Yeast or vinegar dried grains are the dried residue from 

 the mixture of cereals, malt and malt sprouts (sometimes 

 cottonseed meal), obtained in the manufacture of yeast or 

 vinegar. They consist of corn or corn and rye, from which 

 most of the starch has been extracted, together with malt 

 added during the manufacturing process to change the starch 

 to sugars, and malt sprouts (sometimes cottonseed meal), 

 added during the manufacturing process to aid in filtering 

 the residue from the wort and serve as a source of food supply 

 for the yeast. They are probably similar to dried distillers' 

 grains in feeding value.
