What is needed?
| Ingredient | Recommendation |
| Vinegar mother | 100 ml active vinegar mother (Item No. 135536; optionally Item No. 135539) |
| Base wine | Dry, suitable wine, preferably unsulphited |
| Vessel | Clean, wide-mouthed, and not filled to the brim (Item No. 62331) |
| Cover | Clean, breathable cloth + fastener (Item No. 8395) |
| Optional | pH/acidity measurement and alcohol measurement (Item No. 135136) |
The 5 most important rules
- Use unsulphured wine.
- Ensure plenty of oxygen - do not seal the container airtight.
- Place in a warm, undisturbed spot away from direct sunlight.
- Work cleanly and keep fruit flies away.
- Give the mother of vinegar time and monitor the development of acidity.
Step-by-step instructions
- Prepare the vessel
Clean the vessel thoroughly and rinse well. A wide vessel is ideal because the large surface area improves oxygen supply. - Pour in the wine
Pour in dry wine - ideally unsulphured. Do not fill to the brim; leave sufficient headspace above the liquid. - Add the vinegar mother
Carefully add 100 ml of vinegar mother to the wine. Introduce the culture gently and avoid vigorous stirring. - Cover with a breathable material
Cover the vessel with a clean cloth and secure it. Do not seal airtight - acetic acid bacteria require oxygen. - Choose a location
Place in a warm, quiet spot protected from direct sunlight. Avoid significant temperature fluctuations. - Monitor development
Over time, a vinegar aroma will develop, and a new vinegar mother often forms on the surface. The process depends on temperature, alcohol content, oxygen levels, and culture activity. - Assess readiness
Do not decide based solely on a fixed number of days. Check acidity development, aroma, and taste; measuring acidity is useful for consistent results. - Draw off and filter
Carefully remove the vinegar mother, allow the vinegar to settle, and separate the clear liquid from the sediment. Filter if necessary. - Bottle
Pour into clean, suitable bottles. Save the vinegar mother (or active culture) for the next batch.
Suitable base wines
The process is suitable for, among others:
| Base wine | Potential vinegar | Character |
| Grape wine | Wine vinegar | Classic; fruity or robust, depending on the wine |
| Apple wine | Apple vinegar
| Fruity, fresh |
| Pear wine | Pear vinegar | Mild and fruity |
| Berry wine | Beerenessigvinegar | Intensely aromatic |
Example: 5 liters of apple cider vinegar
Mixture: 5 liters of dry, unsulphured apple cider + 100 ml of vinegar mother.
- Prepare a clean, wide-mouthed vessel.
- Pour in 5 liters of apple cider.
- Carefully add 100 ml of vinegar mother.
- Cover with a clean cloth.
- Place in a warm spot away from direct sunlight.
- Check regularly and monitor acidity development.
- Remove the vinegar mother once the desired acidity is reached.
- Allow the vinegar to settle and filter if necessary.
- Bottle in clean containers.
- Save the vinegar mother for the next batch.
Avoiding Problems
| Problem | Possible cause / measure |
|
No or very slow vinegar formation |
Too cold, culture not very active, or unsuitable base wine. Check temperature and culture.
|
| Fruit flies | Cover the vessel with a clean, fine-meshed cloth. |
| Strong taste of alcohol remains | Conversion has not yet progressed far enough; continue monitoring. |
| Mold / clearly spoiled odor | Do not simply skim off and continue using. Critically examine the batch and discard if in doubt. |
NOTE: The vinegar mother is an active culture. It requires oxygen, warmth, and time. A clean, unsulphured base wine and effective protection against fruit flies are the most important prerequisites for a successful batch.
Notice:
This guide describes the traditional home production of vinegar using a ready-made vinegar mother. Product-specific dosage and usage instructions provided by the respective manufacturer take precedence. The batch should not be consumed if there are signs of unusual mold, a putrid odor, or other clear indications that the process has gone wrong.
