Wine without sulphite: characteristics and qualities
Sulphites, widely used in the modern oenology, are sulphurous dioxide added during the treatment of the wine to check the oxidation of the must, to keep the microbial level within the limits, to enhance the bright colour of the drink and to avoid alterations of the organoleptic properties, all with low costs.
It is popular the fact that a great quantity of sulphurous dioxide can be dangerous for the health of the human beings and for this reason, in the recent years, the wine makers were pushed to use biological production to make wine with low percentages of sulphites and, in some cases, without using sulphurous dioxide (SO2).
Wine without extra sulphites: some details
Quando si parla di vino senza solfiti si commette un’imprecisione.
When we talk about sulphites there is a common mistake: it is better if you say “extra sulphites” with reference to the additive introduced during production, leaving aside the one contained in the raw materials of the soil.
In fact, there isn’t a law, yet, for this type “free form”. What is certain is that the label has to say the truth and it has to be easily demonstrable and it has to be in compliance with the UE regulation 1169/2011 (in force from the grape harvest of 2012) at the cost of being subjected to civil, penal and administrative penalities.
To talk about wine without sulphites, it is necessary that this element should not be used in the different phases of the vineyard, neither in the other treatment that will be carried out in the winery.
Thus, to be certain of drinking a bottle of wine without sulphites, it is necessary to choose a green winery; it means that the winery should produce wine without using chemical substances and without the help of the technology, just taking advantage of the characteristics of the plants and of the soil.

This niche wines are addressed to the most demanding clients, that care of their own health. Generally, wines without sulphites have to have a concentration of these substances within 10 mg per litre.
