How to Keep Tomatoes Fresh for 6 Months: Grandma’s Tried and True Method Using Glass Containers (Page 2 ) | June 28, 2025

Sterilization Process: To sterilize, wash glass containers and lids with hot, soapy water. Then boil them in a large saucepan for about 10 minutes. Carefully remove the containers and lids and allow them to dry completely.

Storing Tomatoes: Layering Technique: Start by placing a layer of tomatoes in the container. Make sure they are not too tightly packed; there should be a little space between each tomato to prevent bruising and allow air circulation.

Sealing and Storage: Once the container is full, close it tightly with the lid. Store containers in a cool, dark place, such as a basement or pantry. Avoid areas with large temperature fluctuations.

Tips for long-term freshness: Regular checks: It is essential to check your tomatoes regularly. If you notice any spoiled tomatoes, remove them immediately to prevent the damage from spreading to others.

Ideal storage conditions: Maintain a constant, cool temperature. Extreme temperatures, both hot and cold, can harm tomatoes.

The science behind the method: This method works because sealed glass containers create a barrier against oxygen, moisture, and light—three factors that contribute to tomato spoilage. By limiting these factors, it’s possible to significantly extend the shelf life of tomatoes.
