    90%abv is relatively easy to produce in a compound still - you need a reflux condenser in a fractionating still to get that extra 5%abv. wal

      >   There are many various designs for stills, as the saying goes - Necessity is the Mother of invention.  Work with what you have and experiment.  All that is necessary in a reflux still is that the vapor has to condense over and over inside the column.  As the column heats up, the vapor will climb through the packing toward the top and eventually will spill over into a condensing unit.  This condensing unit doesn't have to be at the very top.  You can incorporate needle valves close to the top of the column and siphon off a small portion of the product while the rest is directed back into the column for further reflux.

      > > >my still is a 15 gallon keg, with a 1.5"x3' column. should I be monitoring the temperature up at the top of the column right below where the condenser comes off? also, with a 3 foot column, should I really bother packing it with copper scrubbers, or do you think just because of the height of the column, i will get a little bit of reflux. any and all advice would be muchly appreciated. even if it doesnt have to do with temperature, all advice is awesome since this is my first still.
