Sulfites free wines: about the Italian ones.
Even in the most natural of vinification, the same yeasts produce sulfites during alcoholic fermentation.
Therefore, even if in limited quantity, there are actually sulfites in wine.
B) When and why the Italian label displays the words "wine without sulfites"
If the content of sulphites in wine in question is included in the maximum limit of 10 ml per liter, the wine can be qualified as "sulfite-free wine."
It should be noted that, in Italy, while at the overrun of that limit it is mandatory to write the words "contains sulfites", if that limit is not exceeded, the winery is free to write or not to write on the label "wine without sulfites" or " no added sulfites "wine.
To give a practical example, on sunnyfinch.com you will find two "natural wines" from the same winery, which indicate on the label the words "contains sulfites" although sulfites in wines are less than 10 ml / liter.
C) Natural wines and sulfites
In order to drink wine without sulfites shall we buy "natural wines"?
No. Or not necessarily.
It's true that the production philosophy of natural winemakers is based on the no use of oenological practices and the non-use of additives, including sulfur.
But in Italy there are no specific laws regulating the "natural winemaking" and no formal control is conducted in this regard.
For all we know, even if it is not a standard, the same producers of natural wines regard sulfur contents included in 30 ml / liter as tolerable quantities.
In conclusion, we could face the choice between natural wines of Italy labelled with the warning words "contains sulphites" and organic or even conventional wines that highlight the description "wine without sulfites."
