Terra Est Vita – Soil is Life
To make extraordinary wines you need an extraordinary rich web of life in the soil. At Avondale we are acutely aware that healthy balance in our vineyard eco-system, in our wines and in our own lives is dependent on first achieving healthy balance in our soil.
Avondale has 13 different soil types on our land – from cool, dark loam to decomposed granite and decomposed sandstone; from no rock to 75% rock.
According to soil type, we planted our vines in particular soil pockets in blocks of around one-hectare.
When we built our cellar we made sure that fruits of each block could be vinified separately to gives us optimal blending opportunities.
Restoring balance and fertility to Soil:
We use the soil balancing system pioneered by environmental scientist Dr William Albrecht, a respected authority on the relationship between soil fertility and ecosystem health.
Through re-mineralisation we have returned vital, natural mineral elements to our soil which is enhanced by the pure quality of the spring water we use for irrigation.
This re-mineralisation process works in conjunction with maintaining a diverse plant community that provides food and shelter for an abundance of soil microbes.
Avondale makes use of up to 10 different mixes of cover crops, which includes the sowing of the seeds of indigenous plants, to create a vibrant, diverse plant community right in our vineyards.
Biodiversity throughout the system
The measure of the robustness of any ecosystem can be found in its biodiversity. Multitudes of life forms reduce vulnerability, protect the ecosystem from shocks and enable it to restore and regenerate more quickly.
Avondale was one of the first South African wine producers to be awarded the Biodiversity in Wine certification.
While we do have an ongoing restoration project to clear alien vegetation on the farm and plant hundreds of indigenous trees, we do not confine our efforts to promote biodiversity to just the marginal uncultivated areas of our land.
We strive for biodiversity throughout the farm, and particularly in our actual vineyards.
Our intricate cover cropping system throughout the seasons, which includes the nurturing of indigenous fynbos plants, fosters micro-life in the soils and attracts an abundance of beneficial insects.
The land also supports a variety of naturally occurring birds, frogs, reptiles, small and larger mammals. The Cape Foxes which breed on the farm, the shy foraging of Common Duiker, Grysbok and Steenbok, the night-time wanderings of Red Caracal, Porcupine and Spotted Genets, and the pair of Black Eagles that soar down from the mountain cliffs to hunt Rock Hyrax are all testimony to the health of our environment.
