Quick Answer
Double processing of venison jars is recommended to ensure the meat is heated to a safe temperature, killing off any bacteria that may be present and preventing spoilage.
Safety First: Understanding Pressure Canning
When it comes to canning venison, safety should be the top priority. Double processing involves processing the jars twice, with a 10-15 minute interval in between. This allows for a second heating cycle, which is essential for reaching the required temperature of 240°F (115°C) to kill off any bacteria that may have survived the first cycle.
Choosing the Right Jar Size
When selecting jars for canning venison, it’s essential to choose the right size. A good rule of thumb is to use 1 pint (475ml) jars for pressure canning, as they provide adequate headspace and allow for even heat distribution. Smaller jars, such as 1/2 pint (235ml) or 4 oz (115ml), can be used, but they require more precise temperature control and may lead to uneven heating.
Processing Times and Shelf Life
The processing time for venison will depend on the altitude and the size of the jars. At sea level, processing times can range from 45-90 minutes, while at higher altitudes, the times may need to be adjusted. Once the jars have been processed and cooled, they can be stored in a cool, dark place for up to 12 months. It’s essential to check the seals regularly and use a clean, dry cloth to wipe off any excess moisture from the jars before storing them.
