IMHO, it depends on the flavor issue. Vinegar will add its own flavor to the cheese, while salt is a normal ingredient. I know, I know - distilled vinegar supposedly doesn’t add flavor - but I personally don’t like the taste of vinegar. Also, vinegar will add acidity. I’m not sure of this either, but I don’t think acid level affects mold growth - its pretty hardy stuff. So, whichever you do, it has to be done regularly.
Brine kills bad bacteria allows good bacteria. Vinegar kills all bacteria. So depends on what u want to accomplish. If u do a vinegar wipe then once should do.
LOL, Guess we need to have a legend to describe what bacteria/enzymes etc is so we speak the same language and have the same meaning I know I interchange words without thinking sometimes.
