I bought a cheesemaking kit a month or so ago and have prodcuded one batch so far. I will be trying to make up a new batch of goats cheese this weekend, i write a blog with descriptions and photographs at cheeseathome.blogspot.com My last batch had a slightly sour taste, i follwed the instructions exactly, the temperatures for setting (room temp) were observed and i sterilised everything thoroughly, does anyone have any suggestions what may be going wrong. I used vegetable rennet and a thick full cream Jersey milk.
