Here is a piece of bacon I had in the fridge (forgotten actually) - it has been wrapped in greaseproof paper for 4 months or so. It is fairly hard - smells like cure parma ham. I use it choped up in bits like panchetta (it has a smoky aroma too as I added a bit of sausagemaking.org smoke powder during the curing process)
Notice that it has started to go white - I think this is partly salts which have dried off during the aging process.
