Thats a good question. I can't find much in their literature. Shoot them an email and see if they will tell you what the parent strain is. From their documentation:
OENOFERM® C2 | 500 gOenoferm® C2 is a dry selected yeast for fermentation of grains, molasses, potatoes, as well as fruits. It adapts well to high gravity media and high fermentation temperatures. It has a high alcohol tolerance and ensures low formation of flavour components.
I would not choose it for corn. They recommend it for vodka and neutrals.
