UHT, on the other hand, kills everything.

Also asked, why does some milk have longer shelf life?

Does milk spoil faster in plastic containers?

Many health experts say organic milk is well worth the extra money because it contains no growth hormones and no antibiotics, and because the production process is more sustainable and humane than some other dairy farming practices.

Why does Horizon milk taste different?

The biggest taste difference is due to how it's pasteurized. Organic milk moves off grocery store shelves more slowly, so processors use a process called UHT pasteurization to extend the shelf life, but this also impacts the flavor. Some like it, some don't.

Milk is made shelf-stable (refrigeration not required for storage) by pasteurizing it at a higher temperature. Which is called ultra-high temperature pasteurization, or UHT pasteurization. Traditional milk is heated up to at least 161 degrees for 15 seconds to kill harmful bacteria in the milk.

Should you store milk in the refrigerator door?
