Bronner is a variety with edges – and that’s exactly what makes it exciting. It grows between 400 and 500 meters a.s.l. on two contrasting sites:
→ Clay-rich, calcareous soil with dolomite content at the estate – a cool, elevated site
→ Lean, sandy gneiss-schist soil on a hot, terraced slope
Bronner shows clear traits in the vineyard:
→ Vigorous, upright growth in vertical shoot positioning – self-supporting with strong tendrils
→ Uneven budbreak, but evens out quickly
→ Early flowering, yet ripens late
→ Needs close attention in drought or with high yields – berry shrivel is a known issue
→ Typically 2–3 clusters per bud; wood ripening is stable
