Suitability for cultivation and agronomic production
Sauvignon B is a very vigorous vine variety under certain conditions and has tendency to produce herbaceous characters. This vigor, which can be very intense the first years, thus needs to be managed by planting in moderately fertile terroirs and by using weak rootstock and also by using adapted pruning techniques. Along with careful trellising and adapted training systems, finding a favorable micro-climate for the grape clusters is necessary.
Sensitivity to diseases and pests
Sauvignon B is very susceptible to grey rot (compact clusters) and wood disease and sensitive to powdery mildew. It is however not very sensitive to downy mildew.
Technological potential
The grape clusters and berries are small in size. Sauvignon B can produce very elegant dry white wines: very fine, balanced and typical. Sauvignon B characteristic varietal aromas, which are especially present the first years, can encounter nuances (broom flower, blackcurrent, or boxwood) depending on the terroir, the year and growing conditions. After late harvests or with noble rot, this variety can be used to produce top liqueur wines.
