Good Options Here!
Over at the Localvore.org site, someone mentioned that they liked the quasi-organic milk owned by Dean Food's called Horizon. I'm not a fan at all of Horizon. See how they rank against other organic milk companies here. Not only are there much better dairy companies, but there are great companies local to us in the Chicago area. Note, while I'm still too nervous to try raw milk, I could surely find many sources for raw milk in Wisconsin. Me, I'm happy with the non-raw but local sources available to me. Mostly, I use the ones described below.
Our default milk is Farmers' All Natural Creamery from Amish and Mennonite farmers in Iowa. It's organic, low temperature (VAT) pasteurized and non-homogenized, about all you want in non-raw milk. More importantly, it is widely available at Whole Foods and other places in the Chicago area. If you don't shake well, you will use all the cream (fat) in the first pour. Sweet.
Three other dairies of the same (or even better) quality are Crystal Ball Farms from Wisconsin, Trader's Point Creamery from Indiana and Oak Grove Organics from Illinois. The last sells a cream that is, well to be trite, to die for. Crystal Ball and Trader's Creamery can at times be found at Whole Foods (Trader's Creamery's yogurt is there). Both sell in small bottles. I like that as I can buy fresher milk. I'm a believer that newness matters with dairy. Fox and Obel is another sources for these milks and creams.
Organic Valley is based out of Wisconsin. It's a cooperative. In general, they have great practices (see link above). It's likely that the products sold around here would come from local farms, but there's no guarantee as they sell nationally/they use farms from around the US. What I especially don't like is that Organic Valley's milks and creams are all ultra-pasteurized. I will buy other stuff from them like cottage cheese and cheddar cheese.
For reasons having nothing to do with taste, farming practices, hormones, localness, etc., we do not buy Oberweiss stuff.
