Michael,
I have never heard of it.
I made a move to GRANDE CHEESE about 7 years ago and I have never looked back. If you can get it from you supplier, I would suggest you do a test with it. The melt is the best in the market, and the flavor is far supperior to any other cheese on the market.
The only downside might be price, it is probably the most expensive mozzarella in market usually about $.80 cents over Chicago Mercantile Exchange Cheese Block price. I currently pay $2.51 a pound. However, because of its incredible melt characteristics, you can actually get by with less weight, than with other mozzarella products, and get the same presentation.
