White House Apple Cider Vinegar

Well my beets are almost ready to pick and I want to pickle some.  I emailed White House to see if I can safely use their Apple Cider Vinegar. 

This is what I said: 

Could you please let me know if you use any kind of citric acid or any other corn derivative in your apple cider vinegar?  You can go here to see if any of your ingredients maybe made from corn:  http://www.cornallergens.com/list/corn-allergen-list.php

This is about me:  http://cornallergyaid.blogspot.com/

I will post their response when I receive it.

The response:  They say the apple cider vinegar is made from just apples and water.  No other ingredients. 

I think I will have to try it.
