I have an industrial vacuum sealer like the ones that seal the cheese at Costco.  That has been the best method of preserving PR and it will keep for 6+ months.  The consumer models are better than nothing but not as good.

I don't know why anyone would suggest buying just enough RP for a WEEK.  God it lasts MONTHS!!  And mold growth, while not optimal is not a problem as all.

The worst thing you can do to RP is grate it ahead of time.  THAT will cause the most flavor lose.  Grate as needed.  I keep it in the fridge.....don't know if thats optimal, but it works fine with me.
