AH, Bill. Well you make a mash (pun intended), and then to rack it, you just kick it where it hurts.... Just Kidding!!!
When your fermentation has ceased, and the trub (yeast, grains and such) has somewhat settled to the bottom, you take a racking tube, a siphon (Brewhause has an excellent ss one, that I use) and rack, siphon off the more clear liquid into another carboy, for further settling and clearing. Then when clear again rack into the boiler. Some as I almost do, except with fruit brandies, just wait till its all clear and rack the one time. That racking tube is a must have, though there are other ways some do it. Ball valve near the bottom etc.
When you make your spirit run. Cuts...
First the foreshots- methanol and other really low temp. products.
Heads. These are mostly lower boiling point alchahols that would taste and smell like fingernail polish, and is what will give you that wonderful headache and hangover with a lot of the store bought hooch. Upset stomache included. It contains a lot of good ethanol so save it to the feints jar. Now you will collect the hearts, hopefully proper cuts it will be 95% ethanol. Then the temp will start to rise a bit, which indicates you are getting tails. These are oils and higher boiling point alchohals that have smell and tast like wet newspaper. Collect all these and add to the faints jug.
When doing the spirit run, collect into small jars and number them. cover say a pint each with a coffee filter and ring to hold it there or other jars you choice. Let breathe and cool for at least 24 hours. Then by taste and smell, combine the good ones. The rest to the tails. Nothing wasted as you will distill these later.
That was for neutral. For a flavored grain, do exactly the same in pot still or way weakened reflux mode and combine for taste. For whiskeys you will want enough of the latter heads to give flavor. The airing and rest really helps there. For rums, certain tails are important.
As I think Wade suggested check out home distillers . org. Kinda an encylopedia of the art.
Have fun and rack those mashes.
Bill, order or go to the library ang get Ian Smiley's book ""MAKEING PURE CORN WHISKEY""."
