Starter wort Canning help

[cornhole]

This is an edit of my previous post.

I'm an idiot. Just re-read Bugeater's remarks and it makes sense now.

Starter wort wouldn't have the ph (i.e. no hops) to prevent repro. of spores because hop acid in a starter doesn't help the propagation of yeasts.

I got an old pressure cooker and haven't used it yet. The old type aluminum one without a gasket (kind of like a tri-clover sealing, but without gasket).

I guess I'm a little afraid of using it........

Anyway, what about week-old wort? Should I worry about botulism in that? I have some wort I refrigerated about a year ago. Methinks I should toss that out...

Final question: can the white labs vials be put in a pressure cooker?

Why not just freeze starter wort in quart freezer bags?

You can freeze wort in bags, I did just that for a long time and might even still have a couple of "bricks" of wort under the hops. Bad part is you still have to boil and chill and that takes time compared to opening a jar and dumping it in.

botulism = scary shit huh?

As long as I am not trying to can unfermented wort, or anything like that... botulism isn't really a threat in the avg. brew process... correct?

Never heard much about this, so I did a touch of research just now, and It sounds like it can produce somes pretty narsty neurotoxins. Not something I would F with.

So is there any consensus about this?

Will freezing wort prevent botulism?

I tried the pressure cooker and was SCARED of it. I read instructions and let steam out for 10 minutes before closing the blowoff and saw the pressure go up. And up. It SEEMED to pffft pffft every few seconds from the regulator (I could hear it but couldn't confirm where it was coming from) but it hit 240, then 253. The start of the danger range seemed to be at 270. So at about 260 I cracked the blowoff but made it maintain that for 10 minutes.

I didn't try it with wort yet. Trying to figure out if it's even worth getting the bell jars.

By the way, White Labs vials turn opaque white after sterilization. Just saying....

You won't get activity from botulism in frozen wort, but it is not sanitary. It will still need to be boiled.

When you hit 250 on the pressure cooker, you're going to get pfft'ing. It should be rhythmic and constant, but low key.

When you come up to 15 psi, you should back way off on the heat, just enough to maintain it right there. As long as you do that, a pressure cooker is safe as kittens.

As long as you do that, a pressure cooker is safe as kittens.

As safe as 15lb., 60 year old aluminum kittens...


Thanks for the answer!!!
