Markus Altenburger works in Leithaberg, one of the key regions for Blaufränkisch in Austria. He farms organically, keeps the winemaking simple (native fermentations, minimal oak, low intervention), and focuses on showcasing the soil — especially limestone (“Kalk”). His wines are known for being precise, clean, and very drinkable, without the rustic edges Blaufränkisch sometimes has. “Vom Kalk” is his straight, no-nonsense expression: pure fruit, mineral backbone, and a refreshing style you can open any night.
