Port Winemaking KOPKE Harvest 1987: Hand-harvested at their optimum point, the grapes are de-stemmed, crushed and vinified according to a process that is based on careful maceration with the extraction of color, tannins and aromas from the skins, complemented by permanent pumping over during fermentation. This takes place in mills, at a controlled temperature between 28-30ºC, until the desired Baumé degree is reached. At this stage, wine brandy (benefit) is added, creating a fortified wine. High quality wine, coming from a single harvest. It ages in wood for variable periods of time, never less than 7 years, and is then bottled according to market requests.
