"Welcome Ozark Paul, Its a good place to ask questions and learn and share.

I'd like to make a suggestion that you might try for your horse feed. Perhaps try doubling the grain volume and since you are heating it anyways, then add at least 20% of that of malted barley. The enzymes in the malt will convert the starches in your grains to sugars that can be fermented. This will greatly increase the amount of good drinking per run and somewhat increase the flavor also. If that works for you and you like the outcome, you could triple the grains for the next run. Without a boil this won't convert the corn much, but will some.
Another trick you might enjoy is sour mashing your runs. This is useing about a gallon and a half of the leftover pot stillage from the previous run to the next. This increases the flavor and lowers the ph so the enzymes and yeast are more efficient.

Welcome abourd."
