45039RE: [new_distillers] Mashing
- Apr 17, 2014Jerry,
From my own personal experience, boiling the corn to gelatinize the starch crystals makes the biggest, gummiest, mess of all, but there are a couple of ways around making epoxy/corn/gum. Adding some ordinary enzymes (either store-bought or from malted barley) to cold water and grain will hydrolyze a lot of the gummy stuff on the way up to boiling temperatures (I think it's called pre-malting), even though the enzymes will be denatured finally in the process. The rest of the process is the normal cool to 152 and then add final mashing enzymes.
A super variation on that is the get some of our own Pint-o-shine's high temperature enzymes, and reduce that corn to liquid, and the starch to dextrins and then to sugar, all in pretty much one pass. This video is a real eye-opener to anyone that's fought the dreaded corn gum/goop.

3 gallons of water for the mashing. After I had converted the starch to sugar, the mash mixture was diluted with water until I had a grain and water volume of 16 gallons. That was what I fermented. I got the recipe from the archives quite a few years ago. The recipe also included the mashing instructions. It warned about how thick the mixture became and how essential the stirring was. I did several batches like this.Once the corn started converting and the grain absorbed a lot of the water, the mixture was so thick that it took extreme effort to keep it stirred and from burning. I had to throw away one batch due to burning. My attention had wandered momentarily because I was so tired and that was all it took to burn the mash. The entire mashing process took 8+ hours per batch. I did end up with about 8% potential ABV without adding any sugar.My thought was by boiling the starch from the corn, I would halve the amount of grain that I would be mashing thereby keeping the mash from being so thick. If the mash was thinner then stirring would be easier and less chance of burning.Jerry McCullough
