Wine of South Eastern Australia. Pinot Grigio - White Australian Wine. In 1899 John James McWilliam won his first gold medal with a wine from the Silverwood Vineyard. Over a century later, McWilliam's proud heritage and dedication to quality is embodied by the Silverwood Range. McWilliam's Silverwood Pinot Grigio is fresh and lively with flavours of green apple and pear, soft minerality and a long, crisp finish.
