The
Bordeaux vineyard extend on 116,000 hectares, out of which
113,000 in A.O.C (guaranteed vintage). More than 80% is planted
in red vine-plant as white shrank considerably during the last
five decades. 11,000 owners produce about 6.3 million
hectolitres, representing close to 2.5% of the world production
of wine.
Geological formations dating back several million years were in
large part eroded then partially recovered by siliceous and gravely
siliceous alluviums transported and deposited by rivers coming
down from the Pyrenees and the Massif Central. But it is mainly
during the Quaternary that the largest part of the gravely siliceous
alluviums deposited in the Bordeaux area: alluvial layers of the
Isles (Lalande de Pomerol, Pomerol, north-west of Saint Emilion),
of the Dordogne (south of Saint Emilion and Graves de Vayres)
and the alluviums of the left bank of the Garonne and Gironde
which constitute the laying of Sauternes, Graves and Haut-Medoc.

The
region of Graves de Vayres, Appellation
d’Origine Contrôlée (AOC or Guaranteed Vintage
Area) covers a sheer 700 hectares on part of the only commons
of Vayres and Arveyres. Situated on the left bank of
the Dordogne, fronting Fronsac and Saint Emilion, it
forms a small inclusion of gravel in the vast area of Entre-Deux-Mers
which has a soil of a very different nature.
The soils on which are produced the wine of Graves de Vayres
are made of sand-gravel and sand-clay on a gravely under layer.
They come from the Pyrenees layer which emerges at the Dordogne
left bank. Along the river the area benefits from the moderating
effect of the water mass and a particular micro climate due
to the stiff relief of the opposite bank.
With this specific terroir the wines of Graves de Vayres were
perfectly identified at the beginning of the 19th century. The
Guaranteed Vintage of Graves de Vayres was officially recognised
in 1931 by a decree of the Appeal Court of Bordeaux,
and designated as an AOC by the INAO (Guaranteed Vintage National
Institution) in 1937.
The Graves de Vayres AOC comprises forty odd chateaux. Its red
wines with a magnificent ruby colour are smooth and delicate.
Drunk young, thanks to the merlot they are fresh and fruity.
They age very nicely and reach a splendid balance and smooth
strength.

Le
Vineyard
>>
It
extends on 14 hectares on the Vayres plateau, planted 80% with
merlot and 20% cabernet sauvignon, on a gravely soil.
The vines, 20 years old in average, are thoroughly taken care
of and their yield is kept under strict control in order to
extract the best possible quality from the terroir. Sugar and
flavour concentration as well as harvest quality are better
in a vine with lower yield. This is due to the simple fact that
the sap of the vine stock feeds less bunches, and also less
clusters are better exposed to the sun.
The vine must also “suffer” and fight for humidity
in depth. This is why some plots of land were heavily drained
as shown on this picture taken in 2002.

The Vine nursing starts in winter with a short pruning in simple
or double guyot. Next comes the removal of excess branches to
suppress the non fruit bearing young shots. This allows a better
airing of the bunches, and once more, vine nutriment concentration.
The leaf stripping in summer improves the display of the bunches
to the sun, thus allowing a better ripening process and
grapes’ health.
The green harvest, or thinning out of the bunches, consists in
suppressing a certain number of bunches in order to limit the
yield still more. In addition to the aforementioned concentration,
this produces a more homogeneous maturity.
Finally the harvest, entirely made by hand at Chateau
du Petit Puch, allows a first sorting of the bunches
on the vine. Collected bunches are gathered in small boxes of
about ten kilos capacity, in order to avoid piling up and crushing.
It is a fact that oxidation and consequently the loss of organoleptic
quality of the grape starts as soon as it skin is broken. Therefore
this should not happen prematurely.
