Crushing a grape sample to test the analytics
Two bite-sized snippets that afford plenty of perspective:
“With the potential harvest parameters of % veraison & vine health being heterogeneous from one plot to another it is, for the moment, very difficult to precisely project the optimal dates for the onset of the harvest. In terms of the stages of vine growth and summer rainfall (125mm in July-August in Beaune, which would be classed as ‘historically normal’), 2021 can be compared to 2012. These trends, to date, indicate starting points of 18-20 September but the evolution of the state of health in the first half of September (notably any development of botrytis) will come into play in the decision.”

“For the white grape varieties, due to excessive frost damage, only 2/3 of the data points will be available this year. Two-thirds of the sampled plots of chardonnay have passed the mid-veraison stage, however, maturity is not very advanced from an analytical perspective. The plots of aligoté, severely impacted by frost, cannot be sampled this year. For the black grape varieties, samples from a little more than 3/4 of the plots could be collected. These black grape varieties are the most advanced in maturity, particularly the pinot noir where most of the sampled plots are close to full veraison. The sugar contents vary from 145 to 150 g/l, except in the Yonne. The acidities are currently high, in particular, due to a significant presence of both tartaric and high levels of malic acids.”

There is one response to “another short update on the 2021 vintage”
Thanks Bill, for both this update and the previous one. Both very useful!
