Home Distiller

OK so i want to do a stripping run of my first generation of UJSM and i just had a couple questions.
Im going to be using a Brewhaus 30qt pot still with a bayou classic burner

For the stripping run i want to run hot and fast, discarding the first 200ml then collecting down to about 25%abv, my question is does it matter what the temp is at the top of the column during the stripping run?

Im basically wondering if its ok to just leave the burner on like medium to high heat and just ignore the thermometer at the top of my still and collect everything

Thanks for the help

Yes, run it that way. You are not interested in temps, just in stripping out the booze from the wash, quickly.

Most run pretty much as fast as the condenser will knock down, also being careful not to scorch the wash.

Thanks Husker, damm you respond fast lol

i used a still like that for my first still. i needed to build another condenser to keep up with my burner as the condensers are a little small

I did my stripping run today of UJSM and it went as such, any comments or advice would be greatly appreciated;

Turned the burner on very high heat to get the mash up to temperature, it took about 30 min to get up to 60C at which point I put on the cooling water.

The temp at the top of the column began to quickly rise and when it hit 78C I turned the burner down to a medium high heat.

At this point I had a very steady stream of warm distillate going and the temp at the column head rose to about 95C and remained around there for the rest of the stripping run although i tried to ignore it as much as possible.

For roughly 2 hours I collected from 65% down to around 25% and managed to collect over 2.5 liters from a 25 liter wash.

This wash was an UJSM first generation but I used turbo yeast so i dumped all the backset and the spent corn and will be starting a new batch. I saved the distillate and plan on adding it to my low wines from future UJSM stripping runs.

You don't happen to have any plans or pictures of that new condenser you built do you

Turbo yeast could affect the flavour of UJSSM, I get the same quantity of product using bakers yeast, without the off flavours of turbo.

Steve, the backset was probably 'fine'. It is the yeast bed (i.e. the crap still living) which will probably not be ideal from a turbo yeast in UJSM.

The backset is sterile. There is certainly better 'quality' backset, from better washes, but what you had would have probably done fine for starting out a new batch of corn, and new 'better' yeast. Now, you will be back on gen-1 again when you get your new run started. If you would have kept the backset, you would have had a 1st gen wash, but it would have been sour to start with (probably 1/2 way between a true first gen, and 2nd gen).

But have patience. This recipe is a good one to build up a BIG stock of spirit, and keep you from having to get commercial swill.
