I had the impression that US milk has no taste but always thought it's just in my mind. But when I was in Colombia I met a guy from Switzerland who studied in Canada and said:"Oh wow, the milk here really tastes good like in Europe. Not like in Canada." So the milk in Europe and North America must indeed taste different. It is not just in my head.
It's grass fed; if you buy it in the farmer's market, it's a couple of days fresh; and they care about their cows. I bought a bottle once, which didn't taste as good as usual, and when I told the guy at the market (he actually raises and cares for the cows), he took notes to figure out which cow was unhappy/unwell.
Not affiliated, was just a satisfied customer until I moved out of NYC (and now have no good milk available :( )
In Northern California, Saint Benoit [2] markets Jersey cow milk and yogurt. The flavor of their milk is incomparable to all others I've ever tried stateside.
