Well amazingly I still have a chunk of this cheese I made 7 months ago left! To be fair it isn't really a very good Gruyere as I used a chunk of store bought Gruyere as my innoculant.
It has been wrapped in a plastic bag and is a bit grotty and, due to it being friendly with a blue cheese I also made ages ago, turned into a nice looking dry blue, almost Stilton like Cheese
.
And it's probably the best tasting cheese I've made, very nice Stilton type flavour, age certainly makes a difference!
