Lucy Margaux, founded by Anton van Klopper in the Adelaide Hills, Australia, stands at the forefront of the natural wine movement. Van Klopper, originally hailing from South Africa, embarked on a winemaking journey that challenges conventional norms, embracing a minimal intervention philosophy.

His approach is characterized by the absence of added yeasts, filtering, and fining, making his wines a pure expression of the grape and its terroir. The winery's commitment to no sulfur addition at any stage of the winemaking process marks a significant move towards entirely sulfur-free wine production.

Van Klopper's creative spirit is also reflected in the wine labels he designs, underscoring his work's spontaneous and dynamic nature. The winery, situated on a farm previously known as a cherry orchard, now produces an array of unique wines, all from organically farmed fruit.

The South Adelaide wine region in South Australia is known for its diverse climate and varied terroir. This region includes the famous McLaren Vale and Adelaide Hills, each with distinct characteristics. McLaren Vale, situated near the Gulf St Vincent, benefits from a Mediterranean climate. It has warm, dry summers and mild, wet winters. This climate, combined with ancient soils, is ideal for viticulture.

Adelaide Hills, located at higher elevations, experiences a cooler climate. This region has significant diurnal temperature variation, which helps preserve the grapes' acidity. The soils here are diverse, ranging from sandy loam to clay, contributing to the complexity of the wines.

Grape varieties in South Adelaide are varied. McLaren Vale is renowned for its Shiraz, which produces rich, full-bodied wines with dark fruit flavors and spice notes. Grenache and Cabernet Sauvignon are also significant, along with lesser-planted varieties like Mourvèdre and Tempranillo. Adelaide Hills is known for its cool-climate varieties. Chardonnay, Sauvignon Blanc, and Pinot Noir are prominent, producing wines with bright acidity and elegant structure.

The wine production techniques in South Adelaide emphasize both tradition and innovation. Many producers focus on sustainable viticulture and minimal intervention in the winery, which aims to reflect the natural characteristics of the terroir in the wines.
