PCing at 7000ft
    #29724894 -

Hello,
I live at quite a high elevation (around 7000ft) and I’m curious how I should go about PCing grain. I heard something about increasing PSI but I’m not sure how to go about doing this. I’m also aware I should increase cooking times but everyone’s opinion on by how much is different. Any advice?

I’m also still trying to decide which PC I should get for this. I’m looking at the Tfal 22qt because it’s much cheaper but also the presto 23qt.

You can either increase PSI or PC time.
Probably easier to increase time.
Increase the cooking time by 5% for every 1,000 feet above 2,000 feet elevation when using a pressure cooker.
At 7,000 feet, you should increase the cooking time by 25% compared to sea level.

I can’t help but feel like this image is a bit inaccurate because for some reason the pressure at 8000ft is higher than 7000, and 7000=9000 on this

You can get a used 16 qt on fleabay or even C list, sometimes I see low usage 23qt prestos for 60 bucks, if I wanted to drive to Grass Valley or farther. They all look new or low usage compared to mine, but I want an electric one for the garage one of these days.  I'll keep my eyes open, maybe I find my new workhorse.

Nice chart Veggie, I'll let you know when I have to PC at Donner Summit.  :laugh:

If you have a gauge along with a rocker weight, you add some weight. No, it won't explode. If you don't have a gauge, don't add weight (you really want to know what your pressure is), extend your time 25% (or more, can't be overkill with sterilization) like Veggie said.
