With the Acetic Acid Analysis Set you can precisely determine the acetic acid content during fermentation or in the finished vinegar via an acid-base titration with sodium hydroxide solution and phenolphthalein. The set is ideal for anyone who wants to do more than estimate the acid content by taste and instead measure it cleanly.
The method is among the most accurate simple determination methods for acetic acid. It is particularly suitable for monitoring the fermentation progress, for testing finished vinegars and for preparing further analyses, for example for the Schmickl Alcohol Analysis Set.
Why an Acetic Acid Analysis Set makes sense
Vinegar can certainly be assessed by taste, but the actual acetic acid content cannot be reliably determined that way. If you want to know how sour a vinegar really is, you need a precise measurement method.
With the Acetic Acid Analysis Set, the acid content is determined via a titration. The acetic acid is neutralised with sodium hydroxide solution and the colour change is made visible with phenolphthalein. In this way you obtain a verifiable measurement value rather than a mere estimate.
Use during fermentation and on the finished vinegar
The set can be used both during the acetic fermentation and on the finished vinegar. During fermentation, the measurement helps monitor the progress of vinegar formation. On the finished product, it serves to verify the end result.
This is particularly practical when several batches are to be compared or when a vinegar is to be produced as consistently as possible. Particularly for fruit vinegar, beer vinegar, herb vinegar or other in-house batches, the measurement provides a reliable basis.
