from the document:
And something I did a few years ago.
Note the vertical scales are offset but per division scales are correct
And a comparison to CET
There seems to be no further analysis (more recent than 2003) which was done by:
Chuine I, Yiou P, Viovy N, Seguin B, Daux V, Leroy Ladurie E (2004) Grape ripening as a past climate indicator.
From the above it seems that grapes despite possible cultivar changes give a good proxy for temperature.

The grapes seem to have hidden the decline of the LIA. It's a conspiracy of man and grape!
ReplyDeleteTake a look at Pfister aka Central European Temperature Record. Lots of stuff on grape harvests in nearby Switzerland

Eli Difficult finding your references. (perhaps paid access required?)
ReplyDeleteOne of the plots above does actually have swiss grapes included!
Any way thanks for the references
