Hi, I have two 4000L ciment fermenters that had infected wine from 10y ago.. how can I clean and disinfect them totally to make "good" wine again?
Asking to different people in the industry opinions divide between:
1. Clean and disenfect them with phosphoric acid. Cover the interior of the fermenters with epoxy.
2. destroy everything and buy new inox fermenters because option number one will still turn your wine into vinegar.
What do you think?
