    Wow, you really are speaking to me as a chef. I found your channel like a week ago in my recommended because I was trying to learn about distilling, and you’ve already improved my tepache and today I was looking to make an ancho truffle and found this video. Combining two of my own current culinary experiments into one dish is incredible. The algorithm is listening too well and putting my eyes right on what I want.

    This is so awesome! I’d love to get into re-distilling like this.
    I’m curious, when using a base spirit like Vodka, do you not have to worry about heads and tails like with traditional distillation? Is there no methanol to worry about?

    Eddie........ this is fantastic! I find I’m excited and inspired by each video I’ve seen. In response to your request I thought of a plant I’ve been looking at quite a bit lately for its many uses and benefits. Its also considered a scourge of a weed in some contexts. By name: Mimosa (Portugese), Acacia Dealbata . I’d be curious as to your perspective, ideas in uses and processes of value.

    would be nice if you explain what you put in (is it already distilled once to get rid of the methonol and acetates) , what you get out and what quantity of say gin you would get and how you blend it, sound like a load of work for very little alcohol to use.

      If you look at my most recent video on the rotavap from an about 2 months ago I cover all of that I think. And I have a specific video on making vacuum distilled gin from last year which goes into lots of detail on making gin and again answers these questions, hope that helps

    expanding on the ability to remove aroma from scotch bonnets. Can i use any of the equipment in this video or other videos you have to remove the capcacin from peppers but keep the flavor and aroma for cooking? Theres so many fantastic peppers that have amazing flavor, but are too spicy to try and use multiple in the same dish.

    If you vacuum seal alcohol using vacuum wine saver, would this increase evaporation?

      I'm not 100% sure what a vacuum saver is. I imagine like a zip lock bag for freshness lol.
      Heat and pressure increase evaporation, if your not adding heat or reducing the pressure. No impossible

    How was the distilled koji? How’d you use it?

    • @EddieShepherd
      @EddieShepherd  ปีที่แล้ว

      I have used it in a few trial dishes but nothing that has made the menu so far. It was interesting adding it to amazake add alcohol content and accentuate the koji aromas already in that. It was very pleasant but fairly subtle in aroma, very much as the smell of fresh koji is. I think if I do another batch I will use a higher percentage of koji and maybe do an ultrasonic infusion too before distillation.

    • @EddieShepherd
      @EddieShepherd  2 ปีที่แล้ว +2

      I drop the pressure to close to full vacuum, and generally distil at 35C - 40C (35C for the most delicate ingredients)

    So, this apparatus infuses flavors with alcohol. It does not create alcohol from sugar vapors, like an actual still?

    • @EddieShepherd
      @EddieShepherd  ปีที่แล้ว +2

      It doesn’t infuse, you infuse the alcohol first then use this to re-distil it. You could use it to distil alcohol from fermented sugar but it wouldn’t be the most efficient way to do that and there are stricter rules about that. Most people use them to re-distil infused alcohol at low temperatures

    Could you use this to remove alcohol to make a NA neutral spirit

    • @EddieShepherd
      @EddieShepherd  2 ปีที่แล้ว

      you can distil alcohol off a liquid and thereby remove alcohol from it, but neutral spirit is basically alcohol and some water to dilute it, if you distill off the alcohol you'd basically be left with water and some impurities etc so I cant see a reason to do it.

    Nice introductory... I've had a mind to extract some pretty off the wall flavors for a unique gin, and this inspires me...
    There are a million units to choose from... Can you point someone in the right direction for a reputable manufacturer?

    • @EddieShepherd
      @EddieShepherd  3 ปีที่แล้ว +2

      It’s a perfect way to make a really unique gin, and you can get really experimental with the flavours.
      I have the Buchi and have their cheapest model which is great for me. I went with Buchi because they have a great reputation & I feel they are reliable & consistently high quality
      I think my model is the R100, I love it!

    In your rotavap distillations do you do anything special to lessen or prevent methanol product or is that even a concern here? Thanks!

    • @EddieShepherd
      @EddieShepherd  ปีที่แล้ว +1

      Hi, in short it isn't a concern with the distillation I am doing as I am re-distilling a neutral grain alcohol which has already been distilled before I infused my chosen flavours into it. Methanol is produced during fermentation, so if you were fermenting your own base to produce alcohol and then distilling it what would be something you would need to manage, but with a clean, pre-distilled neural grain sprit as a start point (how most gin starts) you dont need to worry about that, the methanol is already removed. I then infuse in my flavours or combine them depending on what I'm making, re-distil that mixture at low temperature for flavour purity and then I can use that finished distillation in the way I want. Hope that helps
