Wine without sulphite (added)
It is a " no sulfur added " wine. During its elaboration, from the vineyard to the bottling, the wine has not had any sulphur (sulphite) added. The natural development of the yeasts is nevertheless accompanied by the formation of sulphur compounds that will be found in the wine, of course in very low dosages.
It is therefore very rare to have a wine whose analysis shows a null result. The winemaker will generally indicate "contains sulphites" to be in accordance with the Law, even though its wine will not have received SO2.
