Are sulfites dangerous for health?
No, in general they are not dangerous to health, as we have already mentioned they are authorized by law. However, there may be people who are allergic to it, due to this reason all wineries are obliged to include a text on the back label of the bottle specifying whether or not the wine contains sulphites.
What is the maximum amount of sulfite-free wine?

First of all, it is very important to take care of the cleanliness in the cellar. A clean cellar prevents the development of bad microorganisms that can alter the quality of the wine.
Natural tannins extracted from grape skins and seeds can also be used because they have an antioxidant function.
It is also convenient to reduce the racking of wine as much as possible to prevent it from oxidizing.
