  1. Sediment in finished bottles

    Very likely a flock is forming after filtration. I see it a lot when cutting below about 45% even as high as 50% I have been lead to believe it is oils and proteins that were dissolved in the high strength alcohol, but at lower proof they come out of solution and eventually form crystal masses, ie cloudy. This eventually settles on the bottom of the container. Shake it up and crystals break up and vanish but usually re-form. 2 ways to overcome it. Chill filtration or time will allow crystals to grow large enough to filter out. Or allow about 6 weeks for crystals to settle to bottom of tank. Don't bottle very bottom of tank.
  2. ABV of finished sugar wash

    If the Brix is being read with a refractometer then a zero reading means there is no alcohol or sugar in the sample, only water. The hydrometer reading of zero is also confusing. An alcohol hydrometer in water at standard temperature will read zero if there is no alcohol or sugar present. Maybe you mean an SG hydrometer and you actually mean a reading of 1.000 More information required please.
  3. label printer

    I have a cheap desktop thermal TRANSFER printer. Being a TRANSFER it will print onto normal paper. For small runs of labels I get commercially made labels with blank spaces to add details of the specific product. Thermal transfer needs to print onto a very smooth paper otherwise the print is not very sharp.
  4. I will build my distillery from ground-up. But I need HELP!

    I haven't checked the numbers but you say "Hence, a total of 870000 BTU is required to vaporize all 500 liters of this mixture." When distilling alcohol you do not vaporise the whole 500 liters. If you did you would end up with the same ABV that you started with. You only need to boil off about 1/5 of the volume. By then there is no alcohol left in the pot Maybe you have not explained properly but you appear to be starting with a 40% ABV in the pot. I would assume there are no solids in that so you could go direct fire and save all the work building a steam boiler. BUT 40% in the pot is pretty high and could be dangerous with direct fire even with bain marie jacket. Cut back to below 30 % to make a little safer. That might not be what you are trying to achieve so please explain in more detail I suggest you spend some time at a small distillery before you go any further.
  5. Dephlegmator and Condenser Equilibrium

    That pretty well kills my theory then. I didn't see any mention of altitude and that is why I mentioned sea level for the common boiling point curves
  6. Dephlegmator and Condenser Equilibrium

    I have a possible explanation. If your pot temperature is 182f that indicates your ABV in your pot is close to 50%abv but you said 9.5% (see graphs of boiling point vs. ABV at sea level) If the temperature sensor in the pot is above the liquid I have observed that it reads lower than if it is submerged. As your run progressed you have a higher % of solids and there may have been a buildup of foam that eventually reaches the temperature sensor and suddenly your temperature reading goes up because the foam temperature will be close to the liquid temperature. Regarding a possible leak in your condenser the symptoms you gave make that very likely. If your condenser water is exiting the pipework to a drain well below the condenser then there will be a slight vacuum in the condenser. A hole in the coil/jacket will "suck" some of your alcohol vapor or condensate into the cooling water and you wouldn't notice anything except low yield. As you applied back pressure on the condenser water it would push cooling water into the alcohol side and your ABV drops as observed. Easy to check with cooling water on and still switched off.
  7. Off hearts to trails ratio

    Do you intend to do 2 runs? this stripping run then a spirit run? If this is the first run, you called it low wines run, then I suggest you don't do any cuts. Do them on the spirit run only. With only 2 plates treat it like an alembic pot still.

  9. boiler

    If you can get enough used hydraulic oil that would be the cleanest and easiest energy. Fitting an oil burner to your wood boiler should be very easy, possibly not maximum efficiency but fuel is free, or almost. A lot of equipment required for a round bale boiler
  10. boiler

    I am running my still direct fired with waste veg oil burner and heat water and steam with waste oil. My Son is also using waste veg oil burner for steam in his brewery. http://www.econoheat.com/waste-oil-equipment/hot-water-boilers/ US company in Washington We only have their burner guns, not their boilers. My hot water/steam boiler was originally a wood fired boiler, just took the ash drawer out and put burner gun there. My Son gets his oil from a fish shop that runs it through their filter before dumping back to original drums. All ready to use. I need to filter mine to about 120 microns. I believe used motor oil may require less maintenance of burner gun but it is not as pleasant to handle. A bit more maintenance than gas, and possibly filtering, but FREE fuel Econoheat also have wast oil powered chillers http://www.econoheat.com/waste-oil-equipment/air-conditioners/

    Fermented mash eats aluminum, I know from experience

    Tom, I am in no doubt you are correct, I am just trying to point out an easy to see mistake in the TTB wording that is open to interpretation by both distillers and TTB agents. "entered at" and "stored at" have different meanings and can have very different end results It is little wonder that different TTB agents will give different answers (did one say run the spirit through an oak trough then it is whisky?) If the answer suits you then get it in writing.

    I think you are correct, but that is not what the wording says in BAM pdf, it says "stored at"
  14. pH Raising Agent

    I was doing an experimental batch with very high % of acidic stillage so I would have used way more NaOH than normal. Once distilled I didn't detect that alkaline odor.
  15. I would be interested to know peoples thoughts about the following tps://www.ttb.gov/spirits/bam/chapter4.pdf RYE WHISKY³ Whisky produced at not exceeding 80% alcohol by volume (160 proof) from a fermented mash of not less than 51 percent rye and stored at not more than 62.5% alcohol by volume (125 proof) Last week I bottled a barrel that I filled several years ago with spirit at 61.3% On testing, and re-testing, the whisky is now at 68.5%. The Angels Share has removed more water than alcohol which is usual at my distillery in Tasmania, no issues with Australian regulations. But if I was in USA under TTB it has been stored for some time at more than 62.5% What implications would that have to you guys?
