> which as I pointed out is actually a more useful comparison point for harvest date since AFAIK there's been less change in the grapes grown or style of wine produced.
Sorry for the late reply, but you should check out the underlying paper if you haven't yet: https://www.frontiersin.org/articles/10.3389/fpls.2016.00069.... Their result crucially depends on assuming a 7 day adjustment in harvest date in the early years to compensate for the change in style of wine produced. Possibly necessary, but I think it greatly undermines the strength of their conclusions.
Have you written anywhere else about your grape growing experience? I've been trying to learn more about the recent short season northern grapes that have been coming out recently.
