List of grass-based dairies:

However, there are far more cheesemakers than what is listed here. The NE has a lot of grass dairies. Here's the VT page of cheesemakers:

Be sure to specifically ask if they are "100% grassfed" if that's what you want. Many say grass-fed/grass-based but still feed grain.
You should try some of the cheese first, before buying a ton of it, to save yourself from some of the truly awful (yet raw, grassfed, etc) cheeses out there. I'd rather buy a fabulous cheese from a farm that feeds a bit of grain.
Seems to me that some farms focus so much on the "health" aspects of their product that they forget about taste. Just my observation!
