What is artisanal wine, and therefore what is meant by organic wine, natural wine and biodynamic wine?

You have to imagine artisanal wine as a whole that contains within it three subsets that represent three ways of approaching the vineyard and winemaking, respecting the environment, the operators and the end customer.

The amount of wine produced affects the categorization, especially in relation to the hectares available to the company, but normally is defined as artisan a company that produces less than 50,000 bottles per year.

Let's look specifically at these three subsets:

Organic Wine

Wine biological has the certification, you recognize it immediately, a green logo with stars representing the states of the European Union, and is obtained within it with products to 95% organic.

It is controlled from agricultural production to marketing, according to EU regulations, in the case of Italy, by the Ministry of Agriculture, Food and Forestry (MIPAAF).

The 60% of producers who produce organically do not in fact have certification, due to the cost and bureaucratic time of conversion, three years.

The minimum requirement is not to use chemical products in the vineyard and to contain a total sulphur dioxide level of 150 mg/litre for white wines and 100 mg/litre for red wines.

Even if it is not the practice, it is possible to produce organic wine using yeasts selected in the laboratory (I will explain shortly how they differ from the autochthonous yeasts), maintaining a controlled fermentation temperature and adding sulphites, which have an antiseptic and antioxidant function.

Biodynamic Wines

Biodynamic wine is produced in symbiosis with nature, with the phases of the moon and according to Rudolf Steiner's precepts concerning the restoration of the correct connections between heaven and earth. Certifications are still being defined at European level (Demeter International).

In biodynamics It is believed that the Moon in perigee (maximum proximity to the Earth) has a negative and hardening effect, contrary to what happens when it is in apogee.

In the vineyard, chemistry is eliminated and the use of tractors is limited, while the practice of green manure is encouraged (the introduction of leguminous plants into the vineyard which regulate the nitrogen levels in the soil).

Preparations are also used that trigger the processes of hummus formation, such as Preparation 500, the notorious Cornoletame, or that stimulate the functions of light and heat, as in the case of Preparation 501, Cornosilica. This is obtained from a mixture of quartz, feldspar and orthoclase, crushed, mixed with water and placed in a cow horn.

It is dispensed in very small quantities and has the function of processing the qualitative and organoleptic aspects of the product.

A peculiarity of biodynamic viticulture is that it creates a symbiotic system within the vineyard, often surrounded by walls similar to the French clos, whereby diseases are fought by the organisms themselves that populate the parcel of land.

Biodynamic wine is a pure expression of its land and its minerality, they are unique products, often very different from one vintage to another. They are wines totally aimed at environmental sustainability.

The trend in the winery is to abandon selected yeasts and controlled temperatures, in search of an increasingly real wine.

Natural Wines

The natural wine is obtained without any adulteration of the production process that includes the vineyard, the grape harvest and the cellar.

Mind you, these wines actually require very little human manipulation (harvesting, winemaking) so to define this category as natural is probably improper. I prefer to define them as respectful, genuine, true, sustainable and minimally manipulated. Without chemistry or laboratory yeasts.

Okay, maybe natural wines sounds better.

In the vineyard, only the use of copper sulphate is allowed, in very low quantities, as a pesticide and fungicide. In recent years many natural companies are experimenting with alternative treatments, even imaginative but not without logic or effectiveness, such as the use of lactic acid bacteria, orange juice or tannin from wood.

As mentioned, vines can only receive water when it rains, for the reasons explained just above, with a few exceptions related to a rather torrid, one-off climate.

Harvesting is always manual, without using tractors in the vineyard, the vinification is clean, without adding sulphites and using selected yeasts.

In the skin of the grape, in fact, there are naturally found the sulfites that the wine needs. Here the total sulphur dioxide is almost always under 50 mg/litre, in many cases it is around 20 mg/litre.

Organic red wines contain 100 mg/litre and white wines 150 mg/litre, a huge difference.
