A lot of Trader Joe's cheeses are imported, and I assume that some are grassfed regardless of whether or not the label says so because there are different regulations and husbandry practices in other countries. How do I figure this out? Cheese from Switzerland, France, England, etc.? They had a couple of raw milk (as raw as you get in the United States, at least) cheeses from Switzerland that looked intriguing, but there's not much information there.
No matter what you MUST ASK FOR IT!!
Why? Because the more the cashier hears "I couldn't find grass fed cheese." the more likely the buyers will look at their merchandise plan. Consumers LEAD good merchandisers, and that is why the cashiers are prompted to ask "Did you find everything you needed?" Not only does that question give them a chance to find you something you may have missed, it also allows them to do direct customer service surveys in a timely manner.
I ALWAYS ask for pastured eggs (not cage free) and pastured milk products at TJ's. If enough people ask, the merchant buyer (who buys for THAT region) will find a way to make it happen.
Afterall, they are being compensated for Turn, GM%, and total sales. Make the merchandising team happy through teaching them how to make YOU happy.
It would likely say on the label. I just don't shop at Trader Joes(live in Southern NH). Market Basket in my area stocks Raw VT cheese from pastured cows, and they even have Organic Valley Pastured Raw Chedder as well. The uber expensive co-op down the road has a local farms organic, grass fed cheese/cream/yogurt. All three have something indicating it's pastured, or from grass fed cows. I'd just not buy from Trader Joes if it's that unclear.
Personally- I don't trust Trader Joes for anything. Research the cheese maker and look for that brand. Whole foods and I have plenty of issues with them have fantastic cheeses. And the price is reasonable for the quality and keeps you from eating too much of it. They have a deal with Kerrygold products cheapest anywhere.
