Milk most definitely has different tastes depending on where the cows are from. Here in Arizona, we get milk from either California, Utah, or (believe it or not) Arizona. When we visit Wisconsin, there is a definitively different taste and texture (and I drink skim!). Here, skim milk is almost literally water, although I like it. In Wisconsin, the skim is slightly sweeter and thicker/creamier. When we were in Alaska, I failed to look at the carton to see where the milk was from (the little one half pint cartons). But it was kind of sweet. The chocolate milk was weird, almost as if they just put pure unsweetened cocoa in it and no sugar. So it was brown milk with the raw cocoa bean flavor.
