Suitability for cultivation and agronomic production
Mauzac B displays moderate vigor is rather productive and must be short-pruned. Grape clusters have short stalks. This vine variety produces good results in clay limestone or limestone soils.
Sensitivity to diseases and pests
Mauzac B is sensitive to mites (particulary to acariosis),grape caterpillars, excoriosis, eutypiosis and grey rot. It is however not very susceptible to powdery and downy mildew.
Technological potential
Grape clusters and berries are moderate size. Mauzac B produces dry, sweet or sparkling white wine. At full maturity, the alcohol level is fairly high and the berries can continue to become enriched when overripe. Acidity, on the other hand, drops quickly. The wine sometimes lacks freshness (sensitivity to oxidation) and can sometimes display bitterness. The dominant aromas, in general, are apple and sometimes pear.
Clonal selection in France
The 7 approved Mauzac B clones carry the numbers 575, 738, 739, 740, 741, 898 and 899. A conservatory of close to 200 clones was set up in the Gailllac vineyard region (Tarn) in 1998.
