I use Parmesan cheese infrequently, and whenever I want to use it the
hunk I have in the refrigerator is usually bad. I'm looking for a way
to store Parmesan cheese so that I can have it on hand and it will stay
fresh for more than a few weeks. Here's what I've done so far:

1: In a ZipLock bag. This remained moist but got moldy.

2: Wrapped in parchment paper, and then put in a ZipLock bag. This
remained moist, and took longer to get moldy -- only a slight improvement.
This is how I store all my other cheeses and it works quite well. But
granted, I use up the other cheeses faster than I use the Parmesan.

3: Wrapped in parchment paper; no Ziplock. This didn't get moldy,
but it dried out quite a bit, and was really difficult to grate (and I
have a rather extensive selection of graters, from a cheap $5. one to
several Microplanes).
