Go to the coonawarra wine area and visit wynn winery. From Victoria to South Australia, c212 turn to a66 (riddoch highway), and go south along the a66 road, wynn winery is on the right side of the road. The winery is large and endless to describe. The most famous of this production area is its unique natural phenomenon - red soil. The red soil is not high in altitude, shaped like a cigar, stretching 15 kilometers and about 1 km wide. It is actually an ancient coastline that evolved. This layer of red soil is rich in nutrients and easy to permeate, but very thin, only 5 to 100 cm thick. This is the most suitable soil for grape growth in Australia. There is a reception center in the winery, introducing the geology and history of the winery of coonawarra, there are souvenirs to buy, you can also taste wine. I drive, so I can only watch my friend taste it.
