Pillitteri Estates Winery is proud to produce one of nature's most exquisite gifts. Icewine. Harvest of the Icewine grapes occurs when temperatures have reached -8 C or colder. When pressed, these hand picked, naturally frozen grapes yield a juice with an intense concentration of sugars, acids, flavours and aromas.The transformation of the grapes while hanging on the vine awaiting their winter harvest date is nothing short of magical. As the grapes slowly evolve from a simple green to a beautiful golden colour, the flavour becomes much more golden as well since the flavour intensifies, the complexity increases and the quality escalates. It is a process that only Mother Nature can accomplish in her own special way.
