Macadamia Production

Macadamia Production

Botanical name: Macadamia integrifolia

Summerfields Farm comprises 100 acres of rolling hills running down to the river, with orchards of macadamia and litchi trees and granadilla plantations.  Summerfields Rose Retreat and Spa take up only a small portion of the farm.

You may be familiar with macadamia nuts, which are one of the most popular varieties of nuts, due to their rich flavor and high nutrient profile. However, what’s even more valuable is the macadamia nut oil that can be extracted from these nuts for a number of uses. The fatty acid composition of macadamia nut oil makes it extremely valuable as a vegetable oil for frying or cooking. Although many people consider “fats” to be bad across the board, the truth of the matter is that we need certain mono-unsaturated fats to balance our cholesterol levels and ensure that our bodies run smoothly.

Summerfields Rose Retreat and Spa have become well-known for the macadamia products we use in the restaurants and spa.

The owners of Summerfields Estate, Andre and Ilse, and their children Natia, owner of the River Café, and Antoine, owner of ButtaNutt, have a vision to create an environment where active farming and warm hospitality can co-exist in a wonderfully unique way.

We export the macadamia nuts to Europe, and use this produce in our food, in value-added products such as chocolates, sorbets and ice-creams, cakes and puddings. Our products are for sale on the property

Besides being a food source, the husks are composted for mulch or for fertilizer, the oil is used in the cosmetic industry to make soaps, shampoos, and sunscreens. One of the other antioxidants in macadamia nut oil, squalene, is somewhat rare and has a particularly strong impact on our skin. Squalene is a naturally occurring antioxidant in our body, but adding more through macadamia nut oil can help reduce oxidative stress on the body’s fats and the skin, helping to prevent wrinkles, age spots, slow healing rates, and other signs of aging. It can be used on its own as a moisturizer for the skin and hair. This is why macadamia oil is used in our Rose Spa.
Macadamias are a tough nut to crack, as the saying goes. Containing at least 72 percent oil, they’re encased in a leathery, green husk that splits open as the nut matures. Harvest comes when they fall from the tree, which is when the husk is removed and the nuts are dried. The shell can then be removed using a nutcracker. A handful of these nuts makes a crunchy snack.

The Summerfields Kitchen had become known for the macadamia butter and oils we produce from our freshly organic grown macadamia’s.
