Madeira vine training system
latadas, now VSP (airflow and mechanisation)
VDN vine training system
bush vines, VSP, low density depending on site.
Shady canopy avoids sunburn & excess shrivelling
Sherry soil(s) and description
albariza- limestone (chalk), silica, clay
Barros- clay
arenas- sand
What soil does moscatel grow on
Arenas
What is the difference between limestone and chalk
chalk is a sub type of limestone with a high calcium carbonate content
Impact of albariza
- crust prevents evaportation
- water retention increases planting density
- aids in ripening due to reflection from white soils
How does albariza work (structure)
shell remenants from acquatic microorganisms created a porous structure which acts like a sponge in the raining season. Water is slowly released during the growing season
Madeira soil(s) and description
variable soils due to volcanic activity
Banyuls vineyards soils and description
steeply terraced schist slopes
Maury soil(s), description, and location
dark schist stores heat during the day and releases it at night aiding in ripening.

Disease and climate pressure in Southern France
sunburn, excessive shrivel,
Disease and climate pressure in Port
drought, heat stress, fungal disease, errosion
Disease and climate pressure in Madeira
high disease pressure due to humidity. both mildews, grey rot, and phomopsis.
Which side of Madeira is drier? why?
The south. Moist air from the north cools and condenses as it travels up the mountain making this part wetter and cooler.
