Cassaé is a unique product in that it is produced from partially fermented grape juice blended with aged brandy spirit. The method of production is similar to that used in the Cognac region of France to produce a wine known as Pineau des Charentes.  Each year, a portion of material is put aside in French oak casks to age, establishing a solera system similar to that used for the production of fine Tawny.  Cassaé is a combintion of this aged material with some young fresh material, resulting in a complex sweet wine with a unique flavour.
