Wine and Mildew: A Guide to Cleaning and Maintaining Your Wine Collection

Why is Mildew Such a Problem in Wine?

Mildew, also known as botrytis cinerea, is a type of fungus that can grow on the surface of wine bottles and corks. It's a common issue in wine storage due to high humidity, poor ventilation, or contamination from other sources.

The problem with mildew is that it can cause significant damage to your wine collection. Not only does it ruin the appearance of the bottle, but it also poses a risk to the quality and safety of the wine itself.

How to Prevent Mildew from Growing in Your Wine Collection

Preventing mildew is much easier than trying to remove it once it's grown. To start, make sure you're storing your wine collection in a cool, dry place with good airflow.

Avoid stacking bottles on top of each other or near any sources of moisture, as this can create an ideal environment for mildew growth.

Removing Mildew from Your Wine Bottles

If you do find mildew on your wine bottle, don't panic! Removing it is possible, but it requires some care to avoid damaging the bottle or contaminating the wine.

Start by gently wiping away any loose mold with a soft cloth. Then, mix equal parts water and white vinegar in a bowl and dip a clean cloth into the solution. Gently wipe down the affected area until the mildew is gone.
