Burgundy - Côte d'Or, Côte Challoinnaise & Maconnais - The Growing environment and grape growing
4 important questions on Burgundy - Côte d'Or, Côte Challoinnaise & Maconnais - The Growing environment and grape growing
What is the climate in Burgundy
- Moderate continental
- from north (Dijon) to south (Macon) slightly warmer and dryer
- cold winters, warm but short summers
- CH and PN early ripening > suitable
- Morvan hills to the west provide protection from rainfall
- average rainfall 700 mm/y
- early autumn typically dry
Which factors influence the potential quality of individual sites in Burgundy?
- Aspect
- Elevation (degree of slope)
- Altitude (200-400m)
- Soils
What are threats in the climate of Burgundy
- Frost
- especially in spring > PN and CH are early budding> reduce of yields if occurs after budburst
- Hail
- in spring: reducing yields/total loss
- later in year: fruit damage, grey rot
- Rain
- early in year: disruption of flowering and fruit set, lowering yields, uneven ripening.
- during growing season: too much rainfall > fungal diseases
- at harvest > dilution and increase chance of rot
- Drought-stress
- irrigation not allowed
- berries shrivel/vines shut down
- slopes with more clay cope better with this
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What can be done agains problems with hail in Burgundy
- Limited use of anti-hail netting allowed since June 2018
- seeding clouds with silver iodide to cause rain/hail further away from the vineyards
- use of sorting tables
