  • In other words, after all of the calculations of veraison dates and flowering dates, after all the analysis of photosynthetic rates, after all of that … the raw harvest dates are a better predictor of the Dijon temperatures than the Chuine calculated temperature … go figure.

  • With a standard deviation of 3.8 days, the 95% confidence interval of the delay between veraison and harvest is ±7.6 days.

  • This yields a 95% confidence interval on the veraison to harvest dates of about 3/4 of a degree.
