@Devonviolet had digestive issues drinking it pasteurized but can drink it with no problem when raw.
I had allergy testing 9 years ago, that showed sensitivity to casein, which is the protein in milk. I've never had a problem with milk. But then, I never drank a lot of it.
2-1/2 years ago I found a local dairy, that sold raw cow's milk, and I started drinking their milk, again without a problem.
Then I got our 2 LaMancha does last Winter & started milking last Spring when they kidded. After talking to some goat people, I decided to pasteurize our milk.
Gradually, I began to notice increasing amounts of phlegm in the back of my throat (which is my clue that I am reacting to a food.) So, I thought I was reacting to the casein in the milk, and I would have to give up milking my goats.
But, knowing that heating the milk destroyed the enzymes that helps the body digest the protein (casein) in the milk, I thought maybe pasteurizing the milk was causing my problem. So, before selling my girls, though, I decided to stop pasteurizing the milk and see if that made a difference. It took a while, before I noticed a decrease in the phlegm, but now it is totally gone!
I do make mozzarella cheese, which only requires temps to 105°F., and that doesn't cause a problem. There are cheeses that require high temps (something like 195°F) and I am staying away from those cheeses, at least for now.
I use the same process that
@Southern by choice mentioned (except for the pasteurization, of course), and I don't put the milk in the freezer.
I filter it (with a slightly different filter), and I use the newer, white plastic Ball canning jar Lids (which don't fully seal), with a metal canning lid (the kind that comes with a 2 part canning lid/ring, for canning. I screw on the plastic lid tightly and put it in the fridge right away. When the milk cools, it causes a seal to form.
The metal lid seals tightly, and our milk always has a sweet, fresh taste that lasts 10 days.
The filter (which looks very similar to a canning funnel), is slightly different than SBC's. It uses a stainless steel ring to hold a cloth fiber filter in place
