From the importer:

Biodynamic. 100% Zweigelt, drawn from both vintage 2021 and 2022 (hence NV). Even though this red wine is inexpensive and cheerful in profile, it represents great value from the Nibiru cellar. The fruit for this bottling of the red ‘Oida’ comes from the Hiesberg and Steinleithen vineyards in Mollands. The vines in Hiesberg are 25-30 years old, with lots of rose quartz in the topsoil and primary rock beneath. This site has been farmed biodynamically (Demeter certified) since before Nibiru bought it in 2015. The vines in Steinleithen are about 65 years old. The topsoil is a bit more fertile here, and the base is decomposed primary rock dominated by mica schist. All the fruit is destemmed and crushed and stays on skins for the full primary fermentation. It’s aged in large format old barrels (500L-3000L) in Josef's grandfather's traditional tunnel cellar. Two years’ aging before bottling for all the various lots of fermentation; unfined and unfiltered. A joyful take on the table wine red blend, common in the Kamptal before Grüner and Riesling became all anyone cared about in the area.
