What to do

Next steps

  1. 1

    Check the smell and surface layer

    If the darkening is only on the surface and the smell is clean with no hissing, it is more likely a cosmetic defect than a critical one.

  2. 2

    Evaluate texture and taste

    A bitter, burnt, or sharply sour note may indicate that the issue is not only the color, but also overheating or unwanted fermentation.

  3. 3

    Handle the next batch more gently

    Lower the temperature, reduce the time of vigorous boiling, and minimize the product’s contact with air after opening.
