Specialist Questions - Spirits, Essential Oils, Vinegar

Would you like to ask us about spirits, essential oils and vinegar? Please observe our forum rules (see Helpful tips for use).

June 2018:

It has now been an unbelievable 16 years (!) since the last major change to the website and forums. When you think that two to three years are an eternity for the Internet sector, that is really something. In any case, there has been so much going on in terms of technology that it has become urgently necessary to completely redesign not only the forums, but also the entire website, from scratch and bring the programming up to date. Naturally, along with this we also introduced various new features; for example it was high time we allowed pictures to be uploaded with a forum post too or enabled users to subscribe to the forums via RSS feeds. And of course we have subsequently included pictures that are saved on external websites and were then integrated here using an img tag, so that no valuable information is lost. In any case, we hope you continue to have fun swapping experiences and trying things out.

Juni 2002:

At this point, we would first like to extend a big thank-you to all the users of our specialist questions for their lively involvement. Without you, we could never have developed such an informative and high-quality reference guide in such a short time (the first post dates from April 8, 1999). The large number of posts and high numbers of visitors made it necessary for us to develop the specialist questions ourselves using PHP and MySQL (at last no more annoying advertising banners!). During the course of this, we have hopefully introduced several improvements.

RSS-feeds

The latest entries in all the forums can be conveniently received via RSS feeds. You have the option of subscribing to RSS feeds in your browser, accessing a special feed reader, or displaying the feed on a website. By subscribing to or integrating an RSS feed,you receive short information blocks with the last 10 entries of the forum you have subscribed to. To find an RSS reader, simply google “RSS reader”. Here are two examples of add-ons to the Chrome browser: Feedbro, offered by Nodetics https://chrome.google.com/webstore/detail/feedbro/mefgmmbdailogpfhfblcnnjfmnpnmdfa?hl=de This reader does not require registration. Or RSS Feed Reader, offered by feeder.co https://chrome.google.com/webstore/detail/rss-feed-reader/pnjaodmkngahhkoihejjehlcdlnohgmp?hl=de Available for Chrome, Safari, iOS and Android, registration required. To receive the feed, click on the RSS icon on the right, above the forum, under “Enter search term...”.

Helpful tips on use:

Below are a few rules so we can maintain the high quality in the future as well.
  • This is a moderated forum. This means that anyone can write whatever they want, and the post will also be saved, but the content will only be published once it has been reviewed by our editorial staff, or deleted if necessary. Therefore, there is no point in posting the same contribution multiple times simply because it doesn’t appear immediately.
  • If you would like to see the most recent posts (irrespective of the topic), click Show the latest posts.
  • The forum is very comprehensive, and many topics have already been dealt with extensively. Therefore we recommend using the search function or alternatively the advanced search function before you add a new post in order to avoid having posts with the same content.
  • After you add or answer a post, you then have a chance to change the text you have written. So read through your text again carefully after saving it and click on “Change post” if necessary.
  • If you ask a question, then also expect an answer. Think about this as well when you are wording your question. Hardly anyone will answer vague questions such as “How do I distil schnapps?”, “No oil comes out; what am I doing wrong?” or “The vinegar isn’t fermenting, why?”.
  • The three topic areas, i.e. distilling spirits, distilling essential oils/hydrosols and making vinegar, are divided into three different websites. Each website contains the two forums “Recipes” for all the topics concerning fruit and recipes, and “Discussion” for all the other topics related to distilling spirits, essential oils/hydrosols or making vinegar. If we find posts that are unintentionally in the wrong forum, we will move them to the right forum. These posts have not been deleted, just moved.
  • ANY TYPE OF ADVERTISING WILL BE DELETED WITHOUT EXCEPTION! This also means seemingly “innocent” posts such as “I have a question about...” or alternatively “Does anyone have experience with...” followed by links or pictures to any external shops.
  • The same applies to bizarre posts which most likely come from drunks or don’t have the remotest thing to do with the topic area, e.g. football or “Where can you burn CDs here?” They will be deleted without exception.
  • All forums are STRICTLY ANONYMOUS; so never give any real names or addresses.
  • Any attempt to make personal contact will be deleted immediately.  There are now numerous social networks for this purpose.
  • The authors’ IP addresses are NOT saved!
  • E-mail addresses are not passed on to third parties or used by us in any other way.  You enter your email completely voluntarily and it functions more or less as your ID. In contrast to most other forums, we don’t require any registration or any type of login to be able to participate. Therefore it might happen that a pseudonym is unintentionally used by two people, so there has not been a mix-up in the entries.
So, that’s it. We hope you have a lot of fun swapping experiences, reading, posting and naturally also trying things out afterwards. Dr Malle & Dr Schmickl Dr. Malle & Dr. Schmickl
  • Question 14

    Amy | Pacific Northwest (US), 04.10.2024 22:30:09

    I began my apple vinegar on 9/8, strained out the apples on 9/15, and at this point it tastes like a light vinegar but I wonder if I could/should let it go another week or so. Is there any chance it’s at its peak right now? Could another week ruin it or will it just get more vinegary? How do I know?

    Thanks -

    Amy Manny

    I suppose you describe an infusion of apples in vinegar, not a vinegar fermentation. If it is actually an infusion, you can leave the apples even longer, depending on your personal taste. To enhance acidic taste, or rather to get a strong vinegar, add white (distilled) vinegar with a higher acididty.

    What are the ingredient of Digestif drinks that affect the stomach? How and why these ingredient affect the stomach whereas other liquors and alcoholic drinks such as apéritifs affect the throat? How these specific ingredients work specifically on the throat?
    Reply
    ad 1) Herbs in a positive way, undesired fermentation by-products in a negative way, e.g., nausea is induced by ethylacetate, among other substances, and after having consumed too much alcohol.
    ad 2) Herbs ingredients are healthy, good for your stomach, whereas pungent smelling drinks affect the throat, caused by acetaldehyde.

    ad 3) To avoid this issue, just don't drink alcoholic beverages with a pungent smell.

    LS | USA, 18.12.2023 04:19:50

    Hi! I have your book and love it!

    Im in the process of fermenting some satsuma juice and have noticed a bit of a yeasty smell and off flavor. im wondering if the yeast is stressed and what i can do to fix it.

    i started by juicing satsuma and grapefeuit, adding the juice and pulp to a sanitized glass jar. i added honey, about a 1/3 to the amount of juice, and then hydrated some red star wine yeast to mix in.

    fermentation was great for first few days but now im on day 5 and it seems fermentation has slowed way down. i know honey is microbial so this could contribute to slower fermentation times, but the smell and taste make me think its a yeast problem.

    would you recommend that i add more fruit juice, potentially more yeast, or just wait and continue to stir to release CO2 and hope for the best?

    I did not take a hydrometer measure at the beginning of fermentation. I appreciate your help!

    Reply
    Thank you!
    :)

    If after yeast addition the fermentation has strongly started after 24 hours at latest, everything should be in order. Your desired yeast type has taken over and killed other (unwanted) strains. It's normal behavior if fermentation speed decreases over time. Having said that, to notice this effect after 5 days already, is usually too early. But this behavior also depends on the volume of the fermenting batch. With not more than about 4 liters (1 gallon), it should nevertheless be in order, whereas with the tenfold of this volume, there shouldn't be a noticable difference yet.

    After a successful fermentation start, yeasty smell and off flavor is caused by the active yeast strain. Unfortunately, even some cultivated yeast strains have this issue. I hope this is not the case here, I've never heard anything like that with Red Star brand products, but who knows. In any case, it cannot be lack of nutrients, satsuma juice contains more than sufficient of that.

    BTW, fermenting honey by adding yeast to a honey-water-solution (or honey-juice-mixture) is normally trouble-free, especially, if the fermentation has already successfully started.

  • Question 21

    Amateur backyardigan | Arkansas, 30.06.2023 03:38:51

    Made a mash of 50% cracked corn 50% sweet grain. Checked at 5 days and hydrometer showed .990 so I decided to run 5 gal of mash. Discarded 250 ml head and next jar tastes horrible and only proofs at 90. Suggestions?

    Reply

    It seems the alcohol content is rather low, so not much alcohol has formed by fermentation. Maybe the starch wasn't properly turned into sugar and / or the alcoholic fermentation didn't perform well. Check the ratio of starch - sugar with iodine tincture, analyze the alcohol content of your mash.

    Can you send English instructions on how to use the pectinase?

    Reply
    I can't speak for products of other brands, here are the instructions for product "Verflüssiger Spezial" (company: Oestreich GmbH, Germany):

    drupes & berries: 5 - 10 ml / hl (hl = 100 liters)
    pome: 10 - 15 ml / hl
    jerusalem artichoke: 20 - 50 ml / hl


  • Question 11

    rodrigo | spain, 28.02.2023 11:25:23

    the total alcohol was too high at around 7%ABV so the bacteria stopped working once they got close to 6.5% acidity?

    seems odd since generators say they can go to 12%). I have successfully made vinegar to 6% before but never tried higher.
    Reply

    No. Even for non-specialized vinegar bacteria (the "good" ones) is 7 %ABV not too high. BUT: It's also important to consider the so-called "total concentration". This is the sum of acidity (in %) and alcohol concentration (% ABV). If this value

    is too high, even a lower alcohol content may cause troubles. To be save, take care the total concentration is not higher than

    something about 10 to 12.

  • Question 20

    mario | italy, 27.02.2023 11:28:30

    I bought 1kg of dry roots on the link you gave me, for now I will try to make gentian-apple brandy, next year I will try to

    make pure root gentian brandy, I tried to ask here in Italy for the sale of roots fresh from those who make them, but they told me that for a large one they must be ordered first… I just wanted to ask you: do the dried roots I bought have to be finely chopped before they are added to the mash? or can I leave them as they are?
    Reply

    They are already chopped, so they're ready to use.

    I'm wondering if the Leonardo can distill both essential oils and spirits?

    Reply

    As extensively described in the online-shop, the type Leonardo is only for hydrosols and essential oils. If you want to produce, or rather distill, both, essential-oils/hydrosols and alcohol, the type Deluxe would be perfect.

  • Question 19

    Emerita | Venezuela , 15.10.2022 19:13:21

    Hello, I hope You are well. A question: I distilled oregano, and I obtained essential oil in several containers. I Left it in the containers for more that a month and as can be seed in the photography, there are many drops of the oil disperse in the bottle, Why is this happening? Thanks You very much for your attention.

    Reply

    The oil drops stick on the wall because of adhesive forces and surface tension effects. Just strongly twist the bottle along its
    vertical axis back and forth, as thoroughly described in our book.

    Having said that, in general, colored oil bubbles look much bigger than they are, if they do not flow up to the top after twisting. These bubbles are even too small to be soaked up by a syringe with attached hypodermic needle.


  • Question 10

    Wanderer Wondering | Portugal, 24.03.2022 20:30:20

    First time i attempted to make vinegar.


    I cut fresh oranges into 8 pieces and filled a 4litre jar 75%. Then added 3litre of water and 1 cup sugar.


    Stopped bubbling after 4 weeks. Removed fruit and strained most of it. Seems to have a mother.


    pH is 3.7 but earlier in the process while still bubbling is went down to 3.2.


    Not a strong vinegar taste. Leaves a bitter aftertaste.


    Can i correct this? What did i do wrong?


    Rob

    Thank you for your photo, it obviously shows, there is no mother-of-vinegar (MOV) at all. Since orange juice is very rich in trace vitamins, minerals, and sugar, the MOV will become considerable thick after fermenting for only about a week, i.e., between 0.5 and 1 cm (about 0.2 to 0.4 inches). Besides this, for the same reason the MOV will be quite stable (can only be torn up with both hands and a bit of force) and gelatinous like a jellyfish.


    To learn properly how a vinegar fermentation works, I would suggest to mix vodka, water, and orange juice, don't forget to add cultivated mother-of-vinegar, available at winery or vinegar producing suppliers. A detailed description of the recipe you'll find in the mentioned books (see https://www.making-vinegar.com/books/) or in our online seminar of course.
