HUMIDITY

HUMIDITY– Amount of Water Vapor In Atmosphere at Any Given Time, Measured as Percentage of Relative Humidity (%RH.)

• VITICULTURE– BENEFIT–
  • Perfect for Botrytis

• VITICULTURE– CHALLENGE–  ~High Humidity~
  • Wet and Humid Weather is Associated With Disease Pressure Like Mold/ Mildew/ Fungal Diseases and Has Effects On Vine Growth and Development as Well as Storage of Wine In Barrels.
  • Perfect Conditions For Botrytis

• CLASSIC HUMID CLIMATES
  • Rheingau Tokaj Aszu DHC.
  • Heusiedlesee-Hugelland
  • Contnari Alsace AOC.
  • Sauternes AOC.
  • Brazil

DEW= Water Which Condenses On Vines When Air is Cool Below “Dew Point”

• Dew Point- Point When Air Becomes Fully Saturated by its Water Content

EVAPORATION= Conversion of Water From Liquid to Gas or Vapor Brought About by Absorption of Heat.

• From Soil (Reduces Water Available to Vine and Causes Water Stress)
• From Grapes Vine Leaves (Transpiration)
• From Grape Bunches
• From Storage (Causes Loss of Wine Stored in Oak Barrel During Maturation)

TRANSPIRATION= Process of Water Movement Through a Plant From the Roots to “Aerial” Parts, Such as Leaves, Stems, Flowers Where it Changes to Vapor and is Released to the Atmosphere.
