Plantagenet Wines have developed an understanding that life, like good wine, needs to be well rounded and balanced. With this in mind we’ve created a culture of caring for country and working towards sustainable practices throughout our production system.
Plantagenet Wines is very aware of how precious it is to reside where biodiversity is of international significance; with this awareness Plantagenet Wines has implemented a number of strategies for sustainability.
A selection of nitrogen fixing crops and native grasses are grown between the rows of vines to improve water retention, soil structure, soil biodiversity, fertility and reduce water run-off.
Fungicides and chemicals are only used on the estate when absolutely necessary. With the exception of clearing weeds for the establishment of new vines or creating legally required fire breaks, herbicides are not used in any of the vineyards. We also use sheep (hence the image above) through the winter months to graze the vineyard; eliminating the need for herbicide use and vineyard mowing during the wet period which are both harmful to soil health.
Our vine canopy management program improves ventilation and lessens the risk of fungal attack which in turn reduces chemical usage. Guinea fowl have been introduced into the vineyard as effective pest controllers.
The replanting of native vegetation in previously cleared areas that are not required for vines is an ongoing commitment to returning these areas to their original state. This brings welcomed biodiversity to the site which in turn assists with pest control.
In October 2007, Plantagenet was granted government funding for a Waterway Regeneration Project at the Rosetta property. The work was conducted under the auspices of the Great Southern Catchment Group and involved the clearing of weeds and pasture species from the land adjacent to the creek line. Fallen trees were then pushed into the creek to slow the water flow, create small ponds and raise the fallen water table to assist in the establishment of new native vegetation along the creek. This creek line was then fenced off. The project also included the planting of a range of locally native species.
A by-product of pressing grapes is the skins, seeds and stems; referred to as marc. For many years this by-product was sold to a local pig farmer. More recently it has been recognised as a rich organic product beneficial to the soil. It is now returned to the vineyard as mulch and in turn improves the water-holding capacity, health and biodiversity of the soil.
Winery buildings at Plantagenet Wines are constructed with maximum insulation to reduce refrigeration requirements.
