Many manufacturers make/blend several styles & price points for their customers, based upon regional preferences…
Personally, I don’t drink 1 or 2% or skim milk - whole mile is my choice…same with cheese…I prefer whole milk, low moisture - no skim
Grande is a whole milk, as are many Saputo & Sorrento choices, but you can get them in skim milk versions…
I used to use Sorrento, back 10 yrs ago when they were the packer for SYSCO (b4 they were bought out by a French dairy concern) It was a 3% WM mozz - & no “butter fat” bleeding on oven exit - great product…then SYSCO changed…
Straight Grande can be “oily” (butter fat) and that is why many shops blend it with another cheese, especially I believe thos of us w/conveyors…
I blend Saputo WMLM w/a provolone, 50/50 - great stretch, great distinct taste & holds up well for slices & delivery - I felt Grande was to “oily” if my slice biz was off (we can keep pies 4 hrs, if needed)
Everyone has their own preference…find what works 4 you & stick w/it, then build your biz!
