Just from a temperature perspective, we can look at the temperature range this year recorded by our vineyard weather station. Given a high of 106 degrees, and low of -11, that’s… a range of 117 degrees. Add in the heat index and wind chill and the total degree range for the year was probably closer to 140 degrees. That’s a HUGE range. How much do you let your thermostat vary throughout the year? Certainly not that much. Those are tough grapevines!
