Quick Answer
For making yogurt off-grid, the best vacuum jar brands are MasonCash, Kilner, and Weck, all of which offer a tight seal and are suitable for use in a cold room or with a yogurt maker.
Choosing the Right Vacuum Jar for Yogurt Making
When selecting a vacuum jar for yogurt making, it’s essential to consider the material, size, and seal quality. MasonCash jars, for example, are made from durable glass and come in various sizes, including 250ml and 500ml options. These jars are ideal for small-batch yogurt making and can be used with a yogurt maker or in a cold room.
Tips for Using Vacuum Jars with Yogurt
To make yogurt in a vacuum jar, start by heating your milk to the desired temperature (usually around 180°F to 185°F). Let it cool to around 110°F to 120°F, then add your yogurt starter culture and incubate in a yogurt maker or a cold room (around 100°F to 110°F) for 6 to 8 hours. Once set, store the yogurt in the refrigerator and use a vacuum jar to seal and preserve it.
Maintaining a Vacuum Seal for Long-Term Storage
To ensure a tight seal and prevent contamination, it’s crucial to maintain the vacuum seal on your jar. This can be done by placing the jar in a pot of hot water (around 180°F to 190°F) for 10 to 15 minutes, which will create a vacuum seal. This technique is particularly useful for storing yogurt for long periods or for transporting it off-grid.
