Drought and cool temperatures contribute to optimal ripeness
The sum of summer temperatures in 2010 was close to that of summer 2009 (962°C compared to 982°C), but significantly colder than those of 2005, which totaled 1052°C. These cool temperatures had a substantial influence on the balance of our wines, preserving a good level of acidity and an attractive aromatic freshness.
Very little precipitation (only 267 mm) from March to August 2010 generating a drought of similar intensity to that of 2005, when only 227 mm of rain fell.
Another characteristic of the 2010 vintage is the low temperatures especially during the first three weeks of August, which allowed good acidity levels to be preserved in the grapes while maintaining an attractive aromatic freshness.
