LOCATION

McLaren Vale is located 45 minutes south of Adelaide - the capital of South Australia, Australia.

The official McLaren Vale Geographical Indication (GI) declaration was made in 1997. It captures an area from Hallett Cove, across to Clarendon, and then roughly south then south-west along the ridge of the foothills until it meets the coast at Sellicks Beach.

The official textual description of the McLaren Vale GI can be found on the Wine Australia website visit www.wineaustralia.com

A BRIEF HISTORY

McLaren Vale's extensive natural and cultural heritage spans over thousands of years of traditional ownership by the Kaura people and recently, has been shaped by European colonisation.

The colony of South Australia was founded in 1836 and McLaren Vale was established two years after following a survey conducted by John McLaren.

John Reynell and Thomas Hardy planted grape vines in 1838 and the Seaview and Hardy wineries were in operation as early as 1850.

At that time, McLaren Vale wineries made heavy, dry table wines in the style required by the bulk wine merchants and exporters of the 19th century. By the turn of the 20th century there was a shift towards making fortified wines.

Between 1920 and 1930, exports trebled and finally, after World War II, local sales increased. In the 1950s, several McLaren Vale wineries began bottling small parcels of selected wines and established cellar door tastings and sales.

In the same period, many Italian migrants settled in McLaren Vale and introduced olive and olive oil production. More recently, the production of almonds, cheese, milk and cream have added to the rich food tapestry of our region.

It was not until the 1970s that table wine grew in popularity and within the same decade, over 25 new wineries were established in our region which specialised in the production of distinctive Shiraz, Cabernet and Grenache.

Today, McLaren Vale is host to more than 80 cellar doors and our region's wines and their makers continue to receive awards and major trophies at the most prestigious wine shows in the world.

PRODUCTION AND WINEMAKING

McLaren Vale has produced wine since 1838. With more than 178 years of experience, our region reputation is strongly established in South Australia and Australia's winemaking origins.

Today, our region remains Phylloxera free and is known for innovative viticultural and winemaking techniques and an international reputation for producing the trilogy of Australian reds:Shiraz,Cabernet Sauvignon and Grenache.

Of our region's 7,412 hectares of area under vine, 54% of our plantings are dedicated to Shiraz, however our region also excels in producing exceptional Mediterranean alternative red and white varieties including Fiano, Vermentino, Barbera, Montepulciano,Nero d'Avola and Tempranillo

McLaren Vale is also home to a significant number of boutique brewers and passionate distillers and our region's reputation continues to grow steadily.

KEY VARIETIES

Shiraz

The crown jewel of McLaren Vale is Shiraz. It produces a densely coloured, richly flavoured wine that quickly develops a velvety texture. McLaren Vale Shiraz is known the world over for its quality and its seductive style.

Cabernet Sauvignon

The wines are full bodied and rich, often with a touch of dark chocolate intermixed with blackcurrant. The tannins are plentiful but soft, and the wines have structure for aging.

Grenache

This variety has enjoyed a spirited renaissance during the last decade. The older plantings produce incredibly richly flavoured wines with juiciness. One would be hard pressed to find a variety more ideally suited to McLaren Vale than Grenache and many old-vine vineyards still exist.

Mataro (Mourvedre)

Has a long history in the region although few old vine plantings remain. Interest in this variety has certainly increased in recent times due to its ability to withstand dry, warm conditions.

Chardonnay

Chardonnay established a dominance in white grape plantings with virtually every producer having a Chardonnay however in more recent years winemakers have shifted their focus to Spanish and Italian varieties better suited to the maritime climate.

Mediterranean varieties

The diversity of so called ‘Mediterranean varieties’ continues to grow with considerable excitement around varieties such as Vermentino, Barbera, Montepulciano, Fiano, Nero d’Avola, Tempranillo and Zinfandel.

McLaren Vale inherently produces wines of ample concentration and flavour; however greater restraint and terroir translucency are good terms to describe the current winemaking trend.

VINTAGE

Harvest in McLaren Vale can begin as early as late January/early February in early ripening varieties such as Chardonnay, Vermentino and Fiano and is usually completed by the end of April.

Temperatures are adequate to reliably ripen all varieties in almost all areas of the region. Rainfall and heat are the climatic factors most likely to impact harvest. As a general rule, harvest dates get later in a north-easterly direction travelling from Aldinga through to Blewitt Springs.

GEOLOGY AND SOIL

McLaren Vale is one of the most geologically diverse regions in the world.

More than 40 unique geologies are present in our region and vary in age from 15,000 years to over 550 million years.

The Geology of the McLaren Vale Wine Region map was developed as a result of decades of diligent investigation by curious geological scholars and provides a key to the complex, constantly unfolding links between geology and modern wine flavours.

Prepared by Geologists Bill Fairburn, Jeff Olliver and Wolfgang Preiss of Primary Industries and Resources South Australia (PIRSA), together with wine writer Philip White, the map was published in 2010, titled Geology of the McLaren Vale Wine Region.

Ongoing study of our region's geology provides a key to the complex, constantly unfolding links between geology and regional wine varietals and flavours, whilst the map continues to assists viticulturists in appropriate planting.

There is a wide variety of soil types, a reflection of the varied terrain; red brown sandy loams, grey brown loamy sands with yellow clay subsoils interspersed with lime, distinctly sandy soils and patches of red or black friable loams are all to be found.As the long-standing and intensive viticulture of our region attests, the soils and geography of McLaren Vale are well suited to grapegrowing.

McLaren Vale is at the forefront of best practice in terms of soil surveying and as such this diversity is well respected, with a dedicated group of our region's growers, wine makers and geographers forming a committee to explore these differences in greater detail.

Geology pits have been excavated throughout the region to showcase this unique geology, and to further highlight the relationship between geology and the region’s fine wine.

CLIMATE

McLaren Vale’s climate is Mediterranean and characterised by warm summers, moderate winters, winter-dominated rainfall, low relative humidity and relatively high evaporation.

McLaren Vale is roughly triangular in shape and bordered on three sides. Adelaide to the north, the Mt Lofty Ranges to the east and south, and the Gulf St Vincent to the west.

The proximity of Mt Lofty and the Gulf of St Vincent play a very important role in moderating the climate of our region and are largely responsible for many of the meso and micro climatic differences.

Elevation in our region peaks at 350 metres along the Sellicks foothills and Chandlers Hill, with majority of vineyards located on gently undulating to flat land between 50m and 150m.

Wind is a significant factor within McLaren Vale. There are two distinct and completely separate wind sources within our region: gully winds which blow east-west down through the foothills, and sea breezes blowing south-north up through Gulf St Vincent.

The climatic diversity of McLaren Vale has helped producers successfully embrace Spanish and Italian varieties such as Barbera, Fiano, Tempranillo,Mouvedre and Moscato and explore re-emerging varieties like Viognier,Sangiovese, Zinfandel and Verdelho.

WATER

McLaren Vale was the the first region in Australia to declare and manage its underground water resource so that it is self-replenishing. In addition, McLaren Vale built the first and largest reclaimed water network in Australia so that 100% of all irrigation used in our region is now from a sustainable resource other than river water.

There are three main sources of water in McLaren Vale which are important to irrigated grape production. Traditionally the main sources have been groundwater aquifers in the Willunga Basin and surface catchment dams, where water is collected and stored from natural run-off. Sprinkler or flood irrigation has not been used in McLaren Vale for over 25 years.

In recent years, a third resource has been introduced: treated reclaimed water which is piped into our region from the Christies Beach Wastewater Treatment Plant and Willunga Basin Water Company in the Aldinga area.

The use of recycled water is very important to the sustainability of natural water resources as it takes significant pressure off the natural groundwater.

Uptake and use of moisture monitoring technology for making informed irrigation management decisions is a touchstone for our region.
