Penfolds Winery is located in Barossa Valley, South Australia, Australia. It is the most famous and largest brewery in Australia. It is regarded as a symbol of Australian red wine and is called the noble of Australian wine industry. This is a well-known brand in Australia. The history of Penfolds Winery is full of legends. Some people say that it is actually a microcosm of the evolutionary history of European colonists' exploration, development, settlement and reproduction in Australia.

To this day, Penfolds Winery is still one of the leaders in the Australian wine industry. The purpose of the winery is to brew the best quality wine under the restriction of annual growth conditions. Penfolds started from brewing Du Jia wine, thus forming a unique winemaking philosophy of the winery. Penfolds successfully broke the traditional concept of manor wine, and winemakers collected high-quality grapes from various vineyards for blending. This innovative method has brought far-reaching influence to the Australian wine industry. American oak plays an important role in the brewing process of Penfolds, especially in the ripening process of red wine. In the new wine series, French oak has also begun to emerge. Nowadays, aging in oak barrels is an indispensable part of the wine-making process.
