I shake the cream in! I can't stand skim milk, so I don't ever skim our drinking milk. But the cream can be used for whipping, for coffee, for cooking/baking with, and for butter. Yum!
With the leftover skim you could make a quick ricotta using citric acid.
Cow milk is yellowish because cows convert Vit A into beta-carotene. But goats (and Ayrshire cattle) don't - the milk is always white, no matter what they are fed. The color varies by breed - grassfed Holstein milk is usually whiter than non-grassfed Jersey milk.
Good raw milk should last 10 days. I usually tell people that you can count on 7 days, usually 10, and if you store an unopened bottle properly, it might last 2 or more weeks. I've found it takes 2-3 weeks for a bottle to sour, but after a week the taste starts to fade.
I shake the cream in. Don't throw it out! Even if you didn't want to drink it, you can use it make excellent butter! I noticed a bit of a yellow color in some I just got, the lady said one of her cows had given birth recently and the milk was exceptionally rich in cream right now. mmmm good.
I usually drink it cultured, as clabber, yogurt, buttermilk, or kefir.
I've had the raw milk last two weeks in the fridge and still taste good. But I actually like it soured so I might just not notice any off taste. I keep my fridge just above freezing.
I haven't tried making butter yet, but the easiest ways I've seen online to do it are to let the cream separate to the top of the milk, then siphon that off (or use a cream separator, which is basically a large jar with a spout at the bottom, so you can pour off the milk portion until all that is left is cream). Then put the cream into a blender or food processor and whip it until the butter and buttermilk are formed. Then you put that into a wooden bowl and press it with a spatula to work out the buttermilk. Then you can wash the butter with water (makes it keep longer) and that's about it. You can culture/ferment the cream first - that's the way I'm planning to do it when I try it.
Maybe I'm too gentle with my raw milk... somehow I picked up the idea that I wasn't supposed to shake it, just gentle agitation to blend the cream in. Some delicate little beneficial thing in the milk can't handle a nice shake? Would love to know if anyone has a real fact to share on this.
Meanwhile, my answer is - gentle agitation and then cupfuls a day for me and my son.
I know you arent supposed to shake breastmilk because it can destroy something? in it, and I have always tried to be careful with my raw milk too as well:)
