Along with careful trellising and adapted training systems, finding a favorable micro-climate for the grape clusters is necessary.
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.
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.
