I'm thinking that Stew's has the best dairy products around, save maybe if you know a farmer who can get you raw milk.
I recently bought their cream from the Norwalk store... I love it because it is only pasteurized, not ultra pasteurized, like most grocery store products. It was really good so I tried to calculate the buttercream content out of curiousity. (see the General Topics thread below for more on that). I decided to call Stew's and see what it really was.
The guy said if you buy the pint sized, it has a 36% butterfat content, which is pretty standard for commercial cream. However, if you buy the half gallon sized, it has a buttercream content of 40%. He said they do that because the restaurants they supply prefer the higher cream content.
What all that means is that Stews is one of the few places that sells cream closer to what you can get in Europe. It's really rare to get 40% butterfat content in cream in the States.
Anyhow, for all those in need of heavy cream Stew's seems to be the best place for commercial cream around. And buy the half gallon... (think whipped cream, ice cream, homemade creme fraiche, homemade sour cream or crema, creme brulee, etc. etc. etc.)
