Goat milk tastes wonderful no matter how you chill it. I raised a large milk goat once. I have heard that if they keep the male in with the does it can affect the milk a bit, but not to that extent I wouldn't think. Also what a goat eats could have an impact and there is also the issue of some kind of contamination which I would be more inclined to think that would be the case here. I bought cow's milk from a reputable organic farmer that was awful and then bought some from their brother-in-law that was as rich as ice cream and smelled heavenly. I miss my goat milk...as it made the best kefir I have ever tasted.
