The autumn of 2009 was mild and wet whereas the first months of 2010 were particularly cold and dry. We then noted a delay in the budbreak which did not properly get going until April which was almost summery. Flowering was disrupted by rain and cool temperatures during the first half of June resulting in significant flower abortion and uneven grape size. We had to wait for the last ten days of June for temperatures to return to seasonal norms. Water stress began to develop at the end of June in some plots in the Enclos and increased in July. Generally, the vines stopped growing at the end of July.
