Pressure cooking problems
#21964633 - 07/19/15 11:56 AM (8 years, 6 months ago) |

I recently started using a pressure cooker after moving up to grains. Pictured here is my first batch of PF jars from the PC as well as my first batch of grain jars which are 6 days old.
PF jars and Grain

For some reason, the PF jars look really bad, and look like the moisture content inside got screwed up somehow. On some of the jars, you can visibly see that the BRF/Verm layer got compressed and that because of that some of the dry verm layer leaked into the bottom layer. ALso, some of the BRF/Verm layers are visibly soaked. Because of this, im going to just go back to boiling/steaming the jars in a pot, because I haven't had a jar fail me that way yet. too early to tell if they contam, but im guessing a few of them will because of the messed up moisture content. Anyone know what could cause this?
As far as the grain jars, Im starting to think they are a lost cause, 6 days and no visible signs of growth. I know I inoculated them with enough spores(.25-.5mL in each jar) so I figured id see growth by now. Any ideas?
When I Pressure Cook, I make sure I put enough water, before I put the lid on the water is almost boiling and then I let steam come out of the vent for about 5-10 minutes before putting the weight on, at 15psi, I start the timer. If anything in that process is wrong please let me know, because I am confused as to why my PF jars came out the way they did as well as my grain jars not colonizing.
thanks

You gotta start using the search function and not just creating a new thread every time you have a question. 6 days with no growth is common if not expected. Germination takes time, even potentially 2 weeks.

I did. I could find nothing on my specific PF jar problem and no reliable or definitive information on grain germination or colonization

Did you cover the jars with aluminum foil? If not, that could be your problem. Also, maybe you have the water level too high in the pc and thus it boils up over or nearly over the sides of those short jars?

Keep the pf jars off the bottom of the PC. I always place the pf jars on top of the quart jars to be on the safe side. I can fit 7 quart jars with about 6 half pint wide mouth jars on top in a 23 qt presto canner.

Yes I covered them with foil and also elevated with the rack and two rows of the jar lids. Maybe the water was too high but I put it at the lowest allowed lvl in the pc.
Also, for your grains, how long did it take to see signs of colonization?

Just be patient, it can take up to 3 weeks before you see any signs of colonization. As long as there is no contamination in the the grain jars you should be fine for now.

Quickest signs of growth for grains for me...3 days...Slowest...almost 3 weeks...I know it's hard because you are excited (lord knows I was)...but patience will serve you well in this hobby

I would try grain to grain transfers if I was you as well.

I think the PF jars I made are toast. im looking at them, and most of the dry verm barrier has fallen and mixed with the lower level leaving chunks where there is none to filter the air. Im thinking about just dumping them out before they contam. What do you guys think, should I wait it out?

that's what im saying, the PF jars are probably fucked, the grains im thinking might be ok though. they looked fine when they came out of the PC. ill know in a couple days if they are done or not.
by the way thanks for the help man you are the best!

I can't tell by the pf jar pics. The grains don't look hydrated enough. Have you started any agar yet?

I am so confused, I soaked those grains for 24hrs, then boiled for 10 minutes, dried for about 20 while steam came out then PC'd them.
Grains are harder than I thought, would you toss them?
I am starting it tomorrow, I have everything laid out, just didn't have time today.

You need to simmer them for about 40 min then boil for about 10. I suggest tossing them and getting all your ducks in a row so you don't get too frustrated and give up. Do agar tomorrow and in a week transfer the myc to more agar. What's your plan for the agar?

never thought about simmering them, as RR's videos do not suggest it. Unfortunately I started another batch of grains today and although they look a little more hydrated than the other batch after about a day about half of the grains inside look dry.
im at the point where im frustrated and wasting money, if the other jars don't colonize within 4 more days I think ill toss em and have to start over.
As far as the agar, I was going to start with the pre mixed PDA I have and innoc it with MS, I have a few MS syringes with about 2-3 CC of liquid left in them and I figured they'd be good to use
I was going to use that agar to innoc the next batch of grain jars\
these were the grains right after PCing:

In my experience, PF style jars do not play well with my pressure cooker. It always seems to like... cook, the rice flour. It just ends up as a somewhat solidified puck. The flour/vermiculite shrinks, the top later rains down the sides, and they look paler in color than anticipated.
This happened when id do PF jars with my grain jars in the same run. I think it may be that the 90 minutes I spend at 15PSI may be too much for the rice flour. I havent bothered to go back and try a shorter time frame with them, but its worth a shot.
For the record I dont let the pressure off too fast or anything, so its not rapid steam escape causing the issue. Its just a strange quirk I noticed the few times I experimented with PF jars in my grain runs. I should note that I use my PF jars for experimenting with edibles and are usually supplemented with wood and/or manure, but that never caused issues in the steam bath method.
