Curious about orange wines? Try this Sauvignon Blanc from Maria & Sepp Muster. Forgettable Sancerre this ain’t. Based in southern Austria, not far from the Slovenian border, the Musters tend10 hectares of vines and are certified biodynamic by the very strict Demeter Austria. The steeply sloped vineyards are formed of rocky, clay and silt soils with some limestone, and they’re at an altitude of around 450 metres. Southern Styria has warm summers with cool nights, and cold winters. The vines are trellised on chestnut posts with a single wire at 1.8 metres. Canes are trained along this and then the foliage hangs down, giving the vineyards a slightly wild look. But it works in this climate – it’s the traditional method here. Winemaking is quite natural. All ferments are spontaneous and the wines mature for long periods in barrel – normally at least two years. They are then bottled without fining or filtration, and some wines are made without added sulfur dioxide, while others have small additions.
