Fat contents from different types of ground beef when drained
I have heard that you can get the fattiest type, drain the grease as normal, and then rinse the meat with water in a colander to make it equivalent to the extra lean fat content. I'm not sure I buy that, and it seems this would rinse off any seasonings used also.


That sounds terrible. Cooked ground beef should be drained if necessary, but not rinsed. It will rinse away a lot of flavor, and I doubt it makes it the equivalent of having bought lean meat in the first place. There is still plenty of fat present in the meat itself.

If you want low fat get extra lean. If you want flavor get 80/20 or 70/30 and drain thoroughly for as little fat as possible. Do yourself a favor though and don't rinse it with water.
