The Prüm family has stewarded vineyards in the Middle Mosel since 1911, now managing 22 hectares across five celebrated sites. Graacher Himmelreich, one of their crown jewels, occupies less steeply sloped terrain than Wehlener Sonnenuhr, with deeper, mineral-rich soils that serve as water reservoirs during dry spells. The blue-grey Devonian slate gives way to pronounced minerality in the wines. Approximately 90% of the estate's vines remain ungrafted, slate's natural phylloxera resistance proving advantageous. The 2022 growing season brought early ripening driven by warm weather in May and summer heat; abundant September rainfall allowed shriveled berries to plump with juice, preserving aromatic freshness despite accelerated development.

Grapes harvested in early September 2022 underwent traditional Mosel processing. The estate employs entirely spontaneous fermentation without added yeast, allowing indigenous microflora to guide the transformation. Harvested fruit was gently pressed to separate juice from solids, with fermentation proceeding slowly in temperature-controlled stainless steel. The Spätlese designation indicates moderately high ripeness—Oechsle values yielding wines of delicate residual sweetness. Extended maturation occurred on fine lees, developing complexity whilst retaining the wine's characteristic freshness and mineral precision.
