I say if you want Grande, go ahead and buy a case from a distributor. Unopened bags are good for at least a couple months after you buy it; maybe longer. And if you can't use all of it that quickly, you can try to sell some and/or freeze some of it. As I recently learned, freezing isn't such a bad thing. My thawed Grande mozzarella wasn't ideal, but it was still way better than anything else I can get. And it was less than $4 a pound. The only issue I had with the frozen cheese was that it clumped.
For those considering freezing Grande cheese, I can tell you that I've been doing it for 2 years with a great deal of success. The only caution is that once it is thawed, my experience is that it has maximum flavor for only 1-2 days and then it drops off dramatically
. Although very labor intensive, what I do is to get the 30lb. case, and put one 5lb. bag in the fridge, and then break open each bag and put it in 2 lb. freezer zip lock bags and put those bags in a larger freezer bag. The 2lb. increment represents my typical usage for a given night. I take it out of the freezer either the night before or the morning of making pizza in the evening. I have compared the thawed cheese side by side with a new fresh, unfrozen batch of Grande and I can't tell a difference.
But let it sit for 2-3 days in the fridge after thawing and it can get to be almost tasteless. My point is, I've used frozen Grande 4-5 months after purchase and it always tastes like new, if you do it the way I suggest. If you try to freeze a 5 lb. bag as-is, then thaw and started using it over the next couple of weeks, you will be sorely disappointed.
