The 10 Best Pressure Canner For Home Canning Reviewed

The best type of pressure cooker for canning is a dedicated pressure canner. These are designed specifically for the high temperatures and pressures needed to safely preserve low-acid foods. When selecting a pressure canner, consider the following features:

1. Capacity: Look for a canner that can hold at least four quart-sized jars. Common sizes include 16-quart, 23-quart, and larger.
2. Pressure Control: Ensure it has a dial gauge or a weighted gauge to accurately regulate and monitor pressure.
3. Material: Choose heavy-duty materials like aluminum or stainless steel for durability and even heat distribution.
4. Safety Features: Ensure it has built-in safety features such as pressure release valves and secure locking mechanisms.

How Much PSI Do I Need for Pressure Canning?

The psi needed for pressure canning depends on your altitude:

• 0-1,000 feet above sea level: Use 10 psi.
• Above 1,000 feet: Use 15 psi.

These pressures are necessary to reach the high temperatures required to kill harmful bacteria and spores, ensuring food safety.

What's the Difference Between a Pressure Cooker and a Pressure Canner?

The main differences between a pressure cooker and a pressure canner are:

1. Size: Pressure canners are larger to accommodate multiple canning jars, whereas pressure cookers are smaller and designed for cooking meals.
2. Pressure Control: Pressure canners have precise gauges (dial or weighted) to monitor and control pressure accurately, which is essential for safe canning. Regular pressure cookers may not have such precise controls.
3. Safety Standards: Pressure canners are built to specific safety standards set by the USDA for home canning, ensuring they can safely reach and maintain the necessary pressure for extended periods.
4. Purpose: Pressure cookers are designed for quick cooking of meals, while pressure canners are specifically designed for the preservation of low-acid foods.

What Kind of Pressure Canner Do I Need?

When choosing a pressure canner, consider the following:

1. Capacity: Determine how much food you plan to can. A 16-quart canner is good for small batches, while a 23-quart or larger canner is ideal for larger batches.
2. Material: Opt for durable materials like aluminum or stainless steel for even heat distribution and long-term use.
3. Pressure Gauge: Decide between a dial gauge and a weighted gauge. Dial gauges require calibration checks, while weighted gauges do not.
4. Stovetop Compatibility: Ensure the canner is compatible with your stovetop, especially if you have a glass or induction cooktop.

What Happens If I Can at Too High a Pressure?

Canning at too high a pressure can lead to several issues:

1. Overcooked Food: The food inside the jars can become overcooked, resulting in poor texture and flavor.
2. Jar Breakage: Excessive pressure can cause jars to break or lids to fail, leading to potential contamination.
3. Nutrient Loss: Higher temperatures can degrade the nutritional quality of the food.
4. Safety Concerns: While higher pressure can kill bacteria, it can also cause uneven processing if the pressure fluctuates too much.

Always follow recommended pressure guidelines for safe and effective canning.
