I made my very first cheese yesterday. Everything seemed to go well and I was excited when I took it out of the press this morning. I made Colby and my cheese mold is homemade from PVC. I trimmed a small taste of the cheese and BLEK! It is bitter and tastes like plastic. I am ordering a mold today. Did I waste a whole day or is this what fresh made Colby tasres like? There was no cheese taste at all. Oh, I used fresh cow's milk. I think I'm entering the first stage of depression.
