Okay, I got it. When the female goats are left to roam around along with the males, it creates a hormone secretion which also gets into the milk and this is what causes the goat-y flavor.
Nothing like a horny nannie to ruin your milk. So, it has nothing to do with what they eat or how old the milk is, unless it's 4 months old or something, but all-natural raw would be fine and quite tasty if the females are separated from the males while pregnant and giving milk.
Another fact. If you are using raw milk regardless of cow or goat, once it sours, it's still perfectly fine to drink. The pasteurization and homogenization isn't in there, so it's totally safe to drink. Those two '
izations' ruin the enzymes and bacteria needed to keep the milk safe. Besides you can make yogurt out of it, bake all kinds of stuff with it or just make butter if you have the time.
Instead of thinking about convenience and how the government has interfered with our eating, just think about how our ancestors did it all.... and without chemicals, refrigeration or grocery store chains.
