so whycome did American made swiss cheese still have holes in it? I have some holy swiss cheese in the 'fridge right now. Is 'merican milk dirtier than swiss milk?
I would assume that the hay particles either carry in fuel for fermentative microorganisms, carry the fermentative microorganisms, or a combination of both. I wouldn't be surprised if American cheese makers skipped the whole fermentative thing and just injected air.
