Organic wines are produced using organic grapes and organic ingredients. They don't contain sulfites and genetically modified organisms (GMO). The process, too, is organic (doesn't use toxic or artificial chemicals). While a 100-percent organic wine is what considered as purely organic, there are also kinds of organic wine that are labeled "Organic" (95-percent) and "Wine Made with Organic Grapes" (70-percent).

1. What is Organic Wine?
Certified organic wine doesn't use any genetically modified organisms ("GMO's")
100% Organic Wine
Organically grown and Organic Wine
Wine made with Organic Grapes
GMO yeast for example, is allowed in conventional wines. And when it comes to other additives,
certified organic wines don't contain sulphites. However, wine labelled "Made with organically grown
grapes" may have sulphur dioxide.
Wine that is produced with grapes that are certified 100%.
Wine that has at least 95% of it's ingredients from certified organic sources. Organic wine
may have an additional 100 ppm of sulfur dioxide added to them.
Wines that has at least 70% of it's grapes from organic sources. These wines may have sulfur
dioxide added as well.
What's the fuss about
Organic Wine?
Grapes are one of the most chemically
"sprayed" (with insecticides, herbicides,
fungicides and other nasty "cides") categories
of produce on the market today. By switching
to organic wine, you can reduce your exposure
to insecticides, herbicides, and fungicides.
Does Organic Wine Taste of
Better than Conventional Wine?
Some people prefer the taste of organic wine
to the taste of conventional wine. French
organic wines show up consistently among
the top ten best wines of any region where
they are represented.
Organic Wine
and the Environment
Many organic vineyards hand pick their grapes,
rather than using mechanical pickers. Hand
picking of grapes allows only the ripest and
healthiest bunches to be picked, with the minimum
amount of stress/damage to the vine, fruit and soil.
Biodynamic farming techniques use a vineyard's
natural resources to cultivate grapes without
pesticides, fungicides, herbicides, synthetic
fertilizers or growth stimulants. A certified
biodynamic vineyard often meets or exceeds the
standards and regulations for organic-certified
farming.
Some wineries also take land stewardship and
living in harmony with wildlife seriously. They
educate workers, asking them not to kill native
snake species, which are often rare or
endangered. They might install snake barrier
fencing and incorporate worker safety training.
Others restore native habitats through planting
native shrubs, wildflowers and grasses or account
for losing some of their harvest to local wildlife like
bears.
