CHARTER
OF COMMITMENT
For a wine to be able to carry the label
“Vin Méthode Nature”, farming and wine making must
respect and follow the 12 points mentioned below:

1 • Wines declared under the label “Vin Méthode Nature’’ must be made at least with
100% organically certified grapes (either AB,
Nature & Progrès or be in the third year of organic farming conversion). This applies for all
categories (AOP, IGP, Vin de France, etc.).
2 • Grapes must be hand-harvested.
3 • Fermentations must be spontaneous. The
inoculation of yeast or bacteria is not permitted.
4 • The use of oenological additives or processing aids is not permitted.
5 • No voluntary modification of the chemical
structure of the grapes is permitted.
6 • The use of brutal and traumatic physical
techniques (such as: reverse osmosis, filtration, tangential filtration, flash pasteurization,
thermovinification, centrifugation) is not permitted. The use of any other technique must be
notified to the Syndicate before being applied.
7 • The use of sulfites is not permitted before
or during fermentation, nor in any starter /
pied de cuvee. Sulfites can be added in the finished wine (whatever the color and the style) within the limit of a maximum of 30 mg / l H2SO4
total / l by Frantz Paul analysis (method of determination of free and total SO2 by distillation
/ oxidation). It is mandatory to inform the Syndicate and the consumer of any sulfite addition.
The use of added sulfites will be notified by a
dedicated logo (see 9.).
8 • During trade fairs, both winegrowers and
organizers are requested to present the “Vin Méthode Nature Charter of Commitment” alongside the bottles labeled “Vin Méthode Nature”.
Retailers are encouraged to do the same in their
business.
9 • Instructions on how to use “Vin Méthod Nature” identification logos:
• Can be used for wines without any
added sulphites.
• Can be used in the case of the presence of up to 20 mg/L of naturally
occurring sulfites. Analysis must be
made following the Frantz Paul methodology. No sulfite addition is allowed.
• Must be used if any sulfite is added,
whatever the quantity (even if below
< 10mg/L).
• Must be used as soon as more than
30 mg/L of sulphite is detected by
the Frantz Paul analysis.
10 • The “Vin Méthode Nature” label is awarded
each year and for each vintage after internal
control by the Syndicate and the reception of
the member’s declaration of honor.
11 • Within the range of wines produced by
a winery, the cuvées labelled as “Vin Méthode Nature” must be easily identifiable by
consumers. Labels must be clearly different
and indicate the logo and the methodology
“Vin Méthode Nature” next to the name of the
cuvée, in compliance with the legal labeling
regulation of the country.
12 • The winegrowers commit themselves
in their own name. All “Vin Méthode Nature”
vintages will be posted on our website www.
