So, wine is slightly acidic, we all know that. My theory is therefore to make "wine salt".
"Wine salt" is the product of a reaction between wine and a base, in my case sodium carbonate. This will produce a salt with the acid in the wine.
But I have some problems. What is the acid in wine? Is it acedic acid (because wine makes vinegar and vinegar has acedic acid in it) or something else? And what base could I use to make the "wine salt" edible?
