why does milk sour in a thunderstorm?

Hiya brye, Same here for me I have heard of that before. Milk has to be kept in the Fridge all the time if you leave it out it could turn sour. Has something to do with "changes" outside. Say if you had bottles of milk on the Doorstep and there was a strong enough storm they could well be affected. But it seems that there is no real explanation given anywhere for it. People who live in the Countryside know more about this than most I think. Milk unopened in the Fridge should be perfectly safe however just in case loose a little milk down the sink before trying it and see if it forms those curdles on top. Honestly I don´t think it would though. I think it has to be a really strong Storm to affect milk like that. This comes from what I have been told ages ago and seeing other Peoples opinions on other web pages.

I never heard about that. But if the milk is not kept in the fridge but wasn't still opened, I think (just a theory) that the temperature and pressure causes some chemical reaction to the milk. I'm not sure okay, I just hypothesized that, lol. If there's a thunderstorm, I'll try to experiment.

It wont sour if you keep it refridgerated
