Hi Rose,
Here is a link to the write up on Cloverleaf Creamery - they are organic, grass-fed and use a low-heat pasturization process - I think that their milk is the best I have ever tasted. You can buy through Idaho's Bounty or thru the Boise Coop.
http://www.idahosbounty.org/shop/producers/livvy.phpThey also do ice cream (though not organic due to the flavorings, etc). Last year, Bill Stoltzfus (the owner) told me that they were getting into making butter and hope to make cheese in the future as well.
Thanks for posting here on BSLC!
