Soil Characteristics
The McLaren district has many different soil types and this contributes to the wines from the area having different terroir. The vineyards are planted on soils including fertile red-brown earths, terra rossa, rendzina, soft sands and dark cracking clays.
Each of these soil types contributes to the rich diversity of wine produced by the winemakers of the region. Overall the soils have one common trait; they are free draining which means they hold very little water. This is, in fact, an advantage, as it allows the accurate control of moisture to the vines through the use of state-of-the-art drip irrigation. Because of reliable winter rain, irrigation can be kept to low levels and manipulated to achieve the production of superior fruit.
Some soil types allow grapes to be dry-grown. Approximately 20% of the total crop is dry-grown. These dry-grown vines are renowned for small fruit size, which is sought after for the intensity of its flavour.
Most vineyards are found on gently undulating land at about 100 m above sea level. In the foothills of the Mt Lofty Ranges to the east, where there is a scattering of vineyards, elevation rises to 320 m. In the north around Blewitt Springs elevation is around 200 m. These variations in elevation have a significant impact on the terroir and fruit produced in the vineyards.

Famous quotes containing the word soil:
“The civilized nations—Greece, Rome, England—have been sustained by the primitive forests which anciently rotted where they stand. They survive as long as the soil is not exhausted. Alas for human culture! little is to be expected of a nation, when the vegetable mould is exhausted, and it is compelled to make manure of the bones of its fathers. There the poet sustains himself merely by his own superfluous fat, and the philosopher comes down on his marrow-bones.”
—Henry David Thoreau (1817–1862)
