How to Keep Used Coffee Grounds from Molding
Coffee grounds, when left overly wet, are susceptible to mold growth. This can be especially concerning for coffee drinkers who like to use a French press or pour-over brewing method because a majority of the used grounds remain in the coffee-maker. To prevent mold growth, it’s important to keep used coffee grounds dry. Here are some easy tips to help you keep your coffee fresh and mold-free:
Choose an Appropriate Container
- Storing your grounds in an airtight container is an incredibly important first step.
- The container should be made of a material like metal or ceramic that resists moisture.
- Typically, metal containers are the best choice because they provide the most air-tight storage.
Proper Storage Practices
- Always ensure your container is completely dry, both inside and outside, before adding new coffee grounds.
- Keep your container in a cool, dry and dark place. Optimal temperature should be room temperature or lower.
- Pour away any extra water remaining in your coffee-maker between uses.
Using Fresh Grounds
- Try to use up your grounds within a week or two of purchasing or grinding them.
- Purchase the freshest beans you can, ideally from a local roaster.
- Be sure to only grind the beans you’re going to use within the hour.
By following these easy tips and tricks, you can protect your coffee grounds from mold growth and maintain the optimal flavor of each brew. With the right preparation and proper storage, you can brew the freshest and most delicious cup of coffee every day.
