Coonawarra is located on the limestone coast of South Australia (Limestone Coast), and is famous for producing high-quality red wine. On the northwest side is the Benson Mountain (Mount Benson) area near the sea, and on the north side is the Ladunbury (Wrattonbully) area. Kunawara has the red soil unique to the limestone coast. The region is Mediterranean, the southern ocean has a cooling effect on the climate, and the vineyards generally need irrigation because of the low rainfall in the vineyards during the vine growth period. The Cabernet Sauvignon (Cabernet sauvignon) varieties of wine produced in the region have been known to the world; they have aromas of blackcurrant, mint and cedar, and their taste is extremely balanced and the tannins are very fine. Shiraz varieties of Kunawara are generally aromatic with raspberry and black pepper. Riesling, a small producer, has a long history of brewing. In addition, there are also wines in the region made with Cabernet Sauvignon, Merlot, Malbec and Tasteful (Petit Verdot), which are also unique wine types in Australia. Before entering South Australia, there is a big sign of Australia's "quarantine department restrictions" on the roadside. You must still carry fresh fruits and vegetables in the garbage bin ahead, and the offenders will be fined up to AUD 2000. As a result, we stood by the garbage bin and ate all the fruits we brought, saving lunch. Port Elliot is one of South Australia’s most cozy beach areas and a popular tourist destination. Port Elliot is a modern seaside village with cafes, antiques and gift shops along The Strand.
