Answers.Text: Thank you very much. Get a number of keywords to study. Us I understand Acetic Acid is present in every brewing process (at least of berry wine brewing) since there are a lot of tests in the shop to control it.

  First thing, pick up a basic winemaking book. All of this is covered in there.
  
  If you have an Acetic acid problem, then you have vinegar not wine.
  
  If you just have high tartaric acid, you can do a two things. Cold stabilization and potassium bicarbonate. Cold stabilizing is putting the wine in a freezer at about 25 degrees for a couple of weeks. I usually do this naturally on the coldest days of the year. Tartaric acid turns into tartrate crystals and sink to the bottom. Also, you can add Potassium Bicarbonate and it reacts with tartaric acid and reduces it. You'll have to do some research here.
  
  If you have a malic acid problem, then malolactic fermentation is a way to turn the harsh malic acid to lactic acid. Again, consult a winemaking book to figure out the details.
