How long before jars can be taken out of PC?
    #1964439 - 09/30/03 12:38 AM (13 years, 9 months ago)

"Jars need to cool before inoculation because spores are killed by excessive heat (such as the temperature inside a PF-tek style jar after being boiled for 45 minutes to an hour). So, you need to let the jars cool on their own, preferably for at least 6 hours, and hopefully overnight. It is recommended to cool jars directly in the pot in which you boiled them, since this will reduce the chance of airborne contaminants landing on the lids of your jars (contaminants can't land on jars that are kept cooling in a covered pot). A jar cool to the touch may still be too hot inside for spore life, so do not judge the internal temperature of the jars by touching the glass. And do not open the jars for obvious reasons. FINALLY, DO NOT COOL JARS UNDER COLD WATER OR IN THE REFRIGERATOR. Cold water/air hot glass = cracked glass and unusable substrate. Trust us on this one, the glass WILL break if made too cool too quickly. A mantra in this hobby - "patience, young jedi." "


It says above that its best to let them cool in the PC, as to not allow contams into the cooling jars, but my question is:

If all the jars are covered in foil (which i'm assuming will fix that problem about having to cool them in the pot) how long after cooking can i safely remove the jars, to allow them to cool on a shelf or something. My PC is only 6 quarts, which means I can't do them all at once, and it would be very inconvenient to have to wait at least 6 hours before i can start PCing the next batch. 1 hour ok? 2 hours? should the outside of the pot just be somewhat cool to the touch? thanks for the help.

if you remove them then place them into a rubbermaid that has been sprayed down with lysol or wiped down with bleach, you should be able to take them out directly after the PC has lost all its pressure, just put the lid on rubbermaid once the jars are in and you shouldnt have any problems..

p.s. let the lysol disappate before putting the jars in. my FOAF takes his out right after the PC has reached equal pressure and puts them on a sterilized kitchen counter top...but that is NOT advisable.

does it matter if your jars have tyvek on them, and as soon as its opened lids are tightend on jars and left on counter to cool, how can contams get in? thats what the tyveks for right, seems safe

if you have tyvek i definatly wouldnt worry about it, you MIGHT run into some contam problems, but its negligable(sp?)

after one hour of pcing, this dolphin I know took it off the burner and dumped cold water all over the PC and it was back to normal pressure in like 30 seconds. he took them out with an oven mitt and put it on a rack to cool. right now its starting to fruit, 6 jars, no contam problems.
