looking for buffalo milk or unhomogenized cow's milk
Harmony Farms ogranic brand of milk has an unhomogenized whole cow milk (glass bottles and brown cardboard boxes). It is sold at Whole foods, Fiesta farms, Noah's and likely other large supermarkets. You can call them and ask where you can find their products in your neighbordhood
I think I have seen also unhomogenized goat milk, but I never saw buffalo milk for sale in North America.
Most buffalo mlik cheese produced locally is made from cow milk, so I doubt it would be easy to find buffalo milk.
I know this is a long-dormant thread, but since it shows up at the top of searches, I thought I would add some info:
There ARE water-buffalo farmers in Ontario, and you can get real* water buffalo milk. There are a number of farms out by Stirling (and they have a buffalo milk festival in the fall which is DEFINTELY worth going to) and now there is a farm just this side of London called Purple Hill farm where you can also get it with a shorter drive.
*It is real milk from real water buffalo, but it DOES taste subtly different from the milk in Italy. The soil here is different enough to make for a different - and VERY interesting - variant. Make some cheese and you will see what I mean. It is really quite excellent.
