TEMPERATURE– Degree or Intensity of Heat Present In a Substance or On a Particular Object, Expressed/ Shown by Thermometer

“You Can Grow Grapes Almost Everywhere On Earth, but There’s a Difference Between Growing Grapes In Sweden and Making a Commercially Viable Wine With the Grapes.”

  • VITICULTUREBENEFITS– The Most Important Aspect to Growing Grapes In Ample Sun and the Ability to Ripen the Grapes.
  • VITICULTURECHALLENGE– –High Temperature– Effect On Acidity and Ripening, Viticulturist Must Match Varieties to Temperature, Regions. Grapes Don’t Like Hot Temperatures During Harvest, This Upsets Sugar and Acid Balance. Grapes Will Not Ripen In Regions with Annual Temperature Average Under 50*. Low Temperature at Altitude Can Negatively Effect Bud Break and Ripening.
  • VITICULTURECHALLENGE–  ~Freezing Temperature~
  • **Refer to VITICULTURE CHALLENGE/ Freezing For Detailed Information

DIURNAL SHIFT= Degrees of Temperature Fluctuation Between Day-Time High and Night-Time Low (90* Day Time Temperature,  55* Night Time Temperature is Diurnal Shift of 35*)

  • Diurnal Shift Scale–  Large +50*   |   Medi 40*   |   Short -30*
  • Diurnal Shifts Can Be Quantified In Day or Year
  • During Day Grapes Expand In Size, and at Night Grapes Cool and Reduce In Size. This Natural Phenomena Allows Ripening Grapes to Balance Sugars With Acidity. The Acidity Gives Wines a Liveliness In Their Youth and Also the Ability to Achieve Longevity Though Aging.
  • Malic Acid Slowly Dissipate In Constant Warm Temperature, Cool Nights Help Preserves Acid.

INVERSION LAYER= Deviation From the Normal Change of Atmospheric Property With Altitude, Increase In Temperature With Height. Inversion Layers Tend to Prevent the Air Below From Rising Above

  • Every +Alt.100mt./ 330ft. Reduces Temperature 1.08*

TEMPERATURE INVERSION= Thin Layer of Atmosphere Where the Normal Decrease In Temperature With Height Switches to Temperature Increasing With Height. An Inversion Acts Like a Lid, Keeping Normal Atmosphere From Penetrating Through the Inversion.
