Climate and Wine Quality: Temperature variability

Whereas potential wine style depends broadly on average mean temperature during ripening, quality appears to be related at least as much to short-term temperature variability from day to day. It has yet to be established whether less variable (or more equable) ripening temperatures are likely to result in better wine quality but highly variable temperatures risk greater damage, both by frosts after budburst and by extremes of heat in summer.
