At Mitre's Edge Wine Estate we are wholeheartedly committed to green and ethical winemaking – it's a humble token of our appreciation of our beautiful earth that facilitates and supports our winemaking passion. Taking responsibility for our carbon footprint and ensuring that we contribute to reduced carbon emissions in our industry is an important objective at our estate.
Our farming operations are conducted according to best farming practices, and adhere to The Guidelines for the Integrated Production of Wine (IPW) as far as possible. The IPW system is one of the best, recognised internationally for its monitoring and statistical features from start to finish of the wine production process.
Our irrigation is managed scientifically using Aquacheck probes, which utilise an Aquawave GPRS unit that feeds into the Irricheck Irrigation system server every hour, providing irrigation recommendations every two hours. The resultant report allows us to produce for quality and ensures the efficient use of water.
All blocks except for the Shiraz were dry land farmed until 2013. We installed a new drip irrigation system towards the end of 2013, ready for the 2014 season. Our vines have however been planted on drought resistant rootstock, in preparation for any hot, dry summers.
We are a member of WIETA (Wine and Agricultural Ethical Trading Association) which is a multi-stakeholder, non-profit voluntary organisation which actively promotes ethical trade in the wine industry value chain through training, technical assessment and audits to assess members' compliance with its code of good practice. Stakeholders include producers, retailers, trade unions, non-governmental organisations and the government. In January 2014 we were audited by The Wine and Agricultural Ethical Trading Association (WIETA) and no non-conformances were identified.
We recycle all our household and winery waste, and we invested in a 25 KW grid-tied photo voltaic system installed by RenEnergy in July 2013. The first power from this system was generated on 18 August 2013.
This solar powered unit will pay for itself in approximately 6 years – based on Eskom’s current electricity tariffs – and has generated 72,500 kWh as at March 2015. It is operating at an efficiency of 8% more than the designers originally estimated, and therefore already represents a great return on investment.
