Sorry for missing this post, I used to grow golden Bantam and for a sweet corn its not so sweet and its kinda tuff, chewy. Ma used to say it would be a lot tougher with out it.
A better non hybrid corn is Ashworth.
When I grind sweet corn, I use a cast iron burr grinder. You have to make sure that the corn is very dry as moisture tends to make the corn build up on the burrs. It makes a course corn meal.
If you have lots of corn to do, I use a Black Beauty corn sheller, saves on the hands. Save the cobs for smoking your hams.
For winter wheat, I use a stone mill. It makes a nice flour as does buckwheat.
