This means we do not use herbicides or pesticides in the vineyards. We have invested in an under-vine weeder which helps to control weeds without the use of chemicals. We are also using compost and seaweed to improve the health of the soil and we will be encouraging beneficial insects by planting appropriate companion plants. Wild flowers have been sowed every seventh row.
All of our winery organic waste such as skins, stems and marc is returned to the vineyard. Pruning cuttings are mulched into the rows.
We do not use any chemical cleaners - only water is used to clean the winery.
Water Conservation
All grey water from the winery is processed in our dedicated waste water treatment plant and clarified water is used for irrigating the vineyard. This means that waste water goes back into the soil, rather than being pumped off site for treatment. As we do not use chemicals for cleaning, there is no risk of contamination of the unconfined aquifier which is located directly below the vineyard. Cooling water is reused in the winery.
Energy use
Stonecroft is a very energy efficient operation and the winery design is largely responsible for achieving this. High quality insulation means that heating is only required during the short period while the wines are undergoing malolactic fermentation, using a single small fan heater. Winter cooling is achieved through natural ventilation. Maximising the use of natural lighting reduces the need for electric lighting. Bottling and labelling is carried out by hand; labelling using a manual device which requires no electricity to run. We have no air-conditioning or central heating at the winery or in the cellar door.
Suppliers
Local suppliers are used where possible. As Stonecroft uses Diam corks rather than screwcaps, we are limited in our choice of bottles and so at present some of our bottles are imported. We hope to change this if local bottles become available.
