Hi Jeddog,
We are neighbours - I am also on the Mornington Peninsula (in Mt. Martha).
I have also had some intermittent problems with blue mould growing very well on some cheeses and not so well on others, even in the same batch. I have found that if they are too wet, it simply doesn't grow so perhaps your lack of 'drying time' did affect your 3. I would suggest that if they are now dry(ish), that you mix a pinch of the roquefort mould spores with a 200ml. boiled COOLED WATER (not hot as this will kill the mould). Allow the mixture to rehydrate for an hour then shake well. Spray the cheeses all over with the mould mixture. Repeat in 5 days if desired.
I worked with a cheesemaker in the USA who only inoculates his blues via spray with the spores rather than putting the mould itself in the milk and he finds this works just as well, in fact, he swears by it.
I hope that helps.
Regards,
TAMARA
