RESUMO
French records of grape-harvest dates in Burgundy were used to reconstruct spring-summer temperatures from 1370 to 2003 using a process-based phenology model developed for the Pinot Noir grape. Our results reveal that temperatures as high as those reached in the 1990s have occurred several times in Burgundy since 1370. However, the summer of 2003 appears to have been extraordinary, with temperatures that were probably higher than in any other year since 1370.

Dog-days, cold periods, grape-harvests (France, 15-19th centuries). The climate history can be based on several kinds of data. In the present paper, French records of grape-harvest dates in Burgundy from 1370 to 1890 were used for evaluate the climates at these various period of time. These results reveal that temperatures as high as those reached in the 1990s have occurred several times in Burgundy since 1370. Correlations between temperatures and historic data are presented.
