The great accordance in the distribution of the annual temperature through
the different seasons, as presented by the results obtained for the valleys
of the Rhine and Maine, tends to confirm the accuracy of these
meteorological observations. The months of December, January, and February
are reckoned as winter months. When the different qualities of the wines
produced in Franconia, and in the countries around the Baltic, are compared
with the mean summer and autumn temperature of Wurzburg and Berlin, we are
almost surprised to find a difference of only about two degrees. The
difference in the spring is about four degrees. The influence of late May
frosts on the flowering season, and after a correspondingly cold winter, is
almost as important an element as the time of the subsequent ripening of the
grape.
