshing acidity. The vineyards are situated on gentle slopes, on soils of granitic origin, which contain varying amounts of clay.
