Although I've made a lot of Stilton cheeses I in no way consider myself to be an expert.
Now having said that I will say that Stilton cheeses just flat out stink while they are maturing.
I have tried several different temperature and humidity settings during the aging period and no matter what I try at a certain point a Stilton smells like a neglected gym bag.
Now regardless of this fact, if you do things right, within a few months you will be rewarded with one of the finest examples of blue cheese, available.
Don't let the smell bother you as long as everything else seems to be going well (for instance having the cheese liquify on you).
I have learned that Stilton can also be a deterrent to adverse behaviour from young children.
All I have to do is tell my 8 year old that I'm going to open the Stilton cave, if she doesn't settle down, and it works wonders.
