Mullineux proudly follows an environmental, social and governance (ESG) strategy, a long-term business model that emphasizes social and environmental responsibility. This is achieved by creating sustainable and ethical farming practices by focussing on a natural, minimalist approach followed both in the vineyards and the cellar.

To protect and preserve the land, no weed killers, insecticides, or any systemic fungicides are used. A variety of cover crops are planted in the winter to prevent erosion, build organic matter in the soil, provide shade for the soil and to prevent weeds from growing among the vines. Further to this, an extensive use of mulch and composts are applied, which are made from indigenous organic matter on the farm, including that from the free ranging Nguni cattle on the property.

Only the best wines that are a true expression of the Swartland are bottled and each stage of the winemaking is carefully considered, paying the highest possible attention to detail during every step.

The winemaking style of freshness, balance, elegance and purity of Swartland terroir is achieved by using indigenous yeasts, little new wood and low intervention in the cellar. Apart from minimal amounts of sulphur, nothing is added to, or removed from the wines and there is no use of any yeasts, acids, tannins, enzymes, or fining and filtering agents.
