We always buy fresh milk. For some reason we decided to try Clover, and regrettable bought six litres of it (long before expiry). The milk wasn't sour, but had a very peculiar and foul taste to it. Everyone in my family agreed it was undrinkable (worse than long life milk), and my daughter (who loves other milk brands) got a sore throat from it. I'm not sure whether this was related to a particular batch, but for now I'm staying away from Clover Milk. We could not drink the milk in any of our hot drinks. It really spoiled everything. User's recommendation: Don't buy it, just not before an adequate response.
