Portia Valley Wines is owned and operated by the Grigoriou family. With company owned vineyards nestled at the top of the Monash Valley and on the fertile soils of Loveday in the Riverland, Portia Valley Wines have encapsulated the traditional taste of South Australia for local, and travelling wine enthusiasts to indulge.

Chris is a third generation viticulturist and wine producer with over 40 years’ experience in the industry. After several decades working in Riverland wineries, Chris started Portia Valley Wines along with his wife, Teresa, in 2006. Chris’s passion was always to establish a wine company to continue both his father’s and grandfather’s family legacy.


Portia Valley Wines’ long-standing reputation has been built by consistently sourcing and producing the highest-quality products. We achieve this by utilising produce from some of Australia’s most renowned grape-growing regions, and refining our proficiencies. Our holistic process encompasses every stage–from harvest, right through to bottling and export. Alongisde our dedicated sales and export team, a member of the Grigoriou family is present every step of the way to ensure the finished product is made and packaged to our standards, and delivered efficiently. Our customers can trust that every bottle of wine they purchase is worth it’s weight in value, because we sell more than just wine—we sell an unrivalled experience.


The naming of Portia Valley is representative of Chris Grigoriou’s family history in wine making. It’s a combination of his mother’s name, Portia, and the location of the first vineyard where she spent long days working at the top of Monash Valley—which overlooked the region and township. The viticulture skills and processes originated from the Peloponnese wine region of Sparta, where Chris’s Grandfather taught his family how to grow and maintain grapes. Chris’s father owned and operated a winery in Monash, which is where Chris spent his formative years learning the wine business. The skills and passion he accrued from his grandfather continue to run down the family line to bring a taste of tradition that tells the family story.
