PF tek jar lids -- loose or tight?

#661005 - 06/03/02 04:21 PM (21 years, 4 months ago)

I'm going to be using the pf tek with 1/2 pint wide mouth Ball jars. I was assuming that the lids should be screwed down tight prior to sterlization and kept that way, but then I read some posts/faqs about controlling the moisture in the jars during colonization and thought maybe they should not be tightened, but rather loose. I guess that would make sense since the tek says to put the rubber gasket side of the lids up instead of down on the jar lip which would prevent a good seal.

So which is it, tight or loose?

If you decide not to tighten down the lids remember to top the jars off with the plain dry vermiculite to ward off contams.

Hey, thanks for the reply. I've since found and have been reading the posts about using filter discs. That seems like a great idea. I wonder if coffee filters would work?
