The grapes for the grand vin are principally from the Begadan vineyards.
Chateau La Tour de By 2015 is a blend of Cabernet Sauvignon (60%), Merlot (35%) et Petit Verdot (5%) aged for 12 months in French oak barrels.
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 decidedly chillier than those of 2005, which totalled 1052°C. These cool temperatures had a substantial influence on the balance of our wines, preserving a good level of acidity and attractive aromatic freshness.
Very little rainfall (only 267 mm) from March to August 2010 generating a drought of similar intensity to that of 2005, when only 227mm of rain fell.
Another feature of the 2010 vintage is the low temperatures above all in the first three weeks of August, which made for the preservation of good levels of acidity in the grapes while also maintaining attractive aromatic freshness.
