Grain based recipes, the real deal!
Various details regarding the production of grain based alcohol is described in the section "making the wash - grain based".
Note: Bear in mind that you can forget about distilling grain based washes, if you are using a still with an INTERNAL electrical heating element which is mounted inside the boiler! If you have the boiler in a water bath (Aub Baine Marie), it is not a problem.
You will have too many solids remaining in the wash that will burn onto the element. The alcohol will have a bad flavor and odor, which you can not remove/polish out. Also it will be difficult to get the element cleaned up after distillation.
