I tried organic milk once when it was at a promotion price and that stuff IS noticably better than regular milk.. I'm a big milk drinker, so I can see why he likes it better.. Unfortunately, we can't afford organic, so any milk is good for me.
Organic milk is rich and creamy. I haven't had milk since I was a kid, but I buy organic occasionally and will have a small glass a day. The expiration is like 3 or so weeks. It is nice to give my bones some calcium which I haven't my whole life. You may decide milk isn't so bad if you taste it.
