Bud burst period: medium.
Ripening period: medium-late.
Real fertility: 0,80.
Production: high, 40-50 t/Ha.
Detachment index: 1327g.
Cluster weight: 1100g.
Berry weight: 13 g.
Grape seeds: 3-4 per berry.
Sugar content: 13,4 (°Brix).
Total acidity: 4,2 (g/L).
Vegetation management: it is necessary to avoid an excessive thinning of the foliage, since the clusters are sensitive to heat.
Affinity with rootstocks: fair with 140Ruggeri, 110R and SO4. Obvious disaffinity with 1103Paulsen and Kober 5bb.
