Vinification of Vinha D Ervideira Selected Harvest White Wine: The process occurs variety by variety. The Antão Vaz grapes are de-stemmed, lightly crushed and vacuum pressed. After defecation, they ferment at a controlled temperature between 13 and 15ºC. The Arinto grapes are de-stemmed and sent, without crushing, to “vinimatics”, for skin maceration between 6 and 10 hours. They are then pressed and sent to the cold room, where they ferment at between 13 and 15ºC.
