What Mould on Wine Bottles Means
Liebherr lists mold on bottles in the Malfunction chapter and then declines to treat it as a problem. The explanation given is that a little mold can form depending on the adhesive used for the label, exactly as it can in any other form of wine storage, and the remedy offered is to remove residual adhesive.
Common Causes of Mould on Wine Bottles
- Label adhesive providing a growth medium at wine-storage humidity
- Residual glue left on shelves from previously stored bottles
🔧 One Safe Check You Can Try
Wipe residual glue off the bottles and the shelf below them. Since Liebherr wine cabinets are designed to run at a humidity that suits corks, the same conditions will occasionally suit a label adhesive too — which is why the manual treats this as housekeeping rather than as a breakdown.
⚠ Why You Shouldn't Go Further Than That
- Mold that returns quickly across a whole shelf, rather than appearing on individual labels, suggests standing water or a drainage problem rather than adhesive, and that is worth looking at properly.
- Confusing this with a cabinet problem leads people to dry the interior out, which is the opposite of what a cork needs.
