Can someone explain what went wrong ( malted corn)

[Malticulous]

The American Handy Book of the Brewing and Malting mentions all malted corn beers but says that they had a disagreeable flavor.

Here is a link to all corn malt beer thought that this would help.

Also done a lot of reading on the subject and have read that corn malt have enough dp to convert itself but not as much as barley.
Hope that this help.

If the overall temperature of the grain went above the maximum temperature for the enzyme, the enzymes will have been deactivated.

A quick google shows that folks air-dry the corn once it has sprouted, usually using a fan.

You may want to try it on a smaller scale, say 4 or 8oz and see how it goes.

Pretty much. Didn't sound allthat scenic.

Now that there is funny I don't care who you are

The native Americans did air dry the malted corn.

How much corn did you actually use? I am fermenting up a 5gallon batch right now, and I got OG of 1.048 with 14lbs. And only about 5 of that was malted, the rest cornmeal and sugar.
When the corn sprouts are about an inch long, there should not be any starch left in the kernel. It will have all been converted to simple sugars for the baby plant to consume while its breaking the surface of the ground in search of the sun. The enzymes should still be there though, that's why you can use cornmeal. They will break up the starch in your boil, provided its not too hot to kill them off. Be forewarned, the meal makes a big mess to clean up afterwords.

FYI, when drying your newly malted corn, do not let the temperature go above 130. Anything higher will start killing off the enzymes. If you have the time, let it air dry in a sunny area. Also, when when heating on the stove, keep your temp between 140&150. The enzymes will die off at higher temps, and try to keep your boil around 45 minutes max. Again, the enzymes start dying off at boils longer than that. Hope this helps a bit. It's all the special info I've been able to come up with in my trials

thanks for the info.....brewing has been on hold.. I have a few gallons of different things setting in the ferment room that have ben done for months and just need kegged...havent even done that yet.

in case no one has recommended this yet corn malt is rather delicate, if you want to ensure proper conversion do not dry it before the cereal mash, dryed corn malt will have a dp of 40 at best and typically much lower due to excessive temperatures during drying, but wet it can have a dp in the 200 range wet malt is always more potent

Just in case anybody stumbles across this needing an answer. Corn can convert itself easily and when using 100% malted corn you can also convert an equal amount unmalted corn (1lb. Malted 1lb. unmalted). I’m thinking when drying and mashing you’ve heated it way too high denature gets the enzymes so you have only the sugars converted prior to this and no power to convert anything else. You have to keep the temp under 150 Fahrenheit once the grain has sprouted. You don’t need any other grains except corn, like I said before it can convert itself without issue. People have made moonshine for years with only corn around the area I’m from. If you have any doubts you can find science to back this.

@Seth999 please explain....have you personally done this? the geling temp of corn is above the denaturing temp of amylases.....the only way i can imagine doing a 100% corn brew would be to do a cereal mash, then cool to strike temp, for an additional addition of corn malt?

By law to be labeled "Bourbon" the liquor has to be at least 50% corn. This tells me that at some point people were using less corn and a wider variety of grains to make what was called "bourbon". If they were using less corn I expect it was to enhance conversion efficiency.

If they were using less corn I expect it was to enhance conversion efficiency.

no, it was the revolution.....as far i've heard from the history channel, they started using corn, because the king and stuff with barley....gots to get your drink on to fight the king!
