Is all organic butter pasture raised and grass fed?
if not, what should I buy from trader joes/sprouts?
I just bought some Kerrygold, It lists grass fed on the packaging. I looked at some other brands but think they are only from animals not treated with Antibiotics and other organic husbandry practices. I don't think not grain feeding is one of them.
You could look at the diffrent packaging and call the makers to see if they could give you info.
I find your lack of bacon disturbing.
If it's any of those things, it'll be on the package in big bold letters. You can bet they won't miss the opportunity to advertize that. I don't know if Trader Joe's carries Kalona, but that's the brand of pastured organic butter I get from the international market and it's all of those good things. Organic Valley is also currently doing a limited edition pastured butter, I saw it at Whole Foods, but it was about ten billion times the price of Kalona.
At Trader Joe's, look for Kerrygold.
