 The taste of most of the wine world was still geared towards sweet and strong wines, and the Portuguese were seeing great success in adding brandy to make their port wines stronger.The Jerezanos began to experiment with adding brandy to Sherry and discovered that the increased alcohol content also had the effect of killing off the flor, which then made the wine oxidize more and develop into another style of wine.The merchants began to call this wine oloroso meaning "pungent".
