Our aim is to product as much as we need and with the most wholesome product
to obtain the quality we wish.
The work cycle in the vineyard can be compared to the vegetative cycle of a plant.
Vegetative cycle : The main stages
Beginning of the viticultural
year: :the 11th of November, the Saint Martin’s
winter. This date of agreement was stated in the Middle
ages.
Bleeding of the vine:
:the rise of sap
at the beginning of Spring. Drops can be seen at the
end of each shoot.
Budburst: it all depends on the grape
variety, the weather and the soil. The blooming of buds
usually happens 20 or 35 days after the bleeding. This
is the budburst. We classify the grape variety according
to the budburst earliness.
Inflorescence :tiny grapes appear
concomitantly with the leaves
Blooming :the coming out of flowers.
The vineyard is then very weak to the late frost.
The berry set: flowers are fecundated
and become a grape-berry.
The change of colour of the grape-berry : this is the
ripening of the fruit. The grape-berries become bigger
and change their colour. They turn golden or yellow
(for the white grape), from garnet-red to dark-blue
(for the red grape). In the berry, tranformation occurs
and brings about a variation of the acidity rate (and
incidentally a transformation of tartaric acid into
malic acid) and an increase of sugar as well as the
density of mineral salt. This stage lasts about 50 days.
The grape gathering : the gathering
of grapes can be hand-made or machine-made. It can also
be postponed in order to wait for the raisining of the
grape or the arrival of botrytis that is going to concentrate
the grape sugar (for the sweet wines).
The permit harvesting : notice appointing
the date of the vintage, calculated according to the
date of the berry-set, 100 days after.

Work cycles in the vineyard:
The work of the vinegrower starts with the planting
of vine stock, but its main job relies on the training
of the vine which combines the density of plantation
with the type of pruning and with the grape variety.
Activities :
Ploughing, earthing-up and extraction
of the excesses of pebbles and stones (building of low
wall possibly).
Enrichment, providing with organic material
and mineral salt.
Planting of base of the wine. They will
only be fruit-bearing after 4 completed cycles and to
the fourth leave.
Pruning of the wine: first method used
to be able to check the yield and to improve the quality
of the grape produced by the selection of the number of
buds that are going to bear some grape. Indeed a too harsh
pruning is detrimental to the base of the vine and a too
weak pruning favours the surplus production.
Trellising (in chestnut tree, locust
tree or in galvanized metal).The low vine plants are not
trellised
Ploughing occurs in Spring to move and
aerate the land and weeding
Debudding: reduction in the number of
buds
Disease protection: mildiou, oidium,
phylloxera.
Spreading (choice of fruiting cane according
to their position on the vine and to their sun exposure).
Topping: pruning of the leaves vegetation
and of the extremity of the fruiting canes.
Green harvest: reduction of the number
of grapes by base of the vine achieved at summertime before
the ripeness.
The grappe gathering takes place after
the analysis of the acidity/sugar ratio and of potential
alcohol within the grape.
