What To Do If Mold Forms On Your Aging Cheese?

Assessing the Situation

When mold forms on your aging cheese, it’s essential to determine if it’s a harmless type like white mold or a potentially toxic one like green or black mold. White mold, also known as Penicillium candidum, is often desirable in aged cheeses like brie and blue cheese, but if it’s accompanied by a strong, unpleasant odor or slimy texture, it’s best to err on the side of caution. Inspect your cheese carefully, and if you’re unsure, discard it.

Removing the Mold

If you’ve determined the mold is harmless, remove it by gently scraping off the affected area with a clean, dry knife. Be cautious not to scrape too deeply, as this can damage the cheese and create an entry point for bacteria. For harder cheeses like Parmesan or cheddar, you can use a cheese wire or a knife to carefully remove the mold, taking care not to scratch the surrounding cheese.

Preventing Future Contamination

To prevent further contamination and promote the growth of beneficial mold, apply a protective barrier to the exposed area. This can be done by brushing the cheese with a thin layer of melted wax, oil, or beeswax. Be sure to use a clean and sanitized utensil to apply the barrier, and avoid touching the cheese with your bare hands. By taking these steps, you can help ensure the continued safe aging of your cheese and promote the growth of desirable mold.
