      40% abv. at least because I can know longer work around my considerate it without getting a buzz from those fumes.  There is most likely a little alcohol in the ice after its pressed, but I am able to recover most of the free liquid.  At this time, 23 oz. of  considerate is being stored from sample 12/16/12, and it will be interesting to see how much water remains after my first striping run.  This sample tested at 10 proof at 35 F, and all of the other samples tested at "0" proof at 35 F.  It's not a true reading, but it gives me a future reference point.  

      Another thought, do I really need to drink if all I have to do is open a jar of considerate to get a buzz?

      I freeze distill only to reduce storage capacity until a still can be obtained.  Freeze distilling will stop once a still is available unless there is an unforeseen  benefit to freeze distillation.

      You have to know the freezing point of each alcohol and solve the math for the eutectic state of that solution. Since many of these alcohols freeze in the -70°F range you probably aren't going to be able to do it at home. Accurate fractional freezing requires the math and knowledge of the items in solution.  Freeze distillation is essentially the opposite problem of solving for your azeotrope when regular distilling.  Since ethanol is soluble in water, you probably will see a limit around 40% abv in a regular home freezer. The colder it gets, the more ethanol that's being trapped in your ice water, and you'll end up throwing away much more than you could distill out by volume. It's fun to play with booze though! 

      Again, if its just about storage, then sterility and keeping it closed up until ready to use, is the easiest way to store alcohol indefinitely.

      Thank you for this info, and you are correct about everything that you stated pertaining to Freeze Distillation.  Those possible dangers are why I have not tried consuming my concentrated wash.  My future plans include processing my concentrate through a still, which I hope to acquire in January to further my experiments.

      Freeze distillation is very labor intensive, but my wash samples need to be reduced for storage until they can be processed further.  Since freeze distillation is an interesting process that allows for the removal of water without the dangers of explosions, my experiments will review whether or not freeze distillation offers any benefit to the production of Ethanol for use as spirits.

      I am new to distillation, so my experiments will wander in many directions to obtain answers to my many questions.  In my readings, there are a minimum of 6 different types of Monohydric alcohols with different boiling points.   Can freeze distillation be used to remove some of these unwanted alcohol compounds from wash prior to distillation?

      I thought it might do good to recommend reading about freeze distillation.
      There are quite a few write ups available on line. One of the easiest to understand is at home distillers dot org wiki page. A simple web search can lead to many good reads.

      Freeze distillation has been used ever since fermentation got noticed thousands of years ago. It's not a new discovery by any means. There are a lot of good reasons not to rely on the final product. A bad hang over is nothing compared to toxicity from ingesting acetone or methanol.
      Even as a method to concentrate a ferment before distillation, freezing allows a certain percentage of ethanol to get stuck in with the ice. Freezing does not allow many unwanted by-products to be removed.
      I have read of a few methods that over came some of the basic drawbacks. One of which is to freeze, slightly thaw, freeze at colder temperature, raise temp. slightly, freeze colder again, and do that repeatedly until the coldest temperature your freezer can achieve is met. What a hassle.
