The 2022 growing season gifted Wehlener Sonnenuhr with ideal conditions for Spätlese-level ripeness. Early May warmth accelerated bud break and development, with sustained summer heat concentrating fruit flavours across the slate slopes. The vineyard's 70%-gradient terrain maximised solar exposure even as vines matured ahead of schedule. The Prüm family's decision to harvest selectively in mid-September—later than lighter-level fruit but before the month's abundant rainfall—captured the sweet spot between concentration and freshness. Approximately 90% of the estate's vines remain ungrafted in the slate; these elderly vines produce smaller berries with lower yields but heightened concentration, ideal for Spätlese expression. The 2022 vintage's dry summer had firmed berry skins, minimising disease whilst the September rains plumped the fruit with essential hydration.

Spätlese fruit, harvested in mid-September 2022 at moderately elevated ripeness, underwent pressing to gentle pressure-only standards, preserving juice clarity. The estate's foundational technique—spontaneous fermentation without added yeast—allowed indigenous microflora to guide fermentation in stainless steel vessels. The vintage's early ripeness meant fermentation proceeded relatively briskly, yet the Prüm family resists temperature control, preferring natural fermentation rhythms. Extended maturation on fine lees through autumn and winter developed the wine's characteristic minerality and complexity. Spätlese designates berries gathered at higher ripeness than Kabinett but lower than Auslese, resulting in wines with moderate residual sweetness and pronounced acidity—ideal for food pairing.
