Where does the chlorine taste in yogurt come from?
Strangely enough, I do live near Campinas (where UNICAMP belongs), where water once was contaminated by human hormones! (Note the source is not in English.) I'm noticing the local water smells very strongly of chlorine; I wonder they're adding water to milk before selling it, or if the cows are drinking the water...
I will try buying milk from different towns to test my theory.
