Coonawarra
A cigar-shaped strip of red terra rossa over limestone in South Australia's Limestone Coast, where Cabernet Sauvignon made up 60% of the 2026 crush.
Coonawarra sits in the Limestone Coast Zone of South Australia, near the Victorian border and approximately 380 kilometres south of Adelaide. The Coonawarra Geographical Indication was entered in the Register of Protected Names on 6 January 2003, and the region has 5,784 hectares of vineyards (National Vineyard Scan 2020), 92% of them red varieties. The region is defined by a cigar-shaped strip of terra rossa resting over a limestone cap, which Parker Estate describes as 27km long and 2km wide. Wine Australia says Coonawarra is "considered to be the pre-eminent producer of Cabernet Sauvignon in Australia".

Open WineSchoolHistory & Heritage
Scottish-born gardener William Wilson chose a block on the red terra rossa around the town of Penola and advised John Riddoch, a fellow Scot who arrived in 1861, to do the same. In 1890 Riddoch divided 800 hectares of terra rossa on his land into the Coonawarra Fruit Colony, offering four-hectare allotments, and 26 colonists began planting in 1891. Coonawarra's first vintage, the Coonawarra Vineyards Claret, was produced in 1895 by Frederick Wood, and Riddoch commissioned a large tri-gabled stone winery that was completed in time for the third vintage in 1897. After 1901, the year John Riddoch (d. 1901) died, the Fruit Colony fell into financial difficulty; in 1926 the South Australian Government offered soldier settlers payments to remove their vines and establish dairy farms, leaving 120 of the original 360 hectares of vines within a few years. Bill Redman, who came to work at the Riddoch winery in 1901 at 14, established his own winery in 1908 and for many years was the sole red wine producer in the region. The modern Coonawarra dates to 1951, when Samuel Wynn and his son David purchased the former Riddoch winery and vineyards. Mildara began sourcing Coonawarra wine in 1953, Penfolds purchased 16 hectares in 1957, Lindemans bought Rouge Homme from the Redman family in 1965, and the Coonawarra Vignerons Association was formed in 1980 with Doug Balnaves as inaugural President.

Geography & Climate
Coonawarra lies in the south eastern corner of South Australia, a flat region famous for its terra rossa soils, a thin iron-oxide based top soil over limestone. Terra rossa is a type of red clay produced by the weathering of limestone and coloured by iron oxide; it averages 50 centimetres deep over a limestone base and allows water to drain freely, and the limestone aquifer provides a permanent supply of underground water. Local sources give the strip slightly different dimensions: Coonawarra Vignerons gives a length of 27 kilometres, Parker Estate gives 27km long and 2km wide, and Katnook Estate gives 2km wide and 25 km long. A maritime influence comes from upwelling of cold ocean currents at certain times of the year, with cold winters, cool summer night temperatures and consistent cloud cover; the climate is that of a temperate region influenced by maritime breezes off the Southern Ocean. Elevation ranges from 51 to 127 metres, and 2006-2025 averages give a mean January temperature of 20.6 ºC, annual rainfall of 595 mm, October to April growing season rainfall of 239 mm and 1571 growing degree days.

Coonawarra Cabernet often shows dark cherry and blackcurrant fruit with a mint note. Coonawarra Vignerons pitches the style as "the fruit purity, ripeness and concentration of Australia", and Decanter's David Sly calls mint and eucalyptus "classic Coonawarra characteristics". Wine Australia says Coonawarra is considered the pre-eminent producer of Cabernet Sauvignon in Australia, describing medium to full-bodied wines with cassis, blackberry, plum and dark cherry flavours and firm but plush tannins, while Coonawarra Vignerons adds dark red berries and violets and describes today's wines as medium bodied with silky supple tannins. Cabernet Sauvignon was 60% of the region's 2026 crush, Shiraz 21%, Merlot 7%, Chardonnay 6% and Sauvignon Blanc 3%. Up until the 1950s Shiraz was the main variety grown in Coonawarra; it tends toward a medium-bodied style with spice and raspberry-toned fruit, and blending Shiraz and Cabernet Sauvignon is a Coonawarra tradition. Merlot does not have a long tradition in Coonawarra but has been a successful blending partner for Cabernet Sauvignon. Coonawarra Vignerons adds that the region produces premium Shiraz and cool climate Riesling, and that Chardonnay, Sauvignon Blanc, Merlot and Cabernet Franc are well suited climatically. 1,8-cineole, commonly known as eucalyptol, is responsible for 'eucalypt', 'camphor' and 'minty' characters in some red wines, and Eucalyptus trees growing close to vineyards are the primary source.
- Cabernet Sauvignon: 60% of the 2026 crush; cassis, blackberry, plum and dark cherry with firm but plush tannins
- Shiraz: 21% of the 2026 crush; the main variety until the 1950s, medium-bodied with spice and raspberry-toned fruit
- Merlot: 7% of the 2026 crush; a blending partner for Cabernet Sauvignon without a long regional tradition
Notable Producers
Wynns Coonawarra Estate's vineyards date to John Riddoch's first plantings in 1891, and the estate describes them as the longest-established vineyards in the region. Its Black Label Cabernet Sauvignon was first produced in 1954 from the top 20 to 25 per cent of its Cabernet Sauvignon fruit, the John Riddoch Cabernet Sauvignon was first made in 1982, and Michael Shiraz, a one-off from the 1955 vintage, was revived with the 1990 vintage. Riddoch's second vintage was made in 1896 in the woolshed that still stands at Katnook Estate, where the first commercial vintage was made in 1980 by winemaker Wayne Stehbens; Daniel McNicol is now at the helm of its winemaking, and the estate covers 155 hectares. Ian and Wendy Hollick established Hollick Wines in 1983, John and Faye Parker established Parker Coonawarra Estate, and Parker Estate released its first vintage of First Growth in 1988; its winemaking team is led by Andrew Hardy. The Lynn family planted 6 acres of Shiraz on the Majella property in 1968 and sold their first grapes to Wynns Coonawarra Estate in 1980, and Majella's first vintage, in 1991, was 10 tonnes of Shiraz. The Balnaves of Coonawarra vineyard was established in 1975, and the first wines under the Balnaves of Coonawarra label were produced in 1990. Penfolds purchased 16 hectares in Coonawarra in 1957, and its Coonawarra range includes Bin 128 Coonawarra Shiraz and Bin 169 Coonawarra Cabernet Sauvignon.

Wine Laws & Classification
The Geographical Indication Coonawarra is located within the Limestone Coast zone of South Australia. It was entered in the Register of Protected Names on 6 January 2003 in response to a direction from the Presiding Member of the Geographical Indications Committee, and the textual description of the boundary is the legal definition. A debate over where to draw the line followed Australia's move to an appellation system with defined geographical boundaries, with Coonawarra's reputation, land values and grape and wine prices at stake; the boundary was settled in the Federal Court in 2003 after 7 years of debate, slightly expanding it to the north, south and east to accommodate vineyards on established terra rossa soil. Under the blending rules, a GI label claim requires a minimum of 85% of the wine to come from that GI, and compliance with the blending rules is monitored through the Label Integrity Program. Coonawarra Grape and Wine Incorporated, trading as Coonawarra Vignerons, is an amalgamation of the former Coonawarra Vignerons Association and the Coonawarra Grapegrowers Association and officially came into being in December 2013.

Coonawarra lies approximately 380km south of Adelaide and 427km west of Melbourne, and the Coonawarra Strip is home to more than 25 cellar doors. The region was officially named Coonawarra in 1897, a name believed to derive from the Pinechunga/Boandik word for swan and previously thought to mean honeysuckle, and Coonawarra Vignerons acknowledges the Pinechunga people as the traditional custodians of the land. Coonawarra Vignerons bills Coonawarra Cabernet Celebrations, held each October, as a month long wine festival; the 2026 edition runs 1 to 18 October with over 40 free and ticketed tastings and events. Other fixtures on the region's calendar include the Coonawarra Vignerons Cup at Penola Racecourse in January, the Penola Coonawarra Arts Festival in May, and Coonawarra Cellar Dwellers in July, when wineries offer back vintage, cellared wines to taste and buy. Naracoorte and Mount Gambier are both within 30 minutes drive of Penola and Coonawarra, and the seaside towns of Robe, Beachport, Kingston and Port McDonnell are options for a coastal stay.

Get the DeckCoonawarra Cabernet Sauvignon is the region's signature red style. The fruit profile centres on blackcurrant and dark cherry framed by the eucalyptus-mint character associated with the region, with cedar notes from French oak maturation and graphite noted on some estate wines. Tannins are fine grained and firmly structured, and acidity is high by warm-climate-Australian standards thanks to the maritime cool air and long ripening season. With bottle age the wines develop leather, dried herbs, tobacco, and forest-floor notes. Coonawarra Shiraz shows spice and raspberry-toned fruit in a medium-bodied frame. Cabernet-Shiraz blends combine the structural backbone of Cabernet with Shiraz's mid-palate generosity in a long-standing Coonawarra blending tradition.
- Wynns Coonawarra Estate Black Label Cabernet SauvignonFirst produced in 1954 from only the top 20 to 25 per cent of Cabernet Sauvignon fruit grown in Wynns' terra rossa vineyards; the 2024 is its 69th vintage, made in a medium bodied style.
