Do cold temperatures cause contamination?
    #27300849 - 05/08/21 09:41 PM (3 years, 8 months ago)

I was wondering if this theory is valid?

1) Cold temperatures cause outside the jars to be cooler, which causes condensation inside the jars.

2) Condensation in the jars is attractive to bacteria (provides an opportunistic environment even after proper sterilization).  Jars then start to have a sweaty appearance and moisture drips down from the tops of the jars and touches the top of the grain level.  See picture:



3) Bacteria multiply more quickly than normal causing even master jars (i.e. wedge inoculated) to contaminate.

4) G-G processes cause downstream contamination.

I think this would be absorbed over time,
maybe it`s a problem if it`s pooling at the bottom.
I always have some condensation, cause it`s some degrees up in the jar,
never an issue for me.

I would have to agree with you to some degree. However if you get your grain dry enough before PC'ing then there shouldn't be enough moisture in the jar to create enough liquid condensation to result in bacteria.

Or i guess you cud keep your jars in a warm environment with less temp swingz.

Definitely- I go to extra effort to try and keep the grains dry, even adding extra dry grain to the prepped grain to absorb extra moisture, but I may need more 🤔
