As climate change continues, it is set to get even dryer. By 2017, we aim to reduce our municipal water usage by 50% from our 2009 levels, through guest and employee awareness and the continuous monitoring and implementation of water-saving measures in every facet of our business. Wine farms such as Spier are dependent on sufficient and regular water supply, both in terms of supplementary irrigation of vineyards, and in the process of making wine. During the winemaking process in the cellar, Spier measures how much water it uses to create 1L of wine. From July 2013 to May 2014 we used an average of 2.14L of water to make 1L of wine. From July 2014 to May 2015 this consumption reduced to 1.96L of water used to make 1L of wine. According to the Integrated Production of Wines (IPW) environmental sustainability scheme, smaller South African win- As water scarcity increases, we take our commitment to conserving water seriously and believe in realising this commitment in an innovative and holistic way. On the land and in our winery eries like Spier typically use an average of 5.6 litres of water (cellar only – not taking into account irrigation, transport) for 1 litre of wine. Effective cleaning programmes, trained staff, water-saving devices, use of high-pressure machines and barrel steamers are all initiatives that reduce the use of water in our cellar. 98% of the vineyards on Spier farm are watered with drip irrigation. DFM irrigation probes are calibrated and provide data on how much water each vineyard and pasture needs, thereby allowing us to have an optimised irrigation strategy that ensures that only the necessary amount of water is irrigated.
