An organic wine is a wine resulting from an agriculture and a wine making without chemical products of synthesis. The main labels AB and Bio Europe (which now have the same specifications) are the means to guarantee this approach. At the beginning, the European specifications regulating the “wine from organic viticulture” only took into account the field of viticulture and not the wine making.

This means that a wine whose grapes were organically grown, but for which synthetic chemicals were used during vinification, could very well receive certification. Since 2012, the new specifications renamed “organic wine” are more strict. The inputs (oenological products used in the winemaking process) are now taken into account in the attribution of the label. Even if a large number of products remain authorized…

Authorized Products for the Culture of the Vine :

Chemicals of natural origin can be used, but some synthetic products are exceptions. These include calcium hydroxide (or slaked lime), kerosene oil (from petroleum) and the famous “copper compounds” (copper hydroxide, copper oxychloride, cuprous oxide, Bordeaux mixture and tribasic copper sulfate).

The Amount of Sulfites Allowed

An organic red wine can contain up to 100 mg/l total SO2 (sulfites). While an organic white or rosé wine can contain up to 150 mg/l total SO2 (sulfites).

These are the list of oenological products that the winemaker is authorized to use during the vinification of an organic wine to guide the harvest.

Inspired by the theories developed by Rudolf Steiner, biodynamic agriculture is based on esoteric practices. Based on the principle that the soil is a living matter, it aspires to its balance and dynamism by taking into account the influence of the attraction of the planets and the moon. Indeed, for any operation in the vineyard or in the wine making, biodynamics relies on a specific calendar.

According to the positions of the stars and their forces of attraction influencing the living (e.g. the moon on the tide), certain days are more favourable to root operations (e.g. planting), to fruit (e.g. harvest), etc.

The two main labels guaranteeing a biodynamic practice are : Biodyvin and Demeter.

Authorized Products for the Culture of the Vine :

Basically, these are the same principles as organic agriculture, except that biodynamics goes further. Trying to improve the natural exchanges between the soil and the roots as well as the sky and the leaves, and in order to prevent or fight diseases, the winegrowers use natural potions based on infusions or macerations of plants sprayed in homeopathic doses. To energize the soil, they use cow dung that they bury in an ox horn, thus promoting the development of roots and microbial life.

Authorized Oenological Inputs :

These are the list of oenological products that the winemaker is authorized to use during the vinification of a biodynamic wine to guide the harvest.

Egg albumin (Ovalbumin) / Sulphur dioxide (SO²) / Bentonite / Charcoal / Sucrose (Sugar)

The Amount of Sulfites Allowed

A biodynamic red wine can contain up to 60 mg/l total SO2 (sulfites). While a white or rosé wine can contain up to 90 mg/l total SO2 (sulfites).

Authorized Products for the Culture of the Vine :

The vines must be managed in organic or biodynamic agriculture.

The Amount of Sulfites Allowed

Concerning sulphites, the definition of a natural wine is problematic… Some will tell you that a natural wine is without added sulfites, while others will say that a red, white or rosé wine called natural can contain up to 30 – 40 mg/l total SO2 (sulfites).

Authorized Oenological Inputs :

These are the list of oenological products that the winemaker is authorized to use during the vinification of a natural wine to guide the harvest. The list is short:

Sulphur dioxide (SO²)

Organic VS Biodynamic Wine

👉 Thanks to the explanations above, we can see that the main difference between an organic and biodynamic wine is that the specifications of the latter are stricter. In the vineyard, to have the biodynamic label, the winegrower sprays potions of plants, and to promote the microbial life of the soils, he uses cow dung buried in an ox horn. He must also respect the lunar calendar, which is not the case with the organic label.
Finally, during the vinification, the Demeter or Biodyvin label authorizes much less oenological inputs (including the famous exogenous yeasts that change the organoleptic profile of a wine), and a lower number of added sulfites. The winemaking is therefore much more natural.

Organic VS Natural Wine

👉 A natural wine is necessarily an organic wine, but the opposite is not true. In the vineyard, there is no difference. However, as we have seen previously, the organic label, during the vinification, authorizes more than 40 oenological inputs in order to correct or guide the wine (to acidify it, add wood chips, etc.). Whereas a natural wine only allows the addition of low doses of sulfites (30 mg/SO2 total). This makes a big difference… it’s not for nothing that we call it a “natural” wine… !

Biodynamic VS Natural Wine

👉 The difference between a natural wine and a biodynamic wine can sometimes seem blurred when one is not a connoisseur… Because a natural wine can be a biodynamic wine. But not necessarily… it can simply come from organically grown vines (in this case, it does not respect the Biodyvin or Demeter specifications). And the opposite is also true…
To put it simply, a biodynamic wine allows a few oenological inputs and a greater number of sulfites than a natural wine. While the latter allows only 30 mg/SO2 total sulfites (and no other inputs). Even though this may seem close, it makes a big difference in the mouth!

Conventional VS Natural Wine

👉 The difference between a conventional and a natural wine is quite huge… It’s almost not the same thing… A conventional wine is made from vines that are allowed to use synthetic chemicals, while those of a natural wine must be at least organic (and some biodynamic).
And the other big difference is in the winemaking process. It is allowed in a conventional wine to add almost a hundred products to correct and direct the wine (the list of products is available earlier in the article), as well as 200 mg/l total SO2 for white and rosé wines. Whereas a natural wine only allows 30 mg/l SO2 and no other inputs! We told you, it is not the same product…!
