This paper analyzes the impact of annual weather fluctuations on the total output of wine and on the share of output of different wine-quality categories in Germany, using a set of wine data from all thirteen German wine regions and daily weather data taken from regional weather stations. The empirical analysis suggests that rising average temperatures have a significantly positive impact on the total output of wine as well as on the output shares of wine in higher- quality categories. The number of freezing days appears to be detrimental to overall produc- tion; precipitation during the growing season impairs higher-quality wines in particular.
