Grass fed beef just has never done it for me. It does have a more intense beef flavor, but it's a more likely style to be tough. Grain fed develops fat more, and you get better marbling. I'm trying to find out, but is it even possible to get prime grade, grass fed beef?

It's just not my thing because, for the most part, I've found grass fed beef to be tougher.

Of course, that being said, grass fed beef is obviously more healthful -- it's got Omega-3 oils, even -- and better for the environment. I guess I'll just have to sit down and make a side-by-side comparison of the two, but I'd be willing to wager that, for hardcore tenderness -- the kind where you don't need a knife to cut it -- you've got to go with grain fed beef. I'm going to keep an open mind, though.
