The 50 hectares of Léoville and 17 hectares of Langoa, planted in gravelly soil with a clay sub-soil, include large proportions of old vines in order to obtain the best possible quality. The grape varieties is 74% Cabernet Sauvignon, 23% Merlot and 3% Cabernet Franc for Léoville Barton, while Langoa Barton’s terroir is shared as follows 57% Cabernet Sauvignon, 34% Merlot and 9% Cabernet Franc. Both properties have the same vinification methods.
The wines are typical of the Saint-Julien area, well balanced wines with subtle bouquets and flavours; the emphasis being on elegance and finesse rather than on power and extraction. This is achieved by picking the grapes at their maximum ripeness and allowing the fermentation to take place at a controlled temperature of 30/32°C. Although excessive extraction is avoided by removing the juice from the skins at the appropriate time, the wines have a lovely deep colour, excellent structure and sufficient tannins to ensure good ageing potential.
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.
