All that requires analysis by a lab at your expense. You may have to provide a couple of samples until you hit the standard, and then convince NYS /FEDS that you will be consistant, to me that spells $$$$$. Personally, (being also a gambler) I would go with convenient labeling, assimilating my cheese to cheddar, unless the inspectors really dislike you, I just do not see this organized take down of you and your product by ag&markets. They really do not have the time nor manpower, and you are not advocating any missrepresentation, you are just saying that your cheese is similar to the standard. Or you can call it "wish it was cheddar" in which case, you are not even saying it resembles cheddar, but would definately arouse customer interest, without even remotly infringing any laws.
