South African wine maker Neil Patterson Wines has unveiled a range of premium wines that uses photopurification to lower sulphite levels.

The range contains around ten parts per million of sulphites, compared to an average of 80 to 120ppm normally found in wines, the makers of the purification technology, SurePure Inc, said today (3 December). The company said the process replaces “traditional wine filtration systems”, resulting in “less harmful chemical intervention”.

The wines, including a 2013 Sauvignon Blanc, a 2012 Cabernet Sauvignon, and a 2009 Merlot, will be available in selected restaurants and wine shops in South Africa.

Neil Patterson, president of Neil Patterson Wines, said: "I believe there is significant market demand for a premium range that offers high quality sulphite free wines for discerning wine drinkers who are searching for the ideal unpreserved green alternative." 

Sulphites are produced naturally during the fermentation of wine.
