The project took nature-friendly vine cultivation on a family farm a step further to develop zero-waste processing methods that valorise all by-products of grapes in a sustainable and fully circular way. The resulting seeds, oil and flour have proved very popular with customers.

Project summary: 

The Kokol House of Wine grows 2.7 ha of vines in the Podravje region of Slovenia. The vines are managed using methods that reduce the negative impact of farming on the biodiversity and environment, and contribute to the mitigation of and adaptation to climate change. The environmental footprint of the farm has been further reduced by developing a closed loop that refines all wastes of wine production into new commercialised products. 
Grape seed oil is used as a food stuff and in cosmetics, while the flour generated by the cold pressing of grape seeds is used as both a nutritional supplement and as feed for livestock. Grape pomace without seeds is used as a fertiliser in vineyards.

Project results: 

2.7 ha of vineyards are cultivated totally free of herbicides and with minimal use of insecticides. The winemaking process produces 0% waste  thanks to circular practices and new product development. Approximately 1 000 kg of grape seeds are harvested and processed each year, a rise from 300 kg in 2017 and 500 kg in 2018. The grape seeds, grape seed oil and flour have been sold out each year and they currently account for approximately 10% of the business turnover. Through the marketing of grape seed products, the project has increased awareness of healthy eating and the use of cold-pressed oils, as well as helping to preserve the environment and jobs.
