Climate Change: in Vino Veritas
In truly fascinating new reasearch, scientists have searched historical records to collect data about when the grape harvest began each year. Their research wasnt published in the Journal of French Wine (I dont know if there even is one), it was published in the journal Climate of the Past. Thats because the date when the grape harvest begins is a clue to temperature.
