  1. 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.

  3. 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
  4. 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
  6. 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?

    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"
  9. 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.
  10. White Whiskey

    That is the page I was looking at. I assume BAM is the equivalent of "Fake News"
  11. White Whiskey

    OK, but why does the TTB page that I quoted differ from the one you have just quoted??

I presume you have to write on label ".. from...malt mash"
  13. pH Raising Agent

    I have tried it but it produces a strong alkaline smell in the ferment. How concentrated is the NaOH when you add it? If I use it again I might try diluting quite a bit.
  14. White Whiskey

    I am an Aussie so I don't need to follow TTB regulations, but I always thought you had to age whiskey and bourbon in NEW oak containers. Also to offer an answer to the stick or stave suggestion, they are not containers, a container means you put the liquid into a space that is surrounded by oak, not liquid surrounding the oak. A hollow wooden cube is a container, I assume it doesn't need to be a barrel or cask.
  15. On The Grain *Newbie*

    Is it a really nasty burn or a light scorch? I know peated whiskies are not so popular in US but a light scorch can be a pleasant alternative to using peat. Also only 5% malt, that may be a bit light on to get full conversion,
  16. Small Scale Grain Liquid Separation

    Intrigued. Why do you think malted corn can be sparged? and why would his method "not be allowed today"? I have my theories on the sparging which I will post when I get time, have staff arriving right now.

  18. Small Scale Grain Liquid Separation

    This type will work for high % barley grist but not if high % fine ground cooked corn. A sloping screen is the simplest. Scrape the solids off as they build. There is another thread on this subject.
  19. Lab distillation of very high-solids liqueurs

    Thanks meerkat, I have forwarded this discussion to John, not sure if he is a member but he can at least read the thread.
  20. Lab distillation of very high-solids liqueurs

    I had a call yesterday from a friend who was finding the opposite of what he expected after lab distillation. He makes absinthe. Normally with a spirit containing sugar a hydrometer will float higher and indicate a lower ABV because of the higher density of the sugar. Lab distillation removes this sugar-solids-obscuration and the hydrometer will show a higher ABV He measured the absinthe directly with a hydrometer and calculated the ABV Then did a lab distillation and got a lower reading. I am sure he did the distillation and calculations correctly. My feeling is the substances in absinthe that are causing obscuration have a lower density than ethanol. (oils?) Any thoughts?
  21. Proofing Issues

    Air bubbles can also make the hydrometer float higher if they get attached to the bottom of the hydrometer, spin the hydrometer to shake them off.
  22. Tank aging of fruit/berry based Liqueurs

    I recall a presentation at an ADI conference in Louisville about 5 years ago. A researcher from Tuthilltown was giving great detail about "molecular clustering" of ethanol. Over a period of time the molecules attract to each other and form clumps that trigger a more mellow sensation on the tongue. That presentation was about ethanol only, maybe other flavour compounds clump as well.
  23. Lab distillation of very high-solids liqueurs

    Your findings do not surprise me at all. I have often measured lower than expected ABV and suspected heating the flask contents once most of the alcohol and water have gone would most likely boil off solids, which will then cause obscuration of the collected distillate. I have been tempted to re-distill the distillate to see if this was happening. Your method would be easier and probably more accurate.
  24. In pot mode you definitely need to run it twice as mentioned above. A single pot run will always taste like tails.
  25. Please take this suggestion with caution. I put some of my heads in a garden sprayer, one with an air pump on the top. I can then spray this into the flame of one of my waste oil burners. One caution here is if the nozzle gets very hot the plastic parts could melt. As mentioned in an above post the burner under my still has dual nozzles so I can run one with oil and the other heads. I have tried mixing heads with waste veg oil, it will blend quite nicely but eventually splits out again. Have tried various types of detergents but haven't managed to form a permanent emulsion.
