Andi Mann is a renowned natural wine producer from the Rheinhessen region of Germany. He is dedicated to the holistic health of his vineyards and practices sustainable viticulture. His wines often exhibit a distinct minerality, showcasing the diverse soil types in his vineyards, which range from sand to limestone, particularly highlighted in his CALX range.

After studying economic sciences, Andi attended Geisenheim University, a prestigious institution for viticulture and oenology. He then took over his family estate, which dates back to 1699. Of the eleven hectares, five are devoted to natural wine production. The estate benefits from a variety of soils, including volcanic porphyry, and emphasizes biodiversity, "clean" viticulture, manual harvesting, and non-interventionist long vinifications. These practices result in wines of great authenticity and vibrant energy.

Andi Mann's estate is a significant contributor to the revival of German wines, especially those from the Rhine-Hesse region.
