Donald Ziraldo is a Canadian winemaker, pioneer and founder in 1975 of Inniskillin, Ontario's first winery since Prohibition in the 1930s. Nine years later, he teamed up with Karl Kaiser, an Austrian-born Canadian winemaker, and produced the first ice wines. He left Inniskillin in 2006 to create his own estate.

Donald Ziraldo planted his Riesling vines in 2007 and adopted the principles of organic farming from the outset. He then continues with Vidal vines, a hybrid white grape variety, a cross between Trebbiano (or Ugni blanc) and Rayon d'Or, offering both a high sugar content in cold climates and a good level of acidity. The grapes are harvested between the beginning of December and March.

The Niagara Peninsula offers unique climatic conditions for the ripening of the grapes: the very cold winters naturally freeze the water contained in the berries and allow a perfect balance between acidity, sugar and aromatic richness to be achieved.
