"Well lets think about the recipe first....are you gonna add sugar to your wash?

Some recipes use sugar and some dont. Plz post the recipe you want to use and someone can help you out. We dont actually cook or boil the corn, what you want to do is mash your grains to convert the starch to fermentable sugar, again if you post the recipe someone can help you out. If you heat your water to 165 and then add your corn it will pull the temp down to 150 or so and then you hold the temp there for 60 mins -- that's mashing the grain for conversion.

But if lots of corn flavor is what you are after there are several easy recipes that will suffice, good luck.Cool"

When using dried corn, the companies making ethanol for mixing with gasoline steep the corn for 24 hours at a temperature a bit above 100F before adding the enzymes to get conversion; But as heeler says. Lets see your recipe.

Im doin a 15 gal wash and I was planning on adding sugar...about 30 pounds worth of sugar...so how much corn should I use and what temp doin I need to heat up the corn to release the starch...and how long to keep it at that temp...I read that I just need to heat it up till it gets soft then cool to 150 degree and add my amylase enzyme...im goin too add amylase enzyme to convert the starch too sugar

Yes you can do that....(heat it until it gets soft I mean and go that route)

With 30 lbs of sugar in your wash converting corn starch in that wash is unnecessary really, the sugar will be your alcohol, if you want corn flavor in your distillate you can cook your corn or boil it to release the corn flavor (then toss out the corn in ur pot) and add the corny water to your fermenter with the enzymes and your sugar.

You really can make this easy on yourself and use the Uncle Jessie's Simple Sour Mash recipe (UJSSM) you can use any grain you want since you dont have a workable recipe yet, all the issues have been solved so all you have to do is follow the directions, and yes plain ole corn will work....most grain recipes call for 1.5-2 lbs of grain per gallon of water for the mash (or the conversion of starch to sugar)

Or you could try this one...
15 gallons of water (which is what you wanted)
30 lbs of sugar (which is what you wanted)
30 lbs of grain (steeped but you really dont need that much)
enzymes and yeast nutrients
the yeast of your choice (with that much sugar - distillers yeast may work better)

Hope this helps ya out some..."

Hey Taylor,

Sugar content of the corn is directly related to the starch content of your corn. If you know the starch content, you can calculate from there.

Otherwise, general starch content of corn varies from 75-85% of total dried grain weight. Note: most grain has a moisture content that needs to be factored in as well.

20lbs of corn
10% moisture = 18lbs of corn dried x 80% starch = 14.4lbs of starch

14.4lbs of starch can theoretically be converted into 14.4lbs of sugar, if you are really good with your enzymes. Most likely you will get less...

Cheers!
