I think I can get unpasteurized organic milk, come to think of it.

In Michigan you can only get it through the legal loophole of the "herd share". Basically, you don't have to pasteurize milk from your own cow for your own use and there's no law saying who has to care for the cows or do the milking. It's a big thing on the western side of the state, but there don't seem to be any dairy farms around here that offer herd shares. It doesn't help that it exists in a legal grey area -- you gotta know someone, y'know?

JB - Only UHT organic milk here that I can find. Maybe the stuff in glass bottles at Byerly's is only pasteurized, but I really don't want to spend $10/gallon on milk.

KP - There are risks with unpasteurized milk, listeria among them. I would find it difficult to trust someone's sanitation practices unless I knew them really well.

I was thinking that scalding would kill nasties in unpasteurized milk, but with less cooking of the proteins than you've noticed in UHT organic milk. But I wasnt very luck determining the temps that kill listeria.

I assume that the turnover is still low enough for organic milk that UHT processing is common in order to get an economical shelf life?

That's my guess. Trader Joe's organic milk doesn't say it's ultra pasteurized so maybe it will work. But I like their Greek style mango-apricot yogurt so much that I just bought a ton of that instead. Eh, maybe next time. I really hate going to TJ's though because it's always a zoo.
