Mediterranean climate and soil conditions at the foothills of the Langeberg Mountains in the Breede River Valley in the Western Cape of South Africa, and blending of the best cultivars, gentle hand harvesting at optimal ripeness and careful cold extraction within 24 hours after harvest, ensure the unique, fruity characteristics of Mardouw Olive Estate’s premium olive products.

Fertile land In 1795 the farmers of Swellendam declared themselves independent with Hermanus Steyn chosen to be the president of this new Republic, but his rein did not last long and Swellendam returned to its original status. On the Mardouw Estate you will find the grave of Hermanus Steyn.

Every journey begins with a single step. Mardouw Olive Estate took the first step in 2002, and now with many moments gone by our products are an ode to our history, a tribute to our heritage, a memento of our progress. The Verder family bought the 1000ha land from the Van Eeden brothers, and with the expertise of the Agricultural Department at the University of Stellenbosch, planted 50.000 trees to replace old vines, taking advantage of the much treasured water that comes down from the mountains to fill the Mardouw’s wells and dams.

“The advantage of having started less than a quarter of a century ago, is that we could benefit from the latest techniques in planting trees,” says André Verder, Mardouw owner. “High-density, with trees reaching no more than 2m, so that the branches and fruits receive the maximum exposure to sunlight, which in turn benefits not only taste but also oil content.”

Previously the land was made up of vineyards and various other fruits, but is now home to the most beautiful olive trees. The main house at Mardouw was built over 100 years ago and was tastefully transformed by the Verder family. One of South Africa’s Agricultural Research Council’s olive research specialists confirmed that the soil on Mardouw was excellent for growing olives. The soil together with the Mediterranean-like climate conditions made for perfect growing conditions for premium quality olives, especially Kalamata and Mission. The olive trees of Mardouw are planted using the latest technology in olive tree planting. The trees are planted to be no more than 2 meters in height, therefore providing easy entry for sunlight onto the blossoms and small olives on the branches ensuring excellent results.

Mardouw plants new trees of different cultivars annually. There are more than 50 000 trees on 43ha of land currently in full production. Mardouw Olive Estate is proud to produce excellent quality olive oil and table olives. The processing of our oil and table olives are done with the latest technology and our products are continuously checked by outside laboratories, ensuring only the best quality.

“All our olive products are produced with olives grown on our unique estate terroir – hence “Estate Oil”, irrigated with fresh mountain water, processed on the estate and free from colourants and preservatives,” says Chris van Niekerk, estate manager. “Mardouw’s extra virgin olive oil has a unique South African flavour with fynbos, pine needles, artichoke and fruit of green and ripe olives. A pleasant bitterness in the aftertaste is the signature of this well balanced medium extra virgin olive oil.”

Did you know that olive oil is only Extra Virgin when the acid content is below 0,8% and the peroxide value less than 20 mEq/kg?” Mardouw is proud to guarantee that we comfortably meet these standards.


The history of Mardouw dates back to the late 1700’s, but the land was bought by the Verder family in 2002. At the time, the land consisted of vineyards, and a variety of fruit trees. The Verder family decided that because of the fertility of the soil, something other than vines should be planted there. It was confirmed by one of South Africa’s top Agricultural Research Councils research specialists that the soil was excellent for the growing of olives. The soil, together with the Mediterranean-like climate, made conditions perfect for the growing of premium quality olives, especially the Kalamata, Mission, Frantoio and FS17 cultivar.

Mardouw Olive Estate is located at the foot of the Langeberg Mountains in the middle of the Garden Route, Western Cape, South Africa – about 200km from Cape Town.

Mardouw Olive Estate is proud to produce excellent quality olive oil and table olives. The processing of our oil and table olives is done with the latest technology and the products are continuously checked by outside laboratories, ensuring exceptionally high quality products.

Virgin olive oils are the oils obtained from the fruit of the olive tree (Olea europaea L. ) solely by mechanical or other physical means under conditions, particularly thermal conditions, that do not lead to alterations in the oil, and which have not undergone any treatment other than washing, decantation, centrifugation and filtration.

Olive oil is only Extra Virgin if the free fatty “oleic” acid content is below 0,8%. That’s the international standard, promulgated by the International Olive Council. Mardouw’s lab results return consistently remarkably low values: 0.24% FFA and 4.0 meq/kg PV for XXV, and 0.37% FFA and 6.0 meq/kg PV for EVOO

A new oil mill was added to our operation in 2015, and we started making our own Extra Virgin Olive Oil since that year. We have also just expanded our product line to include the following:
