      I have told you about my sample dated 11/29/12, and 1 tbsp. of garlic was added to see if it would kill bacteria.  After a month it's still crackling away (fermenting).  This sample started with 1 tbsp. of yeast, and it was re-pitched with a second tbsp of yeast.  Not only is it strange that it's still going strong, but a second sample dated 12/02/12 is also going strong.  2 other samples started after have already been processed by freeze distillation.

      The only thing that makes any sense as to why those 2 samples are still fermenting seems to be the low amount of yeast used in those two compared to my most recent samples.  12/13 and 12/16 both used 21g of yeast and were re-pitched with another 7g or 8g of yeast.

      My 12/24 sample started with around 35g of yeast, but more sugar than all other samples.  If 12/24 burns out fast, then the only reason why samples 11/29 and 12/02 are still fermenting is the lack of yeast.  If this proves to be the case, I will need to add much larger amounts of yeast so that it will not ferment longer than 2 weeks.

      Hi I am Henry and have been using these processes for some time. I have used the freezing process and it works well with concentrating the wash, the only downside is it seems to remove many of the volitatle esters used for flavoring, but this isnt a bad thing for vodka or neutral spirits though. Remember the nasties are still in there ( MEK ect.)and need to be gotten rid of before drinking.
      LOL I have had problems with potential ABV in the wash and gave up trying to measure, I just use the initial calculation and go from there.

      Ah, that would most likely mean that all of my readings with my alcohol proof meter are currently way low on my concentrated wash, and I need to get my other meter out of storage. I am doing my freeze distillation process differently now.  If I am correct that ice crystals will form in Ethanol with a low enough temp, my wash should be able to be reduced even further than ever before using this process.  20% abv. or greater would be fantastic for storage.  Several more experiments are required before moving on to 16% and 20% abv. yeast.

      You need a brix or plato hydrometer.
