Quick Answer
For off-grid yogurt storage, look for vacuum jars with a suitable vacuum seal and a capacity of at least 1 quart (1 liter). Mason jars with a vacuum sealer attachment or dedicated vacuum jars like the Fido or OXO Good Grips are good options.
Choosing the Right Vacuum Jars
When selecting vacuum jars for off-grid yogurt storage, consider the material, size, and vacuum sealing mechanism. Glass jars are ideal for storing yogurt, as they are non-reactive and easy to clean. A capacity of at least 1 quart (1 liter) is recommended to allow for proper fermentation and storage of the yogurt. Look for jars with a wide mouth for easy scooping and a smooth interior to prevent bacterial contamination.
Considering Vacuum Sealing Mechanisms
There are two main types of vacuum sealing mechanisms: manual and automatic. Manual vacuum jars require a separate vacuum pump or a siphon bottle to achieve a vacuum seal, while automatic vacuum jars have a built-in pump that creates the seal when the jar is closed. For off-grid yogurt storage, manual vacuum jars are a more reliable and cost-effective option. The Fido 1-quart (1-liter) vacuum jar is a popular choice, and its manual vacuum sealing mechanism is easy to use and maintain.
Tips for Vacuum Jar Maintenance
To ensure the longevity of your vacuum jars and maintain a proper seal, it’s essential to clean and dry the jars regularly. After each use, wash the jar with soap and warm water, and dry it thoroughly with a clean towel. Before sealing, make sure the jar is completely dry and free of any residue. Additionally, store the jars in a cool, dry place to prevent moisture buildup and maintain the vacuum seal.
