Which rootstocks are best suited to Burgundy vineyards for the next 50 years? In a recently published guide, this was the question the marketing board attempted to provide answers to.

From climate change and environmental transition to vine die-back, winegrowers everywhere are going to have to adapt (....). One of the solutions for adapting is plant material”, say experts in the guide’s preamble. “This report is designed for technicians and winegrowers in Burgundy, who will find in it avenues for thought and maybe even ideas for experimentation”.

After some background information on plant material, including the very low take-up of rootstock diversity (41B, SO4, 3309C, 161-49C, and Fercal), winegrowers will find a description of 20 rootstocks of interest in a changing climate. Examples include 140 Ru, 333 EM, and Rupestris du Lot.

According to the BIVB, Rupestris du Lot is “often found during surveys of mature southern vineyards. It therefore offers good drought-resistance, particularly in light of climate change. However, the rootstock also yields significant vigour and must therefore be used in poor, low compaction soils with little limestone content. It cannot be used widely across Burgundy but can be adapted to certain situations. Blending with Pinot seems to work well from an agronomic perspective”.
