Figure 2.3 Climate-maturity groupings based on growing season average temperatures. The
horizontal bars represent the range of temperatures for which each variety is known to ripen
and produce high to premium quality wine in the world's benchmark regions. The dashed
line at the end of the bars indicates that some adjustments may occur as more data become
available, but changes of more than +/− 0.2°-0.5°C are highly unlikely (Jones et al., 2012).
