Hello Wallace
I am not an expert, but have been making sheep milk cheese for 2 years, I used to freeze the milk when I had to store it for more than 2 days, and I know many producers that do that and their cheeses are fine. I have read somewhere that sheep milk can be frozen without troubles because the fat globules are different than cow milk ,the Idea is to freeze as fast as possible for best quality.
When you store milk in the refrigerator(4-7C) for more than 2 days there are bacteria that survive this temperature and decrease the quality(maybe 3 days is OK but not more)
Some cheeses are made taking the cream off, (hard cheeses that are aged for very long time) but most cheeses (blue, washed rind, semi-soft) are best with whole fat milk.
regards
Luis.
