Peregrine Wines' managers and winegrowers focus on soil health to produce balanced and healthy vines that require the minimum of intervention and produce crops without the use of synthetic products.
Plants are living, breathing complex organisms. There are a myriad of organic systems that growers use, focusing on certain elements in the overall picture of producing healthy organic crops.
Peregrine believes that plants have natural ways of gaining nutrients from the soils they are growing in. Vines form a symbiotic relationship with Mycorrhizal fungi. The vine supplies carbohydrates to the fungi in return for nutrients that the fungi dissolves from the soil around them.
By not feeding vines at the surface with synthetic fertilisers, vines send their roots deeper looking for nutrients and water to sustain their needs.
The benefits of this include:
- Deeper rooting vines buffered from environmental extremes of drought and rainfall events
- The greater area populated by roots enables a greater influence on the flavour composition of the grapes
- No nasty chemicals to worry about – passing on this land to future generations in a better state is a key objective
- A healthy and rewarding result for people working in this environment
Other processes in organic viticulture focus around prevention rather than cure. Vines are pruned to allow an open canopy that prevents shading and reduces disease risk.
Summer management of vines also focuses on this open canopy structure. Shoot thinning, leaf plucking and fruit thinning are all management techniques helping to reduce the need for chemical treatment.
