Autoclaving rye grain trouble!
    #4551725 - 08/18/05 03:32 PM (12 years, 4 days ago)

I soak 24 hours, then rinsed and drain. Load jar to 2/3, close with tyvek and polywool. I then pressure cook all the jar at 15 psi for 1 hour. Here what's happening : (not my picture, but it's almost the same thing)

This happen to 6 jar on 19! Only 13 is ok.. What the hell is happening ? Too much moist ? Please help.. Thanks

Do a simmer next time along with the soak. The simmer will help germinate the endospores and allow them to be killed more easily by PC'ing. Also, I usually PC for about 90 mins and never less than 70 mins when I am PC'ing whole grains. You also want to try to let the jars cool completely inside of the PC. The jars sometimes create a vacuum effect when they come out of the PC hot and this can suck in contams. Better luck next time dude.  :thumbup:
