Although not legal in my area, I know a really really good friend who has built himself a very nice still. It is a vapor managment still and can produce 95%+ neutral alcohol (vodka, except his recipe doesn't include grains so it does not meet the government's description for a vodka)
His equipment includes a 15.5 Gallon SS keg with a 3" Diameter, 5' high column and 7500watts of elements with a home built controller which allows 0-7500watts. He can produce top notch neutral at about 1L every 15-20 mins, this is after about 5-8 hours of bleeding fores and heads. Mash recipe is simple, 28kgs Cane Sugar, 4tbsp Citric Acid, 1500Ml Tomato Paste, 908G Bakers Yeast and then topped up to the 280L mark with well water(which I have no idea on the chemistry of other than its on the softer side for well water and is bacteria and chemical free)
When said and done (there is quite a bit of time involved, 16+ hours easy) This results in about 17L @ 95% neutral ethanol, knocked back to drinking strength your looking at near 40 quarts as they are called here(Canada) but are in fact 750ML bottles of a very very drinkable booze, better that most top shelf vodkas you can buy. Unfortunately this is an illegal hobby in Canada (and the US I believe) but if you are interested in gaining more information on the subject http://homedistiller.org/forum/
and http://www.artisan-distiller.net/phpBB3 ... dda92bb74d
will have you reading till your eyes are bleeding. Enjoy! If my friend can find some pictures of his "tools of the trade" I will see if I can post them. This is an expensive hobby to enter and you will want to be a plumber/pipefitter or know one for the best deals as copper is EXPENSIVE!
*Edited to add: Booze where I live is expensive, a quart of vodka (750ML) on the cheap end cost $22CAD on the low end, top end bottles of vodka (Grey Goose, Effen, Etc.) are over the $40CAD mark. What I buy when not "bumming
" is Russian Standard Vodka and this costs me $25.49CAD for a 750ML bottle, which I consider ridiculous, but is a sad fact of life where I live
