Double stacking pint jars

My canning book says that I can double stack pint jars in my pressure canner. Do I need to have
a rack or something between the jars or can I simply place the jars on top of one another?


Yes you do need to have a rack between your jars. You can purchase another rack just like the one that came with your canner or use some other type of rack.

How lucky you are that your canner will fit two layers!

These pages have ideas for other things to use for racks. Maybe they will give you ideas of what you may already have.

canning meat will this be ok????
by: fjaco2

recently I lost my 10# weight for my canner in a move so when cannng meat, and out town had none to buy!

I used the 15# one & kept the pressure between 10-13 # pressure (even though the weight did not vibrate/rock like it normally does at 15# the pressure was maintained for the full time for pints 75 mins

Should all of these jars be good?

Sharon's thoughts.....

Yes as long as you know the gauge is correct and that 10 pounds is your correct pressure I'd be ok with it.

Do i need to add more water in double stacking pint jars?

No you use the same amount as if you had one layer. The reason is that the pressure build up is what processes the food and jars. The amount of water is the same.

The purpose of the steam relief is so the steam circulates and no cold spots develop. It would be better to just process at 15 psi.
