I always buy Golden Flow CY milk and have never had a problem with it going bad too fast.
If you live in New York it is very easy to find CY. Maybe it costs a few dollars more but it is worth it. Fresh and Tasty and Devash is cheaper then Golden Flow, Most of you who complain about the price would buy something that you really really want even if it is a little more expensive so I don’t think that is a good excuse. I really don’t see any excuses in NY for chulav stam. Maybe if you live in the middle of Oklahoma or Kansas somewhere then maybe I can hear an excuse for chulav stam.
