Thanks for the input zenith1. Yes, I did run across a lot of info both on the forum and in books...too much and too little. Too many types of cultures used, not enough info on how they will contribute to the final flavor. I did one run of 50/50 LA and TA for Parmesan, asagio, and romano, and I wasn't impressed with the results. The romano, which I had added lipase to, was almost too goaty, but ok. The asagio was mild creamy and totally boring even at 6 months and tasted like the gruyere I had made, also very boring. The parmesan was smooth creamy and mild at 6 months as well. Thankfully, my sweetheart loves them, so I don't have to eat them!
For round two of these cheeses, I'm trying to make changes that will at least make them taste different from each other! I have a pH meter now and that should help give me a better idea of what's going on.
