Quick Answer
Pressure canning at 6000 feet requires a higher altitude adjustment to ensure safe sterilization, typically adding 5-10 minutes to the recommended processing time.
Adjusting Pressure Canner for High Altitude
Pressure canners have altitude adjustments to account for lower air pressure at higher elevations. To can safely at 6000 feet, set the canner’s altitude adjustment to the recommended setting for 5000-6000 feet, which is typically 5-10 minutes above the standard processing time. Consult your canner’s user manual for specific instructions.
Pressure Canner Gauge Accuracy
To ensure accurate pressure readings at high altitude, use a pressure canner gauge with a temperature compensation feature. This feature accounts for the lower air pressure and provides a more accurate pressure reading. A temperature-compensated gauge can help prevent under-processing, which can lead to spoilage or even foodborne illness.
Processing Time Adjustments
When canning at high altitude, processing times may need to be longer to ensure safe sterilization. A general rule of thumb is to add 5-10 minutes to the standard processing time for every 1000 feet of elevation. For example, if a recipe calls for 30 minutes of processing at sea level, add 10-15 minutes at 6000 feet for a total of 40-45 minutes. Always consult your canner’s user manual and follow the recommended processing times.
