A few weeks after my posting an email arrived from the cheesemaker explained the situation:
We recently had a batch of Cilia that ripened at an alarming rate due to a maturing room meltdown. That batch was put on hold and was rejected by myself. Unfortunately before I could discard the batch, staff filled some orders from that batch and of all people to be affected by this stuff up, you unfortunately were one! That batch of Cilia was nothing like our normal Cilia which is usually rather mild.The cheesemaker generously offered to send me all sorts of cheese but in fairness I was satisfied with just swapping the cheese for one that was right.
So what I have before you is Cilia as it should be.
