Porongurups, Mount Barker, Albany, Denmark and Frankland River
Soil conditions
The main soils are similar to that of the Margaret River (wine region); lateritic gravelly sandy loams (marri country) or sandy loams from granite and gneissic bedrocks. Typically brown to grey-brown in color, with the percentage of clay varying from one location to another.[1]
The Great Southern wine region is in Western Australia's Great Southern region. It comprises an area 200 kilometres (120 mi) from east to west and over 100 kilometres (62 mi) from north to south, and is Australia's largest wine region.
Albany is a subregion of the Great Southern region of Western Australia. Albany's climate is maritime, strongly shaped and moderated by the Southern Ocean; the standard description is that it is Mediterranean, with moist, cool winters and warm, dry summers. Diurnal temperature range is minimal, and moderate humidity in summer assists ripening by reducing stress on the vines. Soil types of the region are either lateritic gravelly, sandy loams or sandy loams derived directly from granite and gneissic rocks.[1][4]
Denmark the coastal neighbour of Albany is one of the five subregions of Great Southern. Marginally wetter and cooler than Albany, although the differences are not of significant magnitude. The climate is broadly similar to Albany; the varieties being grown and the wine styles are also similar.[1][4]
Frankland River is one of the five subregions of the Great Southern in Western Australia. It is situated in the northwestern corner of the region, its western boundary touching the eastern side of Manjimup. It is the most northerly, inland subregion of Great Southern, still Mediterranean in terms of dominant winter-spring rainfall, but with greater continentality. The soils are chiefly derived from lateritic gravelly sandy loams or sandy loams derived from granite or gneissic rocks, and so are typically rich, red in colour and of uniform depth with some areas carrying marri and karri loams. The climatic influences for the area favor medium-bodied, Bordeaux style red varieties, and with the excellent adaptation of slightly earlier-maturing Shiraz.[1][4]
Mount Barker this cool subregion is generally regarded as the most important subregion of the Great Southern. Ripening month and average temperatures in the established Mount Barker vineyards are significantly lower than in the Médoc, and significantly lower than in the lower warmer Bordeaux appellations such as Saint Emilion and Pomerol. Average ripening period sunshine hours at Mount Barker together with the whole season measure of sunshine hours are nearly identical with those of Bordeaux.[3][6][7] Situated in the middle of the Great Southern, with strong continental aspects together with marri soils and lateritic gravely and sandy loams provided from the granite rock backdrop the region is suited to Riesling, Shiraz, Cabernet Sauvignon, and Pinot noir.[1][4][8]
Porongurup is the fifth of the subregions of the Great Southern, just east of Mount Barker; and especially, the slopes facing north and north-east. The Porongorups are a small, isolated range of intrusive granite, of which slopes enjoy outstanding air drainage.[1] The Porongorups ranges has one of the richest concentrations of plant species worldwide and is one of only 34 internationally significant hotspots for biodiversity.[9] The Porongurup range is one of the oldest mountain ranges in the world, dating roughly around 1.1 to 1.4 billion years old which places its formation in the ‘Proterozoic’ Eon. It owes its formation to the massive tectonic forces that have shaped the southern and western coasts of Australia, a likely result of a collision between the Australian and Antarctic landmasses.[10][11][12] The climate is Mediterranean with cool to mild winters and warm, sunny summers. While conditions are cooler and more humid higher up in the ranges with occasional snow on the taller peaks for short periods during winter and spring.[13] The soils are ancient, deep karri loams derived from weathered granite.[4][14] Porongurup is strongly indicated for all high quality white wine varieties such as Riesling, Traminer, Chardonnay, and red wine varieties such as Pinot noir, and Pinot Meunier.[1]
The international definition and recognition of this area as a distinct and unique wine growing area goes back to 1859, when original settler George Egerton-Warburton planted vines on his St Werburgh's property near Mount Barker and bottled his first vintage two years later. However, the first real commercial foundations were laid in the late 1930s by horticulturalist Bill Jamieson. His extensive knowledge of the area's soils and climate was augmented by the research of Californian Professor Harold Olmo in 1955 during a government-sponsored trip to Western Australia. Olmo spent eight months in Western Australia at the invitation of the Western Australian Vine Fruits Research Trust, while on leave from his post as Professor of Viticulture at the University of California.[1] When he published his report in 1956, one of the recommendations put forward was that Mount Barker and the Frankland area of Western Australia showed great promise for making table wines in the light traditional European style. This was further backed up by agricultural and viticultural scientist Dr John Gladstones in 1963, and endorsed by the Western Australian Grape Industry Committee (1964).
A year later, Jamieson and Houghton's celebrated winemaker Jack Mann, went to Mount Barker and the first experimental cuttings were planted in 1965 at Forest Hill.[1][14][15]
